Available in PDF, EPUB and Kindle. Book excerpt: Presented at the 2001 NCPV Program Review Meeting: High-quality high-deposition-rate (10 angstrom/s) a-SiGe:H alloy solar cells have been made by hot-wire chemical-vapor deposition. High-quality high-deposition-rate (10 Å/s) amorphous silicon germanium (a-SiGe:H) alloy solar cells have been made by hot-wire chemical-vapor deposition (HWCVD). HW a-SiGe:H alloys are evaluated in the SS/n-i-p/ITO solar cell configuration, where the n- and i-layers are deposited by HWCVD at NREL and the p-layer by conventional glow discharge in a separate reactor by United Solar. Effects of Ge concentration, hydrogen dilution, substrate temperature, and step-wise bandgap profile in the i-layer have been studied and optimized. The best cell has an average optical bandgap of 1.6 eV with a low H-dilution at 250 C and a 3-stepwise bandgap profile where the narrowest bandgap is near the p-i interface. The best initial power output has exceeded 4 mW/cm2 under AM 1.5 illumination with a [lambda]>530-nm filter. When combining with a USSC a-Si:H top solar cell, the best double-junction solar cell exhibits an initial 11.7% active-area efficiency, and a 9.6% stable efficiency after 1000 hours of one-sun light soaking.

Book excerpt: Discussing methods for maximizing available energy, Energy Conversion surveys the latest advances in energy conversion from a wide variety of currently available energy sources. The book describes energy sources such as fossil fuels, biomass including refuse-derived biomass fuels, nuclear, solar radiation, wind, geothermal, and ocean, then provides the terminology and units used for each energy resource and their equivalence. It includes an overview of the steam power cycle, gas turbines, internal combustion engines, hydraulic turbines, Stirling engines, advanced fossil fuel power systems, and combined-cycle power plants. It outlines the development, current use, and future of nuclear fission. The book also gives a comprehensive description of the direct energy conversion methods, including, Photovoltaics, Fuel Cells, Thermoelectric conversion, Thermionics and MHD It briefly reviews the physics of PV electrical generation, discusses the PV system design process, presents several PV system examples, summarizes the latest developments in crystalline silicon PV, and explores some of the present challenges facing the large scale deployment of PV energy sources. The book discusses five energy storage categories: electrical, electromechanical, mechanical, direct thermal, and thermochemical and the storage media that can store and deliver energy. With contributions from researchers at the top of their fields and on the cutting edge of technologies, the book provides comprehensive coverage of end use efficiency of green technology. It includes in-depth discussions not only of better efficient energy management in buildings and industry, but also of how to plan and design for efficient use and management from the ground up.

Available in PDF, EPUB and Kindle. Book excerpt: Brought to you by the creator of numerous bestselling handbooks, the Handbook of Energy Efficiency and Renewable Energy provides a thorough grounding in the analytic techniques and technological developments that underpin renewable energy use and environmental protection. The handbook emphasizes the engineering aspects of energy conservation and renewable energy. Taking a world view, the editors discuss key topics underpinning energy efficiency and renewable energy systems. They provide content at the forefront of the contemporary debate about energy and environmental futures. This is vital information for planning a secure energy future. Practical in approach, the book covers technologies currently available or expected to be ready for implementation in the near future. It sets the stage with a survey of current and future world-wide energy issues, then explores energy policies and incentives for conservation and renewable energy, covers economic assessment methods for conservation and generation technologies, and discusses the environmental costs of various energy generation technologies. The book goes on to examine distributed generation and demand side management procedures and gives a perspective on the efficiencies, economics, and environmental costs of fossil and nuclear technologies. Highlighting energy conservation as the cornerstone of a successful national energy strategy, the book covers energy management strategies for industry and buildings, HVAC controls, co-generation, and advances in specific technologies such as motors, lighting, appliances, and heat pumps. It explores energy storage and generation from renewable sources and underlines the role of infrastructure security and risk analysis in planning future energy transmission and storage systems. These features and more make the Handbook of Energy Efficiency and Renewable Energy the tool for designing the energy sources of the future.

This book was released on 2003-11-12 with total page 824 pages. Available in PDF, EPUB and Kindle. Book excerpt: Amorphous silicon technology has been the subject of symposia every year since 1984. This remarkable longevity is due to the continuous emergence of new scientific questions and new technological challenges for silicon thin films. Earlier there was a strong emphasis on methods to achieve high deposition rates using plasma or hot-wire chemical vapor deposition, and on the properties and applications of nanocrystalline silicon films, which for example have been incorporated into stacked a-Si:H/nc-Si:H solar cells. The papers appearing in this book are sorted under six chapter headings on the basis of subject matter. Chapter I is concerned with amorphous network structures, electronic metastability, defects, and photoluminescence. Chapter II focuses on thin-film transistors and imager arrays. Chapter III covers solar cells. Chapter IV addresses growth mechanisms, hot-filament CVD, and nc-Si:H growth. Chapter V contains all remaining topics in film growth, especially those related to devices. Finally, Chapter VI focuses on crystallized film.
