Semprius' novel microcell based high-concentration photovoltaic design has a concentration of >1100X and an externally validated efficiency of 33.9% at standard test condition. The design approach enables substrate reuse, short optical path, unique low-cost two-stage refractive optics, zero-cost thermal management, improved reliability and a highly scalable, massively parallel manufacturing process. Module characterization and on-sun results from a 3.5 kW research, development and demonstration system at the Instituto de Sistemas Fotovoltaicos de Concentracion, Spain are presented.
