Book Description
This book offers a bird’s-eye view of the recent development trends in photovoltaics – a big business field that is rapidly growing and well on its way to maturity. The book describes current efforts to develop highly efficient, low-cost photovoltaic devices based on crystalline silicon, III–V compounds, copper indium gallium selenide (CIGS) and perovskite photovoltaic cells along with innovative, cost-competitive glass/ flexible tubular glass concentrator modules and systems, highlighting recent attempts to develop highly efficient, low-cost, flexible photovoltaic cells based on CIGS and perovskite thin films. This second edition presents, for the first time, the possible applications of perovskite modules together with Augsburger Tubular photovoltaics.

Book Description
We use a high-throughput (combinatorial) hot-wire chemical vapor deposition system to passivate the crystal silicon surface and to grow heterojunction silicon solar cells. We study the effectiveness of crystal surface treatments by atomic H or/and NHx radicals, followed by the growth of thin hydrogenated amorphous silicon (a Si:H) films. Treatment and layer properties such as times, thicknesses, and gas mixtures can be continuously graded, creating a two-dimensional sample with each variable varying in one direction. This results in high-throughput optimization of the processes. Effective carrier lifetime is measured by photoconductive decay to evaluate the effectiveness of the surface passivation by surface treatments. The effective carrier lifetime increases from about 5 [micro]s without passivation to about 24 [micro]s with an optimized surface treatment and thickness a-Si:H on single-sided c-Si. Transmission electron microscopy reveals that a-Si:H, a mixed phase, or epitaxial growth of thin-film Si depending on the surface treatment. Improvement in effective carrier lifetime correlates with an immediate a-Si:H growth on c-Si, rather than a mixed phase and epitaxial Si growth. We have obtained an efficiency of 13.4% on a non-textured single-sided heterojunction solar cell on p-type CZ-Si processed with optimized surface treatment.

Book Description
Low temperature processes for semiconductors have been recently under intensive development to fabricate controlled device structures with minute dimensions in order to achieve the highest device performance and new device functions as well as high integration density. Comprising reviews by experts long involved in the respective pioneering work, this volume makes a useful contribution toward maturing the process of low temperature epitaxy as a whole.

Book Description
This book provides an overview of chemical vapor deposition (CVD) methods and recent advances in developing novel materials for application in various fields. CVD has now evolved into the most widely used technique for growth of thin films in electronics industry. Several books on CVD methods have emerged in the past, and thus the scope of this book goes beyond providing fundamentals of the CVD process. Some of the chapters included highlight current limitations in the CVD methods and offer alternatives in developing coatings through overcoming these limitations.

Book Description
The main focus of the present work is related to the optimization of heterojunction solar cells. The key roles in obtaining high efficient heterojunction solar cells are mainly the plasma enhanced chemical vapor deposition of very low defect layers, and the sufficient surface passivation of all interfaces. In heterojunction solar cells, the a-Si: H/c-Si hetero-interface is of significant importance, since the hetero-interface characteristics directly affect the junction properties and thus solar cell efficiency. In this work, the deposition and film properties of various hydrogenated amorphous silicon alloys, such as a-SiC: H, a-SiO_x: H, and muc-Si: H (standard a-Si: H is used as reference), are employed. Special attention is paid to (i) the front and back surface passivation of the bulk material by high-quality wide-gap amorphous silicon suboxides (a-SiO_x: H), and (ii) the influence of wide-gap high-quality a-Si- and muc-Si-based alloys for use as emitter and back-surface-

Book Description
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.
