The result was confirmed by Germany's Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE). The cell was fabricated through a low-temperature co-evaporation method for the growth of the light-absorbing CIGS semiconductor thin film.Researchers from the Federal Laboratories for Materials Science and Technology (EMPA), in Switzerland, claim to have achieved a world record efficiency of 21.38% for a flexible copper, indium, gallium and selenium (CIGS) solar cell on polyimide plastic film. The result was confirmed by Germany's Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE). ...Den vollständigen Artikel lesen ...
