Available in PDF, EPUB and Kindle. Book excerpt: Solar cells are semiconductor devices that convert light photons into electricity in photovoltaic energy conversion and can help to overcome the global energy crisis. Solar cells have many applications including remote area power systems, earth-orbiting satellites, wristwatches, water pumping, photodetectors and remote radiotelephones. Solar cell technology is economically feasible for commercial-scale power generation. While commercial solar cells exhibit good performance and stability, still researchers are looking at many ways to improve the performance and cost of solar cells via modulating the fundamental properties of semiconductors. Solar cell technology is the key to a clean energy future. Solar cells directly harvest energy from the sun’s light radiation into electricity are in an ever-growing demand for future global energy production. Solar cell-based energy harvesting has attracted worldwide attention for their notable features, such as cheap renewable technology, scalable, lightweight, flexibility, versatility, no greenhouse gas emission, environment, and economy friendly and operational costs are quite low compared to other forms of power generation. Thus, solar cell technology is at the forefront of renewable energy technologies which are used in telecommunications, power plants, small devices to satellites. Aiming at large-scale implementation can be manipulated by various types used in solar cell design and exploration of new materials towards improving performance and reducing cost. Therefore, in-depth knowledge about solar cell design is fundamental for those who wish to apply this knowledge and understanding in industries and academics. This book provides a comprehensive overview on solar cells and explores the history to evolution and present scenarios of solar cell design, classification, properties, various semiconductor materials, thin films, wafer-scale, transparent solar cells, and so on. It also includes solar cells’ characterization analytical tools, theoretical modeling, practices to enhance conversion efficiencies, applications and patents.
Book Synopsis Design and Synthesis of Novel Perylenemonoimide Dyes for Solar Energy Conversion by : Allison Elizabeth Curtze
Download or read book Design and Synthesis of Novel Perylenemonoimide Dyes for Solar Energy Conversion written by Allison Elizabeth Curtze and published by . This book was released on 2020 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: While the protection offered by BH dyes affords photocathodes with long-term stability and high photocurrents in low pH aqueous conditions, p-DSPEC devices sensitized with BH4 have achieved less than ideal faradaic efficiencies attributed to catalyst decomposition. Thus, another new dye, cat-i, was designed and synthesized, featuring a pyridine moiety, which gives rise to the formation of a stable dye-catalyst supramolecule via axial coordination of the dye to the Co center of a well-known water reduction catalyst, Co(dmgBF2)2. Further, this dye-catalyst complexation could facilitate electron transfer from the photoexcited dye to the cobaloxime catalyst. When used as a sensitizer in a p-DSPEC device, the cat-i-cobaloxime complex exhibits significantly higher photocurrents than cat-i alone and produces H2 with 87% Faradaic efficiency.

Available in PDF, EPUB and Kindle. Book excerpt: The operation of everything in the universe needs a special „material“-energy. The earth is no exception. There are many kinds of energy sources on earth. But where does the earth‘s energy come from? The answer is that everything grows under the sun. Developing renewable energy is of strategic importance to achieve sustainable energy supply. Simulating natural photosynthesis is the ultimate goal of effi cient solar energy conversion. Photovoltaic technology has been widely used in industry and will be one of the major energy sources in the future. Developing new materials and structures, the photoelectric conversion effi ciency of solar cells will be improved day by day, and solar cells will attract more and more attention. This book presents principles of solar photovoltaic conversion, and introduces the physical and chemical processes involved. Mechanisms which affect solar cell performance are also discussed.
Book Synopsis Synthesis of Novel Chalcogenopyrylium Dyes for Dye-sensitised Solar Cells by : Chi Wing Szeto
Download or read book Synthesis of Novel Chalcogenopyrylium Dyes for Dye-sensitised Solar Cells written by Chi Wing Szeto and published by . This book was released on 2015 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: Novel chalcogenopyrylium dyes for dye-sensitized solar cells were synthesized, including monomethine dyes with different chalcogenopyrylium cores, dyes with phosphonate or symmetrical carboxylic acid anchoring groups, and dyes with electron-donating triphenylamine and N, N-dimethylphenylamine moieties. The synthetic strategy for chalcogenopyrylium dyes is to generate the key chalcogenopyranone intermediate initially, followed by condensation with 4-methylpyrylium dyes. The reactive anchoring carboxylic acid group was protected in the synthesis by an ethyl ester and the deprotection method of these dyes is developed in this thesis.

Book Synopsis Materials for Sustainable Energy by : Vincent Dusastre
Download or read book Materials for Sustainable Energy written by Vincent Dusastre and published by World Scientific. This book was released on 2011 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: The search for cleaner, cheaper, smaller and more efficient energy technologies has to a large extent been motivated by the development of new materials. The aim of this collection of articles is therefore to focus on what materials-based solutions can offer and show how the rationale design and improvement of their physical and chemical properties can lead to energy-production alternatives that have the potential to compete with existing technologies. In terms of alternative means to generate electricity that utilize renewable energy sources, the most dramatic breakthroughs for both mobile (i.e., transportation) and stationary applications are taking place in the fields of solar and fuel cells. And from an energy-storage perspective, exciting developments can be seen emerging from the fields of rechargeable batteries and hydrogen storage.
Book Synopsis Synthesis, Photophysical Properties, and Biological Evaluation of Novel Chalcogenorhodamine Dyes for Applications in P-gp Inhibition, Reversible Fluorescence Probes, and Photodynamic Therapy of Cancer by : Gregory Allen Schamerhorn
Download or read book Synthesis, Photophysical Properties, and Biological Evaluation of Novel Chalcogenorhodamine Dyes for Applications in P-gp Inhibition, Reversible Fluorescence Probes, and Photodynamic Therapy of Cancer written by Gregory Allen Schamerhorn and published by . This book was released on 2014 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based upon the promising results of previous libraries that incorporated a thioamide/amide "switch", we have prepared a new library of thiorhodamine analogues in order to more closely examine the effects of isolated structural modifications on P-gp activity. Biological examination of these thiorhodamines suggested that P-gp expressing cells exhibit "selection rules" with respect to incorporation of amide and/or thioamide functionality; rates of transport by the pump for amide-bearing derivatives were more rapid than for thioamides. The results of this library suggested that appropriate functionalization of rhodamine dyes could allow one to tune their in vivo properties to be desirable for a particular application. To this end, we have prepared several libraries of selenorhodamine dyes and examined them for their ability to function as photosensitizers in the photodynamic therapy of malignant cells, as well as in the selective depletion of alloreactive T cells in extracorporeal photopheresis. Thioamide-bearing dyes were found to be effective photosensitizers in photodynamic therapy (PDT), whereas amide-bearing dyes showed desirable activity in extracorporeal photopheresis. Recently, the use of tellurorosamine dyes as reversible fluorescent probes for the continuous monitoring of reactive oxygen species in vivo was reported. Such probes are based on the Te(II)/Te(IV) redox cycle. We have evaluated several tellurorosamine dyes for their potential use as reversible probes, explored various methods of their oxidation, and examined their chemical stabilities under cell-like conditions. Oxidized analogues of tellurorosamine dyes in which the 9-phenyl substituent has been functionalized with ortho-methyl groups display increased hydrolytic stability relative to those bearing solely hydrogens at ortho-positions. Our original examination of thiorhodamine dyes and their effects on P-gp activity also showed that dyes having fused ring moieties at the 3-amino position resulted in decreased ATPase stimulation and increased binding affinity relative to those having dimethylamino fragments at the 3-amino position. Hence, we have developed synthetic routes towards rhodamine dyes having fused rings at both the 3- and 6-amino positions in an effort to develop novel, potent inhibitors of P-gp. Initial results suggest that selenorhodamines having fused ring moieties at both the 3- and 6-amino positions are more effective photosensitizers in PDT of cancer cells than those having fused rings only at the 3-amino position. Furthermore, oxidized analogues of tellurorosamine dyes functionalized with fused rings at both the 3- and 6-amino positions display increased hydrolytic stability relative to the analogous 3,6-bis(dimethylamino) tellurorosamine derivatives.
