The world of today must face up to two contradictory energy problems: on the one hand, there is the sharply growing consumer demand in countries such as China and India. On the other hand, natural resources are dwindling. Moreover, many of those countries which still possess substantial gas and oil supplies are politically unstable. As a result, renewable natural energy sources have received great attention. Among these, solar-cell technology is one of the most promising candidates. However, there still remains the problem of the manufacturing costs of such cells. Many attempts have been made to reduce the production costs of “conventional” solar cells (manufactured from monocrystalline silicon using diffusion methods) by instead using cheaper grades of silicon, and simpler pn-junction fabrication. That is the ‘hero’ of this book; the heterojunction solar cell.
This comprehensive, detailed treatise on the physics and applications of the new emerging technology of amorphous semiconductors focuses on specific device research problems such as the optimization of device performance. The first part of the book presents hydrogenated amorphous silicon type alloys, whose applications include inexpensive solar cells, thin film transistors, image scanners, electrophotography, optical recording and gas sensors. The second part of the book discusses amorphous chalcogenides, whose applications include electrophotography, switching, and memory elements. This book will serve as an excellent reference source for solid state scientists and engineers, and as a useful self-contained introduction to the field for graduate students.

With contributions by numerous experts
This book, first published in 2001, provides an international forum to exchange research results on topics ranging from silicon thin-film physics and chemistry, to novel device design and engineering. It covers all aspects of hydrogenated amorphous silicon (a-Si:H) science and technology, and is the fourth consecutive volume in the series to cover heterogeneous silicon film materials, including the nanocrystalline, microcrystalline, and polycrystalline films. A special 'Millennium Session' celebrating the most important achievements of the last three decades in the field of amorphous and microcrystalline silicon thins films, is featured. Topics include: amorphous film growth and properties; nanocrystalline/microcrystalline film growth and properties; ordering, ordering transitions and photocrystalline films: polycrystalline films, epitaxial growth and properties; catalytic/hot-wire CVD - amorphous to polycrystalline films; implantation, annealing and crystallization; structure and hydrogen; band, band tails and defect states; metastability and equilibration; thin-film transistors, displays and imagers; thin-film solar cells and solar-cell structures; amorphous silicon detectors and other devices; and heterogeneous silicon transport and device applications.
This book gives the first systematic and complete survey of technology and application of amorphous silicon, a material with a huge potential in electronic applications. The book features contributions by world-wide leading researchers in this field.
