The Photovoltaic (PV) Projects at Sandia National Laboratories support the Department of Energy (DOE) National Photovoltaics Program through silicon solar cell research and development, concentrator module research and development, evaluation of cells and modules for both one‐sun and concentrator applications, development and evaluation of hardware for PV applications, and domestic and international applications identification and verification. In all of these activities, close ties are maintained with industry to assure that the U.S. PV industry benefits from the Sandia/DOE effort. These industry ties include collaborative agreements between industrial partners and Sandia to improve fabrication processes, evaluating industry components and prototype products for performance and reliability, direct funding of industry for process and product development, and assuring that industry and users are brought together when systems are being developed for new applications. This paper offers an overview of the Sandia Photovoltaic Projects and their contributions to this effort.
