Book excerpt: The Polycrystalline Thin Film Solar Cells Program, part of the United States National Photovoltaic Program, performs R D on copper indium diselenide and cadmium telluride thin films. The objective of the Program is to support research to develop cells and modules that meet the US Department of Energy's long-term goals by achieving high efficiencies (15%-20%), low-cost ($50/m2), and long-time reliability (30 years). The importance of work in this area is due to the fact that the polycrystalline thin-film CuInSe2 and CdTe solar cells and modules have made rapid advances. They have become the leading thin films for PV in terms of efficiency and stability. The US Department of Energy has increased its funding through an initiative through the Solar Energy Research Institute in CuInSe2 and CdTe with subcontracts to start in Spring 1990. 23 refs., 5 figs.

This book was released on 2020-09-17 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polycrystalline thin-film solar cells have reached a levelized cost of energy that is competitive with all other sources of electricity. The technology has significantly improved in recent years, with laboratory cell efficiencies for cadmium telluride (CdTe), perovskites, and copper indium gallium diselenide (CIGS) each exceeding 22 percent. Both CdTe and CIGS solar panels are now produced at the gigawatt scale. However, there are ongoing challenges, including the continued need to improve performance and stability while reducing cost. Advancing polycrystalline solar cell technology demands an in-depth understanding of efficiency, scaling, and degradation mechanisms, which requires sophisticated characterization methods. These methods will enable researchers and manufacturers to improve future solar modules and systems.

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.

Book excerpt: The Module Development Initiative has made significant progress in support of the Polycrystalline Thin-Film Program in the past year, and results are presented in this paper. The major U.S. industrial participants in the CulnSe2 portion of this initiative include Siemens Solar Industries, Solarex Corporation, International Solar Electric Technology (ISET), Martin Marietta, and Boeing Aerospace and Electronics. Photon Energy and Solar Cells Inc. are involved in the CdTe research under this initiative. A program is also being addressed for the aggressive development of the thin silicon film on ceramic substrates by AstroPower. The major players in polycrystalline thin films outside of the United States are BP Solar in the United Kingdom, Matsushita Battery in Japan, and Microchemistry in Finland. All three of these groups are developing thin-film CdTe power modules. Additionally, as part of the Photovoltaics for Utility-Scale Applications (PVUSA) project, several emerging thin-film technologies are planned for field testing at Davis, California, during 1992. This paper will summarize the current status and technical results under the subcontracted research in the PVUSA program. In addition, the NREL-funded competition for university research subcontracts will be discussed.

Book excerpt: This paper describes the recent technological advances in polycrystalline thin-film solar cells and modules. Three thin film materials, namely, cadmium telluride (CdTe), copper indium diselenide (CuInSe2, CIS) and silicon films (Si-films) have made substantial technical progress, both in device and module performance. Early stability results for modules tested outdoors by various groups worldwide are also encouraging. The major global players actively involved in the development of the these technologies are discussed. Technical issues related to these materials are elucidated. Three 20-kW polycrystalline thin-film demonstration photovoltaic (PV) systems are expected to be installed in Davis, CA in 1992 as part of the Photovoltaics for Utility-Scale Applications (PVUSA) project. This is a joint project between the US Department of Energy (DOE), Pacific Gas and Electric (PG & E), Electric Power Research Institute (EPRI), California Energy Commission (CEC), and a utility consortium.

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.
