Research on Polycrystalline Thin-Film Materials, Cells, and Modules

    Research output: Contribution to conferencePaper


    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 ofphotovoltaic 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 ofefficiency 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.
