It also discusses the latest semiconductor heterojunction models and presents modern analysis concepts. Thin film technology is explained with an emphasis on current and future techniques for mass production, and the book closes with a compendium of failure analysis in photovoltaic thin film modules. With its overview of the semiconductor physics and technology needed, this practical book is ideal for students, researchers, and manufacturers, as well as for the growing number of engineers and researchers working in companies and institutes on chalcogenide photovoltaics.

Book Progress in the Development of High Efficiency Thin Film Cadmium Sulfide Solar Cells

Download or read book Progress in the Development of High Efficiency Thin Film Cadmium Sulfide Solar Cells written by A.M. Barnett and published by . This book was released on 1978 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thin film photovoltaic cells of cadmium sulfide/copper sulfide have been developed and optimized for specific cell designs. The optimization has been achieved by changing material parameters and the technology of the electrical contacts as dictated by detailed analyses of loss mechanisms in the cells. Additional design changes are needed to further increase the energy conversion efficiency in direct sunlight beyond the present value of8.5%. The application of analytic techniques to specific cell designs is responsible for the improvements achieved to date, and it is expected to lead to a basic cadmium sulfide/copper sulfide cell with an efficiency over10%.It is anticipated that the application of similar analytic techniques to a modified cell of cadmium -zinc sulfide/copper sulfide, coupled with constant interplay between theoretical and experimental results will lead to an energy conversion efficiency in direct sunlight of up to 14%.The material properties and electro-optical characteristics of the present high efficiency CdS/Cu2S cells and initial results using the mixed cadmium zinc sulfide will be presented. This paper describes the analysis driven technology innovations which have led to the development of reproducible thin film cadmium sulfide solar cells with energy conversion efficiencies in direct sunlight of greater than 8.5%. A photovoltaic effect in CdS was first reported by Reynolds for a junction made by depositing a thin film of copper on a cadmium sulfide film (1). Later work established that the actual junction was between CdS and Cu2S (2). A substantial number of research efforts have since been conducted on this photovoltaic heterojunction and although some variation exists, cells have generally been made by reacting a vapor deposited cadmium sulfide film with a cuprous ion solution. A major research effort aimed towards space applications was conducted during the 1960's (3,4).These and many other investigators have reported conversion efficiencies in sunlight of between 5 and 6% with a limited number reporting efficiencies up to 70. Thin film cells with energy conversion efficiencies of7.8% when measured in direct sunlight were recently reported (5,6). The methodology and experiments which lead to the further development of 8.5%CdS/Cu2S cells follows.

Book Masters Theses in the Pure and Applied Sciences

Download or read book Masters Theses in the Pure and Applied Sciences written by Wade H. Shafer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 350 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 1 957, 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 thought 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 36 (thesis year 1991) a total of 11,024 thesis titles from 23 Canadian and 161 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 36 reports theses submitted in 1991, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Book Solution Processing for Copper Indium Sulfide Solar Cells

Download or read book Solution Processing for Copper Indium Sulfide Solar Cells written by Stephen Thacker Connor and published by Stanford University. This book was released on 2011 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, the field of photovoltaics has become increasingly important due to rising energy demand and climate change. While most solar cells are currently composed of crystalline silicon, devices with thinner films of inorganic absorber materials might allow production at a greater scale due to their lower materials cost. In particular, thin films of CuInS2 are promising solar absorber materials due to their high efficiencies and low required thicknesses. However, the fabrication of thin film solar cells currently requires expensive vacuum techniques. As an alternative, solution-based deposition techniques have been proposed as a route to low-cost and high-throughput electronic device fabrication. I have studied how film growth depends on solutuion deposited precursor film quality, with the goal of producing large grained films of CuInS2 through solution processing. In the first approach, we used solvothermal decomposition of organometallic precursors at moderate temperatures to produce nanoparticles of CuInS2. Thin films of these nanoparticles were cast onto molybdenum coated glass and further processed to create CuInS2 solar cells. We found that performance was dependent on film porosity, grain size, and stoichiometry of the nanoparticles. Films with grain sizes of ~200nm were attained, from which 1.3% efficient solar cells were made. In addition, we showed that this synthesis could be extended to produce CuInS2 nanoparticles with partial substitution of Fe, Zn, and Ga. In the second approach, we synthesized an air-stable hybrid organometallic/nanoparticle ink at room temperature in ambient conditions through a vulcanization reaction. This ink could be coated onto substrates in smooth layers, and further reactive annealing formed large grained CuInS2 films. This process was characterized, and a correlation between residual carbon and grain growth was found. Additionally, the chemical transformation between precursor layers and final sulfide thin film was analyzed, with an emphasis on the difference between sulfurization and selenization. We demonstrated that the sulfurization process was producing morphological defects due to its nucleation limited growth mechanism. However, it was modified to more closely resemble the diffusion limited selenization mechanism, thus producing flat films of CuInS2 with grain sizes of ~500nm.
