Fraunhofer ISE sets two efficiency records for monolithic triple solar cells based on silicon August 29.8.2019, XNUMX - Researchers at the Fraunhofer Institute for Solar Energy Systems ISE have succeeded in further increasing the efficiency of monolithic triple solar cells made from III-V semiconductors and silicon. Thanks to the combination of several absorber materials, these multi-junction solar cells use the solar spectrum significantly better than conventional silicon solar cells. The world record [...]
