Primary production and humanosphere--is energy sufficient for sustainable humanosphere? (1/148)

There is a growing concern about the sustainability of our humanosphere. Realizing that our consumption of natural resources is soon to exhaust available ones in this globe, we feel the need for more prudent ways to utilize them. In particular, the need would be greater in the ways for the use of the primary products as we are to continue to face the rapid increase in human population. On the contrary, however, we are rapidly losing the traditional customs of their many uses. For instance, rice straws were once a significant raw material for many manufactured products in Japan, while most of them are now simply burned in the paddy. Here I would like to review the current status of primary production on the Earth from the viewpoint of material cycling and to demonstrate that, unless we quickly turn around our ever-increasing demand for more material and more energy, the humanosphere would never enter a stable phase. At the year 2006 A.D., the energy demand of a possibly sustainable humanosphere surpasses the available energy through the global primary production.  (+info)

Solar flair. (2/148)

Design innovations and government-sponsored financial incentives are making solar energy increasingly attractive to homeowners and institutional customers such as school districts. In particular, the passive solar design concept of daylighting is gaining favor among educators due to evidence of improved performance by students working in daylit classrooms. Electricity-generating photovoltaic systems are also becoming more popular, especially in states such as California that have high electric rates and frequent power shortages. To help spread the word about solar power, the U.S. Department of Energy staged its first-ever Solar Decathlon in October 2002. This event featured solar-savvy homes designed by 14 college teams.  (+info)

Use of thermodynamic orientors to assess the efficiency of ecosystems: a case study in the lagoon of Venice. (3/148)

So-called orientors have been introduced at the interface between ecology and thermodynamics. Two have been chosen here to compare the characteristics of five ecological systems: exergy, which is related to the degree of organization of a system and represents the biogeochemical energy of a system, and emergy, which is defined as the total amount of solar energy directly or indirectly required to generate a product or a service. They represent two complementary aspects of a system: the actual state and the past work needed to reach that state. The ratio of exergy to the emergy flow indicates the efficiency of an ecosystem in producing or maintaining its organization. The main system under study is a portion of the Venice Lagoon, which is used as a fish farming basin. Four other aquatic ecosystems were considered for comparison. Results show that the ecosystem within the Venice Lagoon is the one with the highest efficiency in transforming the available inputs in organization of the system. This fact is due to human intervention, which is very limited but also very effective.  (+info)

Biophysical properties of the pelt of a diurnal marsupial, the numbat (Myrmecobius fasciatus), and its role in thermoregulation. (4/148)

Numbats are unusual marsupials in being exclusively diurnal and termitivorous. They have a sparse (1921 hairs cm(-2)) and shallow (1.19 mm) pelt compared with other marsupials. Coat reflectivity is low (19%) for numbats compared with nocturnal marsupials, but absorptivity is similar to that of diurnal North American ground squirrels (72%), indicating that the coat of the numbat may be adapted for acquisition of solar heat. Numbat coat thermal resistance decreases significantly with wind speed from 45.9 s m(-1) (at 0.5 m s(-1)) to 29.8 s m(-1) (at 3 m s(-1)). Erecting the fur significantly increases pelt depth (6.5 mm) and coat resistance (79.2-64.2 s m(-1)) at wind speeds between 0.5 m s(-1) and 3 m s(-1). Numbat coat resistance is much lower than that of other marsupials, and wind speed has a greater influence on coat resistance for numbats than for other mammals, reflecting the low pelt density and thickness. Solar heat gain by numbats through the pelt to the level of the skin (60-63%) is similar to the highest value measured for any mammal. However the numbat's high solar heat gain is not associated with the same degree of reduction in coat resistance as seen for other mammals, suggesting that its pelt has structural and spectral characteristics that enhance both solar heat acquisition and endogenous heat conservation. Maximum solar heat gain is estimated to be 0.5-3.6 times resting metabolic heat production for the numbat at ambient temperatures of 15-32.5 degrees C, so radiative heat gain is probably an important aspect of thermoregulation for wild numbats.  (+info)

Photoelectrochemical solar cell using extract of Eugenia jambolana Lam as a natural sensitizer. (5/148)

The extract of Jambol o (java plum), Eugenia jambolana Lam, was used as a natural sensitizer of a wide band-gap semiconductor (TiO2) in photoelectrochemical solar cells. The natural dye, adsorbed onto the semiconductor surface, absorbs visible light and promotes electron transfer across the dye/semiconductor interface. Photogenerated current and voltage as high as 2.3 mA and 711 mV, respectively, were obtained and effective conversion of visible light into electricity was achieved. The use of a natural product as the semiconductor sensitizer enables a faster and simpler production of cheaper and environmentally friendly solar cells.  (+info)

Applying a nutribusiness approach to increase animal source food consumption in local communities. (6/148)

Animal source foods (ASF) in the diets of schoolchildren are beneficial for supporting optimal physical and cognitive development. Nevertheless, behavioral change and economic development are needed to increase and sustain adequate meat product consumption by schoolchildren in developing countries. A NutriBusiness enterprise may be one way for local communities to promote economic development while increasing the availability of meat for children. This work evaluates the feasibility of a NutriBusiness enterprise involving the production of rabbits and the manufacture of solar dried snack food. Some rabbits would be kept for home use, whereas others would be used in the manufacture of a rabbit-sweet potato dried snack food that could be fed to children or sold for income. The NutriBusiness enterprise would be composed of participants from the community contributing to a cooperative effort for setting up a manufacturing facility and organizing production, manufacturing and marketing functions. A unit operation for rabbit-sweet potato Chiparoos, based on full-capacity operation of a single solar drier would involve up to 110 shareholder families, each producing 240 rabbits/y with 120 used at home and 120 sold for Chiparoos manufacture. Participation in the enterprise would increase the availability to children of iron, zinc and vitamin B-12, and other nutrients, and provide approximately 350 dollars/y additional income for the family.  (+info)

Disinfection of contaminated water by using solar irradiation. (7/148)

Contaminated water causes an estimated 6 to 60 billion cases of gastrointestinal illness annually. The majority of these cases occur in rural areas of developing nations where the water supply remains polluted and adequate sanitation is unavailable. A portable, low-cost, and low-maintenance solar unit to disinfect unpotable water has been designed and tested. The solar disinfection unit was tested with both river water and partially processed water from two wastewater treatment plants. In less than 30 min in midday sunlight, the unit eradicated more than 4 log10 U (99.99%) of bacteria contained in highly contaminated water samples. The solar disinfection unit has been field tested by Centro Panamericano de Ingenieria Sanitaria y Ciencias del Ambiente in Lima, Peru. At moderate light intensity, the solar disinfection unit was capable of reducing the bacterial load in a controlled contaminated water sample by 4 log10 U and disinfected approximately 1 liter of water in 30 min.  (+info)

Is rangeland agriculture sustainable? (8/148)

The objective of this paper is to examine the sustainability of rangeland agriculture (i.e., managed grazing) on a world-wide basis, with a focus on North America. Sustainability is addressed on three fronts: 1) ecological, 2) economic, and 3) social acceptance. Based on previous and on-going research, we suggest that employment of science-based rangeland grazing management strategies and tactics can ensure ecological sustainability. The formidable challenge in employing such technology centers around the need to balance efficiency of solar energy capture and subsequent harvest efficiencies across an array of highly spatially and temporally variable vegetation growing conditions using animals that graze selectively. Failure to meet this fundamental challenge often accelerates rangeland desertification processes, and in some instances, enhances rate and extent of the invasion of noxious weeds. We also suggest that the fundamental reason that ecologically sound grazing management technologies are often not employed in the management of grazed ecological systems is because social values drive management decisions more so than ecological science issues. This is true in both well-developed societies with substantial economic resources and in less-developed societies with few economic resources. However, the social issues driving management are often entirely different, ranging from multiple-use issues in developed countries to human day-to-day survival issues in poorly developed countries. We conclude that the long-term sustainability of rangeland agriculture in 1) developed societies depends on the ability of rangeland agriculturalists to continually respond in a dynamic, positive, proactive manner to ever-changing social values and 2) less-developed societies on their ability to address the ecological and social consequences arising from unsustainable human populations before the adoption of science-based sustainable rangeland management technologies.  (+info)

An object of the present invention is to provide a dye-sensitized solar cell comprising a solid electrolyte and having excellent thermostability, which has the excellent feature of retaining liquid so as to prevent an electrolyte solution from being exuded even under high temperature or pressurized conditions, and a dye-sensitized solar cell module using the same. Such dye-sensitized solar cell comprises: an electrode base material 10; a porous semiconductor layer 20 formed on the electrode base material 10 having a porous surface carrying a sensitized dye; a counter electrode 40, which is disposed so as to face the porous semiconductor layer 20; and an electrolyte layer 30 comprising a redox pair and cationic cellulose or a derivative thereof, which is formed between the electrode base material 10 and the counter electrode 40.
Traditionally, Pt prepared by hydrolysis was used as the counter electrode of dye-sensitized solar cells. But the hydrolysis requires a high-temperature process, so that it is not suitable for flexible substrates like plastics. In addition, noble Pt remarkably increases the cost of dye-sensitized solar cells. Here, we report three types of nanostuctured materials as the counter electrode of dye-sensitized solar cells, including nanostrutured Pt by polyol reduction of Pt precursors, nanocomposites and nanotube films.
The dye-sensitized solar cell, developed in the 1990s, is a non-conventional solar technology that has attracted much attention owing to its stability, low cost, and device efficiency. Power-conversion efficiencies of over 11 % have been achieved for devices that contain liquid electrolytes, whereas solid-state devices that do not require a liquid electrolyte display an overall efficiency of 5 %. Improvement of the efficiency of solid-state dye-sensitized solar cells requires optimization of their various components, such as the hole-transport material, sensitizer, mesoporous TiO2 film, and the blocking layer. This Minireview highlights the current state of the art and future directions of solid-state dye-sensitized solar cell technology. ...
Dye-sensitized solar cells based on iodide/triiodide (I−/I3−) electrolytes are viable low-cost alternatives to conventional silicon solar cells. However, as well as providing record efficiencies of up to 12.0%, the use of I−/I3− in such solar cells also brings about certain limitations that stem from its corrosive nature and complex two-electron redox chemistry. Alternative redox mediators have been investigated, but these generally fall well short of matching the performance of conventional I−/I3− electrolytes. Here, we report energy conversion efficiencies of 7.5% (simulated sunlight, AM1.5, 1,000 W m−2) for dye-sensitized solar cells combining the archetypal ferrocene/ferrocenium (Fc/Fc+) single-electron redox couple with a novel metal-free organic donor-acceptor sensitizer (Carbz-PAHTDTT). These Fc/Fc+-based devices exceed the efficiency achieved for devices prepared using I−/I3− electrolytes under comparable conditions, revealing the great potential of ferrocene-based electrolytes
Panchromatic response is essential to increase the light-harvesting efficiency in solar conversion systems. Herein we show increased light harvesting from using multiple energy relay dyes inside dye-sensitized solar cells. Additional photoresponse from 400-590 nm matching the optical window of the zinc phthalocyanine sensitizer was observed due to Forster resonance energy transfer (FRET) from the two energy relay dyes to the sensitizing dye. The complementary absorption spectra of the energy relay dyes and high excitation transfer efficiencies result in a 35% increase in photovoltaic performance..

In this review, we dissect nanotube growth under a systematic changing of electrode configurations and analyze relevant solar cell constructions as well as performances, in an attempt to explore efficient approaches to harvest solar energy. It is divided into two parts for discussion: planar and nonplanar electrodes, as a conformal coating of anodic nanotubes can be formed on an electrode regardless of its geometric shape. The first part is presented in this paper. To date, the most efficient dye-sensitized solar cells (DSCs) based on anodic nanotubes exhibit a power conversion efficiency of 7~8%, whereas those based on nanoparticles show a higher efficiency of 11~12%. This is due to a lower surface area per photoanode volume for nanotubes with respect to nanoparticles. It is calculated that, for a given photoanode volume, it requires the nanotube diameter to go down to ~30 nm to generate a comparable surface area with nanoparticles of ~20 nm. For single-sided tube growth, three dominant ...

The effects of the grafted nanoparticles on the coordination interactions and structures of electrolytes were investigated using FT-IR spectroscopy and differential scanning calorimetry (DSC). The energy conversion efficiencies were obtained as 3.3 and 2.9% for TiO 2 and SiO 2 based electrolytes, respectively. Good interfacial contact between the electrolyte and the electrodes was also confirmed by field emission scanning electron microscopy (FE-SEM).. AB - Inorganic nanoparticles such as TiO 2 and ...
We report a high molar extinction coefficient heteroleptic polypyridyl ruthenium sensitizer, featuring an electron-rich 3,4-ethylenedioxythiophene unit in its ancillary ligand. A nanocrystalline titania film stained with this sensitizer shows an improved optical absorption, which is highly desirable for practical dye-sensitized solar cells with a thin photoactive layer, facilitating the efficient charge collection. In conjunction with low-volatility and solvent-free electrolytes, we achieved 9.6-10.0% and 8.5-9.1% efficiencies under the air-mass 1.5 global solar illumination. These dye-sensitized solar cells retain over 90% of the initial performance after 1000 h full sunlight soaking at 60 degrees C.

Dye-sensitized solar cells (DSSCs) have been intensely researched for more than two decades. Electrolyte formulations are one of the bottlenecks to their successful commercialization, since these result in trade-offs between the photovoltaic performance and long-term performance stability. The corrosive nature of the redox shuttles in the electrolytes is an additional limitation for industrial-scale production of DSSCs, especially with low cost metallic electrodes. Numerous electrolyte formulations have been developed and tested in various DSSC configurations to address the aforementioned challenges. Here, we comprehensively review the progress on the development and application of electrolytes for DSSCs. We particularly focus on the improvements that have been made in different types of electrolytes, which result in enhanced photovoltaic performance and long-term device stability of DSSCs. Several recently introduced electrolyte materials are reviewed, and the role of electrolytes in different ...
Natural-chlorophyll-related porphyrins, including (2H, Zn, Cu)-protoporphyrin IX (Por-1) and Zn-mesoporphyrin IX (Por-2), and chlorins, including chlorin e6 (Chl-1), chlorin e4 (Chl-2), and rhodin G7 (Chl-3), have been used in dye-sensitized solar cells (DSSCs). For porphyrin sensitizers that have vinyl groups at the β-positions, zinc coordinated Por-1 gives the highest solar-energy-to-electricity conversion efficiency (h) of up to 2.9%. Replacing the vinyl groups of ZnPor-1 with ethyl groups increases the open-circuit voltage (Voc) from 0.61 V to 0.66 V, but decreases the short-circuit current (Jsc) from 7.0 mA·cm−2 to 6.1 mA·cm−2 and the value of h to 2.8%. Density functional theory (DFT) and time-dependent DFT (TD-DFT) calculations suggest that the higher Jsc values of Zn-based porphyrin sensitizers result from the favorable electron injection from the LUMO at higher energy levels. In the case of the chlorin sensitizers, the number of carboxyl protons has a large effect on the photovoltaic
This carrier diffusion length is similar to the light absorption depth at ∼700 nm (Fig. S5†), which suggests that simultaneously high light absorption and charge separation efficiencies can be achieved in the S-annealed Bi2S3 thin films, leading to high overall solar energy conversion efficiencies.53 On the other hand, for un-annealed Bi2S3 films, low signal/noise ratio in the complex conductivity spectra did not permit accurate measurement of mobility.. The solar energy conversion efficiency of the 10 layers of Bi2S3 thin films with and without sulfur vapor annealing at 445 °C was evaluated by photoelectrochemical (PEC) measurements of the wavelength-dependent photon-to-current efficiencies and the potential-dependent light absorption and charge separation efficiencies (Fig. 6). The film thickness and annealing temperature were optimized for maximum photocurrent under white light illumination (Fig. S6†). The IPCE of the S-annealed films reaches a plateau of ∼40% at short wavelengths, ...
Poly(3,4-ethylenedioxxythiophene) (PEDOT), polyaniline (PANI) and polythiophene (PTh) based multi-walled carbon nanotube (MWCNT) composites were successfully prepared using RF-rotating plasma grafting method. Morphological characterizations of composites were determined using scanning electron microscopy (SEM), which showed that conducting polymers (CPs) of PEDOT, PANI and PTh were coated on the surface of CNTs. The surface properties of the Carbon Nanotube (CNT) composites were also determined by using Infrared Spectra (FT-IR), X-ray Photon Spectra (XPS), and Scanning Electron Microscopy-Energy Dispersive X-ray Spectra (SEM-EDX) analysis. X-ray photon spectra results confirmed the formation of the composites. Composites of MWCNT were used in dye-sensitized solar cells (DSSCs) as counter electrodes and exhibited short-circuit photocurrent densities of 11.19, 10.70 and 8.54mA/cm(2) for PANI/MWCNT, PTh/MWCNT and PEDOT/CNT, respectively. ...
New hemicyanine dyes (CM101, CM102, CM103, and CM104) in which tetrahydroquinoline derivatives are used as electron donors and N-(carboxymethyl)-pyridinium is used as an electron acceptor and anchoring group were designed and synthesized for dye-sensitized solar cells (DSSCs). Compared with corresponding dyes that have cyanoacetic acid as the acceptor, N-(carboxymethyl)-pyridinium has a stronger electron-withdrawing ability, which causes the absorption maximum of dyes to be redshifted. The photovoltaic performance of the DSSCs based on dyes CM101CM104 markedly depends on the molecular structures of the dyes in terms of the n-hexyl chains and methoxyl. The device sensitized by dye CM104 achieved the best conversion efficiency of 7.0?% (Jsc=13.4 mA?cm-2, Voc=704 mV, FF=74.8?%) under AM 1.5 irradiation (100 mW?cm-2). In contrast, the device sensitized by reference dye CMR104 with the same donor but the cyanoacetic acid as the acceptor gave an efficiency of 3.4?% (Jsc=6.2 mA?cm-2, Voc=730 mV, ...
The replacement of oxide semiconducting TiO2 nano particles with one dimensional TiO2 nanotubes (TNTs) has been used for improving the electron transport in the dye-sensitized solar cells (DSSCs). Although use of one dimensional structure provides the enhanced photoelectrical performance, it tends to reduce the adsorption of dye on the TiO2 surface due to decrease of surface area. To overcome this problem, we investigate the effects of TiCl4 treatment on DSSCs which were constructed with composite films made of TiO2 nanoparticles and TNTs. To find optimum condition of TNTs concentration in TiO2 composites film, series of DSSCs with different TNTs concentration were made. In this optimum condition (DSSCs with 10 wt% of TNT), the effects of post treatment are compared for different TiCl4 concentrations. The results show that the DSSCs using a TiCl4 (90 mM) post treatment shows a maximum conversion efficiency of 7.83% due to effective electron transport and enhanced adsorption of dye on TiO2 surface.
This thesis focuses on liquid redox electrolytes in dye-sensitized solar cells (DSCs). A liquid redox electrolyte, as one of the key constituents in DSCs, typically consists of a redox mediator, additives and a solvent. This thesis work concerns all these three aspects of liquid electrolytes, aiming through fundamental insights to enhance the photovoltaic performances of liquid DSCs.. Initial attention has been paid to the iodine concentration effects in ionic liquid (IL)-based electrolytes. It has been revealed that the higher iodine concentration required in IL-based electrolytes can be attributed to both triiodide mobility associated with the high viscosity of the IL, and chemical availability of triiodide. The concept of incompletely solvated ionic liquids (ISILs) has been introduced as a new type of electrolyte solvent for DSCs. It has been found that the photovoltaic performance of ISIL-based electrolytes can even rival that of organic solvent-based electrolytes. And most strikingly, ...

Inverse opal (IO) films with mesoporous structures hold promise as high-performance electrodes for various photoelectrochemical devices because of their high specific area as well as their fully connected pore structure. A great challenge to their use is obtaining an intact film of mesoscale colloidal crystals as a template. Here, using the plate-sliding coating method coupled with hot air flow, we successfully deposited mesoscale colloidal crystals onto the substrate. A TiO2 mesoscale IO (meso-IO) with 70 nm pores was then successfully fabricated via atomic layer deposition of TiO2 and subsequent removal of the template. As a photoelectrochemical electrode, the meso-IO structure exhibits enhanced charge transport properties as well as a high specific area. Moreover, dye-sensitized solar cells fabricated using the meso-IO electrode exhibit a higher photocurrent and cell efficiency than a cell constructed using a conventional TiO2 nanoparticle electrode. This meso-IO film provides a new platform for
In a study published March 9 in Nature Chemistry, University of Wisconsin-Madison chemistry Professor Kyoung-Shin Choi presents a new approach to combine solar energy conversion and biomass conversion, two important research areas for renewable energy.. For decades, scientists have been working to harness the energy from sunlight to drive chemical reactions to form fuels such as hydrogen, which provide a way to store solar energy for future use. Toward this end, many researchers have been working to develop functional, efficient and economical methods to split water into hydrogen, a clean fuel, and oxygen using photoelectrochemical solar cells (PECs). Although splitting water using an electrochemical cell requires an electrical energy input, a PEC can harness solar energy to drive the water-splitting reaction. A PEC requires a significantly reduced electrical energy input or no electrical energy at all.. In a typical hydrogen-producing PEC, water reduction at the cathode (producing hydrogen) is ...
Solar cells made with biodegradable components are extremely rare. Ayomi Perera, a Kansas State University doctoral student, created dye-sensitized solar cells out of a protein produced by bacteria and a dye less toxic than traditional dyes. This attractive new research might make solar power even greener.. Dye-sensitized solar cells have been around for decades, and although production is affordable, a few problems burden their potential. Their energy conversion efficiency is only about 11 percent. In the standard p-n junction photovoltaic cells, advances in technology have enabled commercial production of cells with efficiencies upward of 20 percent. In general, dye-sensitized cells continue to improve in efficiency and design, but Perera decided to focus on another problem-the dyes and solvents commonly used in dye-sensitized solar cells can be toxic to people and the environment.. ...
Experimental evidence in the literature has shown that the power efficiency of both solar cells and photocatalytic thin-film electrodes can be enhanced in the presence of metallic nanoparticles because of their surface plasmonic effects. In the field of solar cells, gold nanoparticles have been used to enhance the efficiency of a dye-sensitized solar cell,22 an organic solar cell,23 and a silicon solar cell,24 as shown in Figure 1. Gold or silver nanoparticles have been incorporated into these three types of solar cells in such a way that the photoactive layers of the cells benefit from the enhanced light absorption near the plasmonic structure. For example, gold nanoparticles are embedded in a thin layer of TiO2 under the dye layer in order to enhance the absorption cross-section of the dye-sensitized solar cell (Figure 1A). The top coating of gold nanoparticles with TiO2 is critical to prevent corrosion of gold nanoparticles in the presence of liquid electrolytes. Meanwhile, the thickness ...

Compared to traditional silicon based solar cells, dye-sensitized solar cells, or Graetzel cells, have significantly lower production costs, even though the former still show higher efficiency.
Nanoporous, p-type NiO films were sensitized with coumarin 343 (C343), and the photoinduced electron transfer dynamics was studied in the presence of different concentrations of electrolyte (I-3(-)/I- in propylene carbonate). Electron transfer from the valence band of NiO to the excited C343 is very fast, occurring on time scales from hundreds of femtoseconds to a few picoseconds, but also the subsequent recombination is quite rapid, on the time scale of tens of picoseconds. Nevertheless, formation of an intermediate, attributed to I2-I NiO(+), was observed on the picosecond time scale. Simultaneously the reduced dye was converted back to the C343 ground state, indicating that recombination could be intercepted by 13 reduction. Consistent with that interpretation, we observed oxidized NiO and depletion Of 13 persisting on the millisecond time scale. Complete dye-sensitized solar cells (DSSCs) with these films as photocathode gave up to 10-11% incident photon to current conversion efficiency at ...
A photogated transistor is established based on the dye-sensitized solar cell using nanocrystalline TiO2 films. Voltage-current curves are characterized with three types of transport behaviors: linear increase, saturated plateau, and breakdownlike increase, which are actually of the typical performances for a phototransistor. Moreover, an asymmetric behavior is observed in the voltage-current loops, which is believed to be due to the difference in the effective photoconducting areas rather than the cross-section areas. The photovoltaic voltage between the common counter electrode and drain (VCE-D) is examined as well during the loop measurements, clarifying that the predominant dark process in source and the predominant photovoltaic process in drain are series connected, modifying the electric potential levels, and thus resulting in the characteristic phototransistor behaviors ...

Solar power production and solar energy storage are important research areas for development of technologies that can facilitate a transition to a future society independent of fossil fuel based energy sources. Devices for direct conversion of solar photons suffer from poor efficiencies due to spectrum losses, which are caused by energy mismatch between the optical absorption of the devices and the broadband irradiation provided by the sun. In this context, photon-upconversion technologies are becoming increasingly interesting since they might offer an efficient way of converting low energy solar energy photons into higher energy photons, ideal for solar power production and solar energy storage. This perspective discusses recent progress in triplet-triplet annihilation (TTA) photon-upconversion systems and devices for solar energy applications. Furthermore, challenges with evaluation of the efficiency of TTA-photon-upconversion systems are discussed and a general approach for evaluation and comparison
News release prepared by: Greg Tammen, 785-532-4486, [email protected] Monday, April 9, 2012. Research finds bright future for alternative energy with greener solar cells. MANHATTAN -- Even alternative energy technologies can sometimes be a little greener, according to a Kansas State University graduate students research.. Ayomi Perera, a doctoral student in chemistry, Sri Lanka, is working under Stefan Bossmann, professor of chemistry, to improve dye-sensitized solar cells. The cells are a solar technology that use a dye to help generate energy from sunlight. By creating a less toxic dye and combining it with a bacteria, Pereras solar cells are friendlier to the environment and living organisms -- making an alternative energy solution to fossil fuels even greener.. Dye-sensitized solar cells, which are solar cells with light-absorbing dye, have been around for more than 20 years, but their highest efficiency has stayed close to 11 percent for some time, Perera said. So the thought was ...
The work presented in this thesis is concerned with organic photovoltaic devices (OPVs), in particular with the use of multi-wall carbon nanotubes (MWCNT) to improve device performance. The initial chapters introduce the subject areas of OPVs, carbon nanotubes (CNT) and experimental techniques. Within the thesis, it is demonstrated that MWCNT can be utilised as an interpenetrating, work function tuneable, electrode in bi-layer OPVs. A remarkably low concentration of MWCNT (~1 wt.%) uniformly distributed within the donor layer is shown to greatly increase the cell fill factor (FF) without complicating the process of device fabrication. Furthermore, functionalising the MWCNT with polar surface groups is shown to be an effective means of modifying the open circuit voltage (Voc). This study clearly demonstrates the potential of this approach to significantly increase the power conversion efficiency of bi-layer OPVs. We also introduce, a water soluble acid oxidised multi-wall carbon nanotube ...
Organic photovoltaic devices (OPVs) are fabricated from thin films of organic semiconductors, such as polymers and small-molecule compounds, and are typically on the order of 100 nm thick. Because polymer based OPVs can be made using a coating process such as spin coating or inkjet printing, they are an attractive option for inexpensively covering large areas as well as flexible plastic surfaces. A promising low cost alternative to conventional solar cells made of crystalline silicon, there is a large amount of research being dedicated throughout industry and academia towards developing OPVs and increasing their power conversion efficiency. Single wall carbon nanotubes possess a wide range of direct bandgaps matching the solar spectrum, strong photoabsorption, from infrared to ultraviolet, and high carrier mobility and reduced carrier transport scattering, which make themselves ideal photovoltaic material. Photovoltaic effect can be achieved in ideal single wall carbon nanotube (SWNT) diodes. ...
Federal agency will be looking into concerns regarding fraud in the solar space The United States Treasury Department has begun looking into potential fraud in the solar energy space. The matter involves the federal agency investigating the funding that solar panel manufacturers have received over the course of three years.

The concern lies with the belief that some companies have inflated the market value of their products in order to gain access to more taxpayer money.…. Read More ...
treatment is shown. Semiconducting SWNTs show a significantly higher affinity toward hole doping in comparison to metallic SWNTs; a ≈12-fold and a ≈fivefold drop in sheet resistance, respectively. The results suggest the insignificance of the electronic type of the SWNTs for the film conductivity after hole doping. The SWNT films have been employed as transparent hole extracting electrodes in bulk heterojunction (BHJ) organic photovoltaics. Performances of the devices enlighten the fact that the electrode film morphology dominates over the electronic type of the doped SWNTs with similar sheet resistance and optical transmission. The power conversion efficiency (PCE) of 4.4% for the best performing device is the best carbon nanotube transparent electrode incorporated large area BHJ solar cell reported to date. This PCE is 90% in terms of PCEs achieved using indium tin oxide (ITO) based reference devices with identical film fabrication parameters indicating the potential of the SWNT electrodes ...
At a time when both the environment and social responsibility have an increasingly important role the University of Ljubljana, School of Economics and Business and the Faculty of Electrical Engineering recognised the potential of unused roof surfaces as a source of extra income both in the form of exploitation and sale of electricity. A study from the Laboratory of Photovoltaics and Optoelectronics showed that the solar power plant will also significantly contribute to the reduction of the carbon footprint captive production. The sale of electricity also represents a significant reduction in the high annual costs for the faculty.. Therefore, on the roof of the faculty 432 modules with a total power of 105 kW were installed in December 2011. With the connection of the solar power plant onto the distribution network the Faculty of Economic became the first faculty in Slovenia which, to our knowledge, combined the concern for the environment with the exploitation of the solar energy. Consequently, ...
Silver nanoparticles have been found many interesting applications, such as absorption amplifiers in dye-sensitized solar cells. However, silver nanoparticles are easily oxidized. In order to protect silver nanoparticles, atomic layers of TiO2were deposited onto silver nanoparticles coated to a glass slide. Then the glass slide was exposed to corrosive I-/I3- solutions, and the degree of silver etching was measured via scanning electron microscopy (SEM) and ultraviolet-visible spectroscopy (UVS). It was found that 3 nm (30 cycles) of Al2O3 with 9 nm of (90 cycles) TiO2 could completely protect silver nanoparticles from oxidization ...

A process for fabricating layered semiconductor structures, particularly thin gallium arsenide solar cells, on reusable substrates. The structure is fabricated by depositing a selectively removable layer such as gallium aluminum arsenide onto a substrate, and then depositing a solar cell basic structure on the selectively removable layer. Preferably, the solar cell basic structure includes a layer of p-type gallium arsenide on the layer of gallium aluminum arsenide, a layer of n-type gallium arsenide on the p-type gallium arsenide, and a transparent glass cover over the n-type gallium arsenide layer. The solar cell basic structure is separated from the substrate by selectively dissolving the gallium aluminum arsenide layer, and a new layer of gallium aluminum arsenide is epitaxially deposited upon the exposed face to form a thin, lightweight gallium arsenide solar cell. If the layer of p-type gallium arsenide is about 0.5 microns thick or less, the new layer of gallium aluminum arsenide may be omitted.
Organic small material lead phthalocyanine (PbPc) nanocolumns were prepared via glancing angle deposition (GLAD) on indium tin oxide (ITO) coated glass substrates. Organic electron acceptor materials fullerene (C|sub|60|/sub|) was evaporated onto the nanocolumn PbPc thin films to prepare heterojunction structure ITO/PbPc/C|sub|60|/sub|/Bphen/Al organic photovoltaic cells (OPVs). It is worthwhile to mention that C|sub|60|/sub| molecules firstly fill the voids between PbPc nanocolumns and then form impact C|sub|60|/sub| layer. The interpenetrating electron donor/acceptor structure effectively enhances interface between electron donor and electron acceptor, which is beneficial to exciton dissociation. The short circuit current density (|i|J|/i||sub|sc|/sub|) of organic photovoltaic devices (OPVs) based on PbPc nanocolumn was increased from 1.19 mA/cm|sup|2|/sup| to 1.74 mA/cm|sup|2|/sup|, which should be attributed to the increase of interface between donor and acceptor. The effect of
The process and quality of metallization greatly affects the performance and cost of solar cells. Screen printing of silver paste and fire-through of the silicon nitride antireflection layer is the most widely used method for front side metallization, but it produces a very resistive metal-silicon contact, which significantly limits the cell efficiency. The rapid progress in nanotechnology may provide opportunities to improve solar cell manufacturing process and performance without increasing the fabrication cost. As an example, this paper will discuss the substantial contact resistance reduction that can be achieved using inkjet printed metal nanoparticle inks.
Solar distillation apparatus is disclosed in which the released heat of condensation of the condensing liquid is recovered in a transparent conduit disposed over the liquid to be distilled. Solar energy passes through the transparent conduit and is received on an undulated plate system over which the liquid to be distilled is conducted. A cooling fluid is circulated through the conduit to absorb heat released by the condensing liquid. In one embodiment, the conduit does not concentrate the solar energy. The conduit is preferably disposed at an angle of up to about 25 with the horizontal so that the system is subjected to minimal pressure. In another embodiment the conduit defines a fluid lens system which concentrates the solar energy on the plate system. Provision is also made to recover heat from the condensate and a concentrate of the liquid to be distilled.

A simple and easily processible photovoltaic device has been developed based on borondoped single-walled carbon nanotubes (B-SWNTs) and n-type silicon (n-Si) heterojunctions. The single-walled carbon nanotubes (SWNTs) were substitutionally doped with boron atoms by thermal annealing, in the presence of B 2O 3. The samples used for these studies were characterized by Raman spectroscopy, thermal gravimetric analysis (TGA), transmission electron microscopy (TEM), and x-ray photoelectron spectroscopy (XPS). The fully functional solar cell devices were fabricated by airbrush deposition that generated uniform B-SWNT films on top of the n-Si substrates. The carbon nanotube films acted as exciton-generation sites, charge collection and transportation, while the heterojunctions formed between B-SWNTs and n-Si acted as charge dissociation centers. The current-voltage characteristics in the absence of light and under illumination, as well as optical transmittance spectrum are reported here. It should be ...

TY - JOUR. T1 - Application of Pulse Radiolysis to Mechanistic Investigations of Catalysis Relevant to Artificial Photosynthesis. AU - Grills, David. AU - Polyansky, Dmitry. AU - Fujita, Etsuko. PY - 2017/11/23. Y1 - 2017/11/23. N2 - Taking inspiration from natural photosystems, the goal of artificial photosynthesis is to harness solar energy to convert abundant materials, such as CO2 and H2O, into solar fuels. Catalysts are required to ensure that the necessary redox half-reactions proceed in the most energy-efficient manner. It is therefore critical to gain a detailed mechanistic understanding of these catalytic reactions to develop new and improved catalysts. Many of the key catalytic intermediates are short-lived transient species, requiring time-resolved spectroscopic techniques for their observation. The two main methods for rapidly generating such species on the sub-microsecond timescale are laser flash photolysis and pulse radiolysis. These methods complement one another, and both ...

Concentrating solar plants in the Mojave Desert have brought up issues of water use, because concentrating solar power plants with wet-cooling systems have high water-consumption intensities compared to other types of electric power plants; only fossil-fuel plants with carbon-capture and storage may have higher water intensities.[37] A 2013 study comparing various sources of electricity found that the median water consumption during operations of concentrating solar power plants with wet cooling was 810 gal/MWhr for power tower plants and 890 gal/MWhr for trough plants. This was higher than the operational water consumption (with cooling towers) for nuclear (720 gal/MWhr), coal (530 gal/MWhr), or natural gas (210 gal/MWhr).[38] A 2011 study by the National Renewable Energy Laboratory came to similar conclusions: for power plants with cooling towers, water consumption during operations was 865 gal/MWhr for CSP trough, 786 gal/MWhr for CSP tower, 687 gal/MWhr for coal, 672 gal/MWhr for nuclear, ...

The optical and electrical properties of bulk polymer RR-P3HT (Regio-Regular Poly(3-hexylthiophène-2,5- diyl):PCBM (Methanofullerene Phenyl-C61-Butyric-Acid-Methyl-Ester) heterojunction incorporating single wall carbon nanotubes (SWCNTs) have been already reported by a number of research groups. We investigated a new approach to functionalize CarboLex single wall carbon nanotubes (SWCNTs-e) for increasing their dispersion in various solvents. The addition of SWCNTs-e in the matrix of P3HT:PCBM improves the photovoltaic (PV) characteristics. Results show that the photovoltaic parameters depend on the concentration of SWCNTs-e. The incorporation of low concentrations of SWCNTs-e in the photoactive layer increases the current density Jsc before annealing. We attribute the improved performance to partial crystallisation of the RR-P3HT. As revealed by XRD studies and confirmed by the absorbance spectra which exhibit the characteristic 600 nm shoulder. Interestingly, we observed also that doping the ...

In each reflection within the fiber, the light has the opportunity to interact with the nanostructures that are coated with the dye molecules, Wang explained. You have multiple light reflections within the fiber, and multiple reflections within the nanostructures. These interactions increase the likelihood that the light will interact with the dye molecules, and that increases the efficiency.. Wang and his research team have reached an efficiency of 3.3 percent and hope to reach 7 to 8 percent after surface modification. While lower than silicon solar cells, this efficiency would be useful for practical energy harvesting. If they can do that, the potentially lower cost of their approach could make it attractive for many applications.. By providing a larger area for gathering light, the technique would maximize the amount of energy produced from strong sunlight, as well as generate respectable power levels even in weak light. The amount of light entering the optical fiber could be increased by ...
Although the bulk of photovoltaic devices today are used for purely practical and economic reasons, a potential benefit of photovoltaics is that PV is one of the most environmentally benign of any electricity generating source. The environmental impact of electricity generation, particularly the greenhouse effect, adds an important reason for examining photovoltaics. A brief overview of the greenhouse effect is given below.. The Earths temperature is a result of an equilibrium established between the incoming radiation from the sun and the energy radiated into space by the Earth. The outgoing radiation emitted by the Earth is strongly affected by the presence and composition of the Earths atmosphere. If we had no atmosphere, as on the moon, the average temperature on the Earths surface would be about -18°C. However, a natural background level of 270 ppm carbon dioxide (CO2) in the atmosphere absorbs outgoing radiation, thereby keeping this energy in the atmosphere and warming the Earth. The ...

0029] Typically, the n-type semiconductor layer 22 of the solar cell 2 may be made of an inorganic material and the p-type semiconductor layer 23 may be made of an organic material, or the n-type semiconductor layer 22 may be made of an organic material and the p-type semiconductor layer 23 may be made of an inorganic material. For example, in the manufacture, because zinc oxide (ZnO) and TFB material (poly(9,9-dioctylfluorene-co-N (4-butylphenyl)diphenylamine) both have the feature of insignificantly absorption of solar light with a wavelength above 400 nm, each of them can be used for forming the n-type semiconductor layer 22 and p-type semiconductor layer 23, respectively, As such, the n-type semiconductor layer 22 and p-type semiconductor layer 23 do not significantly absorb solar energy, and, when the thicknesses of the ZnO layer and the TFB layer are larger than 400 nm, the feature of insignificant absorption of solar light with the wavelength above 400 nm becomes even more obvious ...
This initial research report, appearing before the formal commencement of the STEEP-RES project, focuses on the background and context of the project which is intended to make a socio-technical-ecological assessment of prerequisites to and effects of introducing renewable energy sources (RES) into rural communities of the coastal Tanzania and Mozambique. Therefore a short review of the scientific literature is made dealing with societal prerequisites and repercussions of electrification. Technical aspects related to the availability of natural resources and technologies for renewable energy resources utilisation are also briefly covered along with some very brief remarks on possible environmental repercussions. The review of the social context covers > 45 papers dealing with different experiences of electrification in developing countries relating to renewable energy applicable for poverty alleviation in rural settings. The primary energy sources in rural East Africa are biofuels and electricity plays a

N2 - The 3-dimensional imaging of complete polymer solar cells prepared by roll-to-roll coating was carried out using high-resolution 1322 nm optical coherence tomography (OCT) system. We found it possible to image the 3-dimensional structure of the entire solar cell that comprises UV-barrier, barrier material, adhesive, substrate and active solar cell multilayer structure. The achievable resolution was 12 μm in the lateral plane and 4.5 μm in the depth. We found that the OCT technique could be readily employed to identify coating defects in the functional layers. We finally identify the limitations of the ...
Lastly, water-splitting solar panels skips the step of first generating electricity for electrolysis, where metals directly absorb the solar energy and release electrons needed to split the water molecule, by using solar power to corrode oxides in order to obtain hydrogen or to convert solar power to electricity to perform electrolysis.. Once obtained, the hydrogen has to be transported. Under the Maxi Taxi concept, it would be best to produce hydrogen locally, that way the cost of transporting it is cheaper. For transporting the fuel, there are three major ways of making it transportable: compression; liquefaction; and binding it to another atom or molecule. Compression is attractive, since not much of the energy is lost. Liquefying takes a lot of energy that cannot be easily recovered. Also, compressed hydrogen is slightly more expensive than liquefied hydrogen to transport and distribute, since liquid hydrogen takes up less space than a gas. But compressed hydrogen is much cheaper to buy at ...
Fargo, N.D. - Researchers at North Dakota State University and the University of South Dakota are using computer simulations to determine whether quantum dots or nanowires would make better solar collectors for the development of future solar panels. The research team includes Andre Kryjevski, research assistant professor of physics and NDSU Center for Computationally Assisted Science and Technology; Svetlana Kilina, NDSU assistant professor of chemistry and biochemistry, and Dimitri Kilin, University of South Dakota. The teams research results are published in the American Institute of Physics Journal of Renewable and Sustainable Energy at http://dx.doi.org/10.1063/1.4817728 The group used computational modeling to examine quantum dots, one-dimensional chains of quantum dots and a nanowire to determine their potential application for solar energy collection. The results, Kryjevski said, show that placing amorphous quantum dots in an array or merging them into a nanowire results in what may be ...
Biomass is a renewable source of energy. Biomass can be converted into bio-fuel. Bio-fuels to operate machinery, electric generators, transports, and other pertinent equipment.. Bio-fuel: Combustible fuels generated from contemporary biological process that convert biomass into fuels that are in solid, liquid or gas forms. So much biomass around the world is wasted. There are still so many countries that rely on firewood for cooking. Even in the U.S.A., they chop down trees and turn them into charcoal. All over the world trees are wastefully cut down for fuel.. This design will help prevent the waste of trees. Tree trimmings can be turned into charcoal. Any type of biomass (even grass) can be turned into charcoal while collecting methane in the process. Charcoal making machines powered by methane can be operated to turn the charcoal dust into any charcoal form salable in the market.. The design may be further modified to generate electricity in the process. Coils filled with water can be wrapped ...

The Romans conquered most of the island (up to Hadrian's Wall in northern England) and this became the Ancient Roman province of Britannia. In the course of the 500 years after the Roman Empire fell, the Britons of the south and east of the island were assimilated or displaced by invading Germanic tribes (Angles, Saxons, and Jutes, often referred to collectively as Anglo-Saxons). At about the same time, Gaelic tribes from Ireland invaded the north-west, absorbing both the Picts and Britons of northern Britain, eventually forming the Kingdom of Scotland in the 9th century. The south-east of Scotland was colonised by the Angles and formed, until 1018, a part of the Kingdom of Northumbria. Ultimately, the population of south-east Britain came to be referred to as the English people, so-named after the Angles. Germanic speakers referred to Britons as Welsh. This term came to be applied exclusively to the inhabitants of what is now Wales, but it also survives in names such as Wallace and in the ...
