Book Description
Today’s solar cell multi-GW market is dominated by crystalline silicon (c-Si) wafer technology, however new cell concepts are entering the market. One very promising solar cell design to answer these needs is the silicon hetero-junction solar cell, of which the emitter and back surface field are basically produced by a low temperature growth of ultra-thin layers of amorphous silicon. In this design, amorphous silicon (a-Si:H) constitutes both „emitter“ and „base-contact/back surface field“ on both sides of a thin crystalline silicon wafer-base (c-Si) where the electrons and holes are photogenerated; at the same time, a-Si:H passivates the c-Si surface. Recently, cell efficiencies above 23% have been demonstrated for such solar cells. In this book, the editors present an overview of the state-of-the-art in physics and technology of amorphous-crystalline heterostructure silicon solar cells. The heterojunction concept is introduced, processes and resulting properties of the materials used in the cell and their heterointerfaces are discussed and characterization techniques and simulation tools are presented.

Book Description
This book from the highly successful series on amorphous-silicon science and devices reflects the increasing range of applications for a-Si technology. Advances in solar cells incorporating microcrystalline silicon absorber layers are discussed, and a new manufacturing facility for amorphous-silicon-based tandem solar cells is highlighted. Progress towards realizing both higher resolution and improved visibility in active-matrix liquid crystal displays is featured. And while work on raising the deposition rate for amorphous-silicon transistors is also outlined, it is expected that advances in devices and manufacturing will be accelerated when several fundamental puzzles regarding amorphous silicon's structure and optoelectronic properties are resolved. Topics include: solar cells; thin-film transistors and flat-panel displays; sensors, detectors and novel devices; device physics; deposition technologies; studies of growth processes; hydrogen and structure a-Si:H; defects and equilibration in a-Si:H; fundamental issues in defect processes; transport and recombination processes; thin films for photovoltaic and related device applications.

Book Description
This book celebrates 20 years of MRS symposia on the topic of amorphous silicon. Contributors showed that the simplified theories developed to explain the limited experimental information available in the early eighties have spurred more sophisticated experimentation - either refining the early understanding or making it irrelevant. The differences of opinion that continue to exist and emerge are probably the hallmark of the amazing vitality of this field. Applications range from 'mature' thin-film transistors, solar cells and image sensors, to the 'emerging' possibility of erbium-doped nanocrystalline silicon-based materials for lasers and amorphous silicon quantum dots for luminescent devices. The book discusses material characterization, growth processes and devices. Each chapter is further subdivided into sections that group papers around common themes. Topics include: nanomaterials; electronic structure; metastable effects; understanding of growth processes; laser-induced crystallization; metal-induced crystallization; other growth techniques; newer devices; solar cells and thin-film transistors.

Hydrogen in Semiconductors
Author: Norbert H. Nickel
Publisher:
ISBN:
Category : Science
Languages : en
Pages : 216
Book Description
The study of hydrogen in solids is of significant importance in modern technology. Often present in large concentrations by various growth techniques, hydrogen affects the structural, electronic, and optical properties of crystals. Isolated hydrogen is often electrically active, causing passivation or charge compensation of defects and impurities. Since the presidential proposal of the Freedom Car, hydrogen in semiconductors takes another twist as a potential source of clean fuel for the future. The study of hydrogen transport, diffusion, and chemical reaction in solids is, therefore, of significant social importance. But as often happens in science, different groups of researchers studying hydrogen in solids do not always speak the same language. For example, few people would consider silicon as a practical fuel storage material due to its weight, but in reality, aluminum hydrides have been seriously considered for such a purpose. The knowledge acquired in the last half century for hydrogen in conventional semiconductors has not been effectively transferred to the study of hydrogen storage in emerging semiconductors such as carbon nanotubes. This volume brings together scientists from various research areas to encourage cross fertilization and wider dissemination of the advances in this important field of study. Highlights include recent developments in the understanding of light-induced metastability in amorphous silicon, hydrogen in zinc oxide as a means of n-type doping, and hydrogen doping of dilute nitrides that modifies the bandgap in some rather surprising ways. Hydrogen interaction with donors and acceptors is a never-ending story that is also featured here. Topics include: hydrogen in elemental semiconductors; hydrogen in oxides; and general properties of hydrogen in semiconductors.
