Book Description
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.

Book Description
Solar Panel Processing discusses solar cell technology including theory of operation, efficiency, materials, research on silicon processing, thin-film processing, polymer processing, nanoparticle processing, and transparent conductors. The hand book presents detailed descriptions of thin film processing of amorphous silicon, CdTe, CIGS, and GaAs panels. The handbook details Key Growth Drivers us solar panel usage, Challenges Facing The Solar Power Industry , Cost Of A Photovoltaic System, and Operating Metrics 0f A Photovoltaic Systems Increasing focus on the demand for energy led to conduct this study, which determines the current status of thin films used in various kinds of energy. Our goal was to assess the value of thin films used in the fabrication of six energy technologies for 2007, project 2008 demand, and then forecast thin film demand growth to 2013. This study focuses on the merits of thin films and main key objective was to present a comprehensive analysis of the current market for thin films and its future direction. Global demand for traditional fossil fuels has risen at an unprecedented rate over the lest several years. The economics of supply and demand have driven prices of oil, gas, and coal to record levels. In addition, fossil fuels are considered a source of pollution that aids climate change. Nations have responded by instituting reductions in activities that require the use of fossil fuels and by searching for alternative energy methods. This handbook examines traditional crystalline and thin film photovoltaic fabrication and operation. Thin films are often applied to reduce the cost of product fabrication, improve performance, and provide more flexibility in product design. In addition, they are environmentally benign. The Solar Panel Processing Handbook study of thin films in energy presents current and emerging technologies for various types of solar cells, detaisl the industry structure of each segment, discusses the competitive environment of each type of energy, and reviews current and future applications for thin films. Handbook study will be of interest to those who make solar cells, semiconductors and their manufacturing equipment, thin films, materials, chemicals and gases.

Book Description
The processing of semiconductor silicon for manufacturing low cost photovoltaic products has been a field of increasing activity over the past decade and a number of papers have been published in the technical literature. This volume presents comprehensive, in-depth reviews on some of the key technologies developed for processing silicon for photovoltaic applications. It is complementary to Volume 5 in this series and together they provide the only collection of reviews in silicon photovoltaics available.The volume contains papers on: the effect of introducing grain boundaries in silicon; the commercial production for multicrystalline silicon ingots and ribbon; epitaxial solar cell fabrication; metallurgical approaches to producing low-cost meltstock; the non-conventional bifacial solar cell approach.

Book Description
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.

Book Description
This book focuses on crystalline silicon solar cell science and technology. It is written from the perspective of an experimentalist with extensive hands-on experience in modeling, fabrication, and characterization. A practical approach to solar cell fabrication is presented in terms of its three components: materials, electrical, and optical. The materials section describes wafer processing methods including saw damage removal, texturing, diffusion, and surface passivation. The electrical section focuses on formation of ohmic contacts on n and p-doped surfaces. The optical section illustrates light interaction with textured silicon surfaces in terms of geometrical, diffractive and physical optics, transmission, and surface photovoltage (SPV) spectroscopy. A final chapter analyzes performance of solar cells, fabricated with a wide range of process parameters. A brief economic analysis on the merits of crystalline silicon-based photovoltaic technology as a cottage industry is also included./div This professional reference will be an important resource for practicing engineers and technicians working with solar cell and PV manufacturing and renewable energy technologies, as well as upper-level engineering and material science students. Presents a practical approach to solar cell fabrication, and characterization; Offers modular methodology with detailed equipment and process parameters supported by experimental results; Includes processing diagrams and tables for 16% efficient solar cell fabrication.
