Book Synopsis Experimental Studies of Light-Induced Changes in Long-Ranged Disorder in Amorphous Silicon by :
Download or read book Experimental Studies of Light-Induced Changes in Long-Ranged Disorder in Amorphous Silicon written by and published by . This book was released on 2004 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: The principal objective of the proposed research is the experimental study and elucidation of the role that long-ranged disorder plays in the light-induced metastable conductance changes in hydrogenated amorphous silicon (a-Si:H). The development of sources of low-cost renewable electrical energy is a high national priority. A consensus has developed that a-Si:H is the material of choice for large-area photovoltaic devices. However, the efficiency of a-Si:H-based solar cells decreases by nearly a factor of two following extended illumination, owing to the creation of light-induced defects resulting from the recombination of photo-excited charge carriers. If this light-induced defect formation could be reduced or eliminated, the practical conversion-efficiency of a-Si:H-based solar cells would effectively double, yielding cost per kilowatt-hour values comparable to that of conventional fossil fuel generation of electricity. Recent experimental results and theoretical calculations indicate that associated with light-induced dangling-bond creation, there are alterations in the medium- and long-ranged disorder in the a-Si:H films. A determination of whether or not the long-ranged disorder is affected in the Staebler-Wronski effect is important, for if so, then even when local defect generation is prevented, there could still remain metastable conductance changes that would affect photovoltaic device performance. Alternatively, if experimental studies clearly rule out light-induced changes in the long-ranged order in the a-Si:H film, then entire classes of models for the Staebler-Wronski effect can be eliminated from consideration. The results from this project indicate that the metastable conductance changes associated with the Staebler-Wronski effect can be understood solely in terms of models that involve only local changes in bonding coordination. Attempts to understand or control this phenomenon by altering the long-ranged disorder will not be fruitful.

Book Synopsis Advanced Characterization Techniques for Thin Film Solar Cells by : Daniel Abou-Ras
Download or read book Advanced Characterization Techniques for Thin Film Solar Cells written by Daniel Abou-Ras and published by John Wiley & Sons. This book was released on 2016-07-13 with total page 760 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book focuses on advanced characterization methods for thin-film solar cells that have proven their relevance both for academic and corporate photovoltaic research and development. After an introduction to thin-film photovoltaics, highly experienced experts report on device and materials characterization methods such as electroluminescence analysis, capacitance spectroscopy, and various microscopy methods. In the final part of the book simulation techniques are presented which are used for ab-initio calculations of relevant semiconductors and for device simulations in 1D, 2D and 3D. Building on a proven concept, this new edition also covers thermography, transient optoelectronic methods, and absorption and photocurrent spectroscopy.

Book Synopsis Properties and Applications of Amorphous Materials by : M.F. Thorpe
Download or read book Properties and Applications of Amorphous Materials written by M.F. Thorpe and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this NATO ASI has been to present an up-to-date overview of current areas of interest in amorphous materials, with particular emphasis on electronic properties and device applications. In order to limit the material to a manageable amount, the meeting was concerned almost exclusively with semiconducting materials. This volume should be regarded as a follow-on to the NATO ASI held in Sozopol, Bulgaria in 1996 and published as "Amorphous Insulators and Semiconductors" edited by M.F. Thorpe and M.1. Mitkova (Kluwer Academic Publishers, NATO ASI series, 3 High Technology - Vol. 23). The lectures and seminars fill the gap between graduate courses and research seminars. The lecturers and seminar speakers were chosen as experts in their respective areas, and the lectures and seminars that were given are presented in this volume. During the first week of the meeting, an emphasis was placed on introductory lectures while the second week focused more on research seminars. There were two very good poster sessions that generated a lot of discussion, but these are not reproduced in this volume as the editors wanted to have only larger contributions to make the proceedings more coherent.
Book Synopsis Hydrogen in Semiconductors by : M. Stutzmann
Download or read book Hydrogen in Semiconductors written by M. Stutzmann and published by Elsevier. This book was released on 2012-12-02 with total page 598 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrogen on semiconductor surfaces has been an area of considerable activity over the last two decades. Structural, thermal, and dynamical properties of hydrogen chemisorbed on crystalline silicon and other semiconductors have been studied in great detail. These properties serve as a reference for related, but more complex systems such as hydrogen at multiple vacancies in crystalline semiconductors or at microvoids in amorphous samples. Interesting from a surface physics point of view is the fact that hydrogen as a monovalent element is an ideal terminator for unsaturated bonds on surfaces and therefore tends to have a large influence on surface reconstruction. A related phenomenon with large technological impact (for example in low cost solar cells) is the passivation of grain boundaries in microcrystalline semiconductors. Finally, hydrogenated semiconductor surfaces always appear as a boundary layer during low-energy hydrogenation of bulk semiconductors, so that a complete description of hydrogen uptake or desorption necessarily has to take these surfaces into account. This collection of invited and contributed papers has been carefully balanced to deal with amorphous and crystalline semiconductors and surfaces and presents basic and experimental work (basic and applied) as well as theory. The resulting volume presents a summary of the state-of-the-art in the field of hydrogen in semiconductors and will hopefully stimulate future work in this area.
