Book Synopsis Properties of Thin Film Cadmium Sulfide Used in Cadmium Telluride/cadmium Sulfide Solar Cell by : Xiawa Wu
Download or read book Properties of Thin Film Cadmium Sulfide Used in Cadmium Telluride/cadmium Sulfide Solar Cell written by Xiawa Wu and published by ProQuest. This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: CdTe/CdS solar cell is one of the promising low cost high efficiency thin film solar cells. In this work, thin film CdS properties and the effect of CdS surface conditions on CdTe growth and performance of polycrystalline CdTe/CdS thin film solar cells are investigated. Thin film CdS optical, structural and chemical properties both as deposited and after CdCl 2 heat treatment are measured. CdS surface chemical state is studied by analyzing its surface chemistry after different surface treatments. Qualitative and quantitative measurements indicate sulfate and sulfite phases on thin film CdS surfaces as well as single crystal CdS, caused by oxidation in the air. The degree of CdS oxidation is highly dependent on thermal treatment ambient, temperature and time. Results indicate reduction in grain size and smoother morphology for CdTe deposited on heavily oxidized CdS compared to chemically reduced CdS surface. Solar cell open circuit voltage is much lower on cells with heavily oxidized CdS surface.
Book Synopsis Mercury Cadmium Telluride by : Peter Capper
Download or read book Mercury Cadmium Telluride written by Peter Capper and published by John Wiley & Sons. This book was released on 2011-06-20 with total page 610 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mercury cadmium telluride (MCT) is the third most well-regarded semiconductor after silicon and gallium arsenide and is the material of choice for use in infrared sensing and imaging. The reason for this is that MCT can be ‘tuned’ to the desired IR wavelength by varying the cadmium concentration. Mercury Cadmium Telluride: Growth, Properties and Applications provides both an introduction for newcomers, and a comprehensive review of this fascinating material. Part One discusses the history and current status of both bulk and epitaxial growth techniques, Part Two is concerned with the wide range of properties of MCT, and Part Three covers the various device types that have been developed using MCT. Each chapter opens with some historical background and theory before presenting current research. Coverage includes: Bulk growth and properties of MCT and CdZnTe for MCT epitaxial growth Liquid phase epitaxy (LPE) growth Metal-organic vapour phase epitaxy (MOVPE) Molecular beam epitaxy (MBE) Alternative substrates Mechanical, thermal and optical properties of MCT Defects, diffusion, doping and annealing Dry device processing Photoconductive and photovoltaic detectors Avalanche photodiode detectors Room-temperature IR detectors
Book Synopsis Varying Cadmium Telluride Growth Temperature During Deposition to Increase Solar Cell Reliability by :
Download or read book Varying Cadmium Telluride Growth Temperature During Deposition to Increase Solar Cell Reliability written by and published by . This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method for forming thin films or layers of cadmium telluride (CdTe) for use in photovoltaic modules or solar cells. The method includes varying the substrate temperature during the growth of the CdTe layer by preheating a substrate (e.g., a substrate with a cadmium sulfide (CdS) heterojunction or layer) suspended over a CdTe source to remove moisture to a relatively low preheat temperature. Then, the method includes directly heating only the CdTe source, which in turn indirectly heats the substrate upon which the CdTe is deposited. The method improves the resulting CdTe solar cell reliability. The resulting microstructure exhibits a distinct grain size distribution such that the initial region is composed of smaller grains than the bulk region portion of the deposited CdTe. Resulting devices exhibit a behavior suggesting a more n-like CdTe material near the CdS heterojunction than devices grown with substrate temperatures held constant during CdTe deposition.
Book Synopsis Recent Advances in Thin Film Photovoltaics by : Udai P. Singh
Download or read book Recent Advances in Thin Film Photovoltaics written by Udai P. Singh and published by Springer Nature. This book was released on 2022-09-02 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides recent development in thin-film solar cells (TFSC). TFSC have proven the promising approach for terrestrial and space photovoltaics. TFSC have the potential to change the device design and produce high efficiency devices on rigid/flexible substrates with significantly low manufacturing cost. TFSC have several advantages in manufacturing compared to traditional crystalline Si-solar cells like less requirement of materials, can be prepared with earth’s abundant materials, less processing steps, easy to dispose, etc. Several universities/research institutes/industry in India and abroad are involved in the research area of thin-film solar cells. The book helps the readers to find the details about different thin-film technologies and its advancement at one place. Each chapter covers properties of materials, its suitability for PV applications, simple manufacturing processes and recent and past literature survey. The issues related to the development of high efficiency TFSC devices over large area and its commercial and future prospects are discussed.

This book was released on 2012-12-06 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thougtit that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 31 (thesis year 1986) a total of 11 ,480 theses titles trom 24 Canadian and 182 United States universities. We are sure that this broader base tor these titles reported will greatly enhance the value ot this important annual reterence work. While Volume 31 reports theses submitted in 1986, on occasion, certain univer sities do re port theses submitted in previousyears but not reported at the time.
