Heliatek’s R&D teams reached a record conversion efficiency of 13.2% for an OPV multi-junction cell, setting a new world record for the direct conversion of sunlight into electricity using organic photovoltaic cells. The measurement was independently confirmed by Fraunhofer CSP.   Due to the low light and high temperature behavior of the organic semiconductor, the electricity generation of the newly developed cells corresponds to the output of conventional solar cells with 16% to 17% effic...
