New World Record for Concentrator Photovoltaics – 36.7 Percent for New Solar Module Using Highly Efficient Multi-Junction Solar Cells
The Fraunhofer Institute for Solar Energy Systems ISE has been successfully developing concentrator photovoltaic (CPV) technology for many years. In this technology Fresnel lenses are used to bundle sunlight and focus it onto miniature, highly efficient solar cells. The FLATCON® module technology originates from Fraunhofer ISE and is continually under further development at the Institute. Now with their newest CPV module technology, the Freiburg researchers announce a world record module efficiency of 36.7 %, achieved by adapting the concentrating lens to a new solar cell structure. The high module efficiency was measured under Concentrator Standard Testing Conditions, or CSTC, and marks the best value ever achieved for a photovoltaic module.
