AIST-NREL Concentrator Photovoltaic (CPV) Demonstration: Cooperative Research and Development Final Report, CRADA Number CRD-10-402

The purpose of the project is to demonstrate and quantitatively compare performance of CPV systems installed in Japan and installed in the United States. The deployment conditions (e.g. spectrum and temperature) are site dependent and the optimal design of the system may vary with location. The CPV systems will use multi-junction concentrator cells for the conversion of sunlight into optimal design of the cell may depend on the location at which a CPV system is installed. Thus, the systems in Japan and in the US will all use a combination of concentrator cells obtained from three different vendors. This CRADA pertains only to the equipment that will be installed in the US. This effort is a collaborative project between AIST and NREL.
