This test system is a joint effort of Semprius (Durham, NC) and Siemens in collaboration with the Spanish Institute of Concentration Photovoltaic Systems (ISFOC) and the University of Madrid. Leading modules’ manufacturers of conventional PV technologies achieved the maximum module efficiency of about 20% with monocrystalline PV modules and about 16% with polycrystalline technology
