Book excerpt: Quartz, as the silicon source material, has been identified to be plentifully available at a sufficient purity and reactivity to meet the objective of this program. Further investigations of deposits are warranted when the program reaches a higher level of development. Carbon, as a reductant for quartz, must be made available so as to have suitable reactivity in conjunction with high purity, especially with respect to boron and phosphorus. A detailed experimental plan has been developed to do this. Different sources of carbon have been selected to be subjected to various purification methods and reactivity-enhancement processes. A developmental-scale arc furnace has been installed and will undergo start-up during January. This equipment will be ready next quarter to perform quartz-carbon reactivity testing. An updated economic analysis of the Dow Corning Process for SoG-Si shows the manufacturing cost to be $7.37/kg (January 1975 dollars) at a level of 2700 metric tons per year. The capital investment would be $38.2 million.

Download or read book Solar Silicon Processes written by Bruno Ceccaroli and published by CRC Press. This book was released on 2016-10-03 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polycrystalline silicon (commonly called "polysilicon") is the material of choice for photovoltaic (PV) applications. Polysilicon is the purest synthetic material on the market, though its processing through gas purification and decomposition (commonly called "Siemens" process) carries high environmental risk. While many current optoelectronic applications require high purity, PV applications do not and therefore alternate processes and materials are being explored for PV grade silicon. Solar Silicon Processes: Technologies, Challenges, and Opportunities reviews current and potential future processing technologies for PV applications of solar silicon. It describes alternative processes and issues of material purity, cost, and environmental impact. It covers limits of silicon use with respect to high-efficiency solar cells and challenges arising from R&D activities. The book also defines purity requirements and purification processes of metallurgical grade silicon (MG-Si) and examines production of solar grade silicon by novel processes directly from MG-Si and/or by decomposition of silane gas in a fluidized bed reactor (FBR). Furthermore, the book: Analyzes past research and industrial development of low-cost silicon processes in view of understanding future trends in this field. Discusses challenges and probability of success of various solar silicon processes. Covers processes that are more environmentally sensitive. Describes limits of silicon use with respect to high-efficiency solar cells and challenges arising from R&D activities. Defines purity requirements and purification processes of MG-Si. Examines production of solar grade silicon directly from MG-Si.

Available in PDF, EPUB and Kindle. Book excerpt: Installation of the Direct Arc Reactor (DAR) system was completed. Reactor start-up was initiated after modifications were made as recommended by the safety start-up team. A series of experiments was started aimed at establishing baseline operating conditions for the DAR. These experiments use pure quartz and unpurified charcoal as reactants. Two baseline experiments were completed. The longest experiment (48h) was terminated on schedule after producing 110 kg of silicon. After initial reactor conditioning, silicon was produced at 2.6 kg/h using 28 kWh/kg. A program was developed with the goal of identifying various carbon reductants having boron and phosphorus concentrations of about 1 ppm or less. The necessity is stressed of carrying out a development program for silicon purification by unidirectional solidification. This must be done in parallel with the development program for DAR-silicon production in order to develop the overall Dow Corning Process for solar-grade silicon within the time goals of the LSSA Project. The technology for unidirectional solidification requirements under the Dow Corning Process neither exist nor are they being developed.

This book was released on 2012-06-07 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today, the silicon feedstock for photovoltaic cells comes from processes which were originally developed for the microelectronic industry. It covers almost 90% of the photovoltaic market, with mass production volume at least one order of magnitude larger than those devoted to microelectronics. However, it is hard to imagine that this kind of feedstock (extremely pure but heavily penalized by its high energy cost) could remain the only source of silicon for a photovoltaic market which is in continuous expansion, and which has a cumulative growth rate in excess of 30% in the last few years. Even though reports suggest that the silicon share will slowly decrease in the next twenty years, finding a way to manufacture a specific solar grade feedstock in large quantities, at a low cost while maintaining the quality needed, still remains a crucial issue. Thin film and quantum confinement-based silicon cells might be a complementary solution. Advanced Silicon Materials for Photovoltaic Applications has been designed to describe the full potentialities of silicon as a multipurpose material and covers: Physical, chemical and structural properties of silicon Production routes including the promise of low cost feedstock for PV applications Defect engineering and the role of impurities and defects Characterization techniques, and advanced analytical techniques for metallic and non-metallic impurities Thin film silicon and thin film solar cells Innovative quantum effects, and 3rd generation solar cells With contributions from internationally recognized authorities, this book gives a comprehensive analysis of the state-of-the-art of process technologies and material properties, essential for anyone interested in the application and development of photovoltaics.
