Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Department of Energy (DOE) supports research activities in polycrystalline thin films through the Polycrystalline Thin-Film Program at the Solar Energy Research Institute (SERI). This program includes research and development (R & D) in both copper indium diselenide and cadmium telluride thin films for photovoltaic applications. The objective of this program is to support R & D of photovoltaic cells and modules that meet the DOE long-term goals of high efficiency (15%-20%), low cost ($50/m2), and reliability (30-year lifetime). Research carried out in this area is receiving increased recognition due to important advances in polycrystalline thin-film CulnSe2 and CdTe solar cells and modules. These have become the leading thin-film materials for photovoltaics in terms of efficiency and stability. DOE has recognized this potential through a competitive initiative for the development of CuInSe2 and CdTe modules. This paper focuses on the recent progress and future directions of the Polycrystalline Thin-Film Program and the status of the subcontracted research on these promising photovoltaic materials.

This volume includes sixty-eight papers presented at Symposium A, "Amorphous and Polycrystalline Thin-Film Silicon Science and Technology-2011," which took place April 25-29, during the 2011 MRS Spring Meeting in San Francisco, California. The symposium covered the science and technology of thin-film silicon based materials, reviewed recent progress, addressed the scientific and technical issues in the field, and this year, focused sessions were held on the topic of solar cell efficiency.

Book excerpt: This paper presents recent results, status, and future prospects for the US Department of Energy's (DOE's) Polycrystalline Thin Film Photovoltaic program, managed by the Solar Energy Research Institute (SERI). The devices being studied most intensively are heterojunctions based on CuInSe/sub 2/ and on CdTe. Both materials have attained over 10% efficiency in polycrystalline form. The main emphasis is on CuInSe/sub 2/, for which Boeing has reported an 11%-efficient device (AMl ELH simulation). Important work is being done on studies of the composition/electronic properties of CuInSe/sub 2/ and its response to post-deposition annealing. In the CdTe research, ohmic, stable back-contacting and control of p-type doping are being investigated. New efforts to study polycrystalline two-junction stacked cells are underway with two-terminal cells (at IEC) and with four-terminal cells (at SMU). This preliminary work is expected to be expanded, with emphasis on CdTe and other top-cell (high-bandgap) materials. These efforts introduce a number of new research areas (e.g., transparent ohmic contacts to p-CdTe and sub-bandgap light-losses in polycrystalline materials). The aim of the program is to produce stable, high-efficiency (15%), thin-film cells that can be deposited inexpensively by techniques that are scalable to large areas.

Available in PDF, EPUB and Kindle. Book excerpt: This report describes research to fabricate high-efficiency CdZnS/CuInGaSe[sub 2] (CIGS) thin-film solar cells, and to develop improved transparent conductor window layers such as ZnO. A specific technical milestone was the demonstration of an air mass (AM) 1.5 global, 13% efficient, 1-cm[sup 2]-total-area CIGS thin-film solar cell. Our activities focused on three areas. First, a CIGS deposition: system was modified to double its substrate capacity, thus increasing throughput, which is critical to speeding the process development by providing multiple substrates from the same CIGS run. Second, new tooling was developed to enable an investigation of a modified aqueous CdZnS process. The goal was to improve the yield of this critical step in the device fabrication process. Third, our ZnO sputtering system was upgraded to improve its reliability, and the sputtering parameters were further optimized to improve its properties as a transparent conducting oxide. The characterization of the new CIGS deposition system substrate fixturing was completed, and we produced good thermal uniformity and adequately high temperatures for device-quality CIGS deposition. Both the CIGS and ZnO deposition processes were refined to yield a ZnO//Cd[sub 0.82]Zn[sub 0.18]S/CuIn[sub 0.80]Ga[sub 0.20]Se[sub 2] cell that was verified at NREL under standard testing conditions at 13.1% efficiency with V[sub oc] = 0.581 V, J[sub sc] = 34.8 mA/cm[sup 2], FF = 0.728, and a cell area of 0.979 cm[sup 2].
Download or read book Advanced Characterization Techniques for Thin Film Solar Cells written by Uwe Rau and published by John Wiley & Sons. This book was released on 2011-05-25 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written by scientists from leading institutes in Germany, USA and Spain who use these techniques as the core of their scientific work and who have a precise idea of what is relevant for photovoltaic devices, this text contains concise and comprehensive lecture-like chapters on specific research methods. They focus on emerging, specialized techniques that are new to the field of photovoltaics yet have a proven relevance. However, since new methods need to be judged according to their implications for photovoltaic devices, a clear introductory chapter describes the basic physics of thin-film solar cells and modules, providing a guide to the specific advantages that are offered by each individual method. The choice of subjects is a representative cross-section of those methods enjoying a high degree of visibility in recent scientific literature. Furthermore, they deal with specific device-related topics and include a selection of material and surface/interface analysis methods that have recently proven their relevance. Finally, simulation techniques are presented that are used for ab-initio calculations of relevant semiconductors and for device simulations in 1D and 2D. For students in physics, solid state physicists, materials scientists, PhD students in material sciences, materials institutes, semiconductor physicists, and those working in the semiconductor industry, as well as being suitable as supplementary reading in related courses.
Download or read book Silicon Based Thin Film Solar Cells written by Roberto Murri and published by Bentham Science Publishers. This book was released on 2013-03-20 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silicon Based Thin Film Solar Cells explains concepts related to technologies for silicon (Si) based photovoltaic applications. Topics in this book focus on ‘new concept’ solar cells. These kinds of cells can make photovoltaic power production an economically viable option in comparison to the bulk crystalline semiconductor technology industry. A transition from bulk crystalline Si solar cells toward thin-film technologies reduces usage of active material and introduces new concepts based on nanotechnologies. Despite its importance, the scientific development and understanding of new solar cells is not very advanced, and educational resources for specialized engineers and scientists are required. This textbook presents the fundamental scientific aspects of Si thin films growth technology, together with a clear understanding of the properties of the material and how this is employed in new generation photovoltaic solar cells. The textbook is a valuable resource for graduate students working on their theses, young researchers and all people approaching problems and fundamental aspects of advanced photovoltaic conversion.
