Stacked Perovskite / CIGS Solar Module Achieves Unprecedented Efficiency at 17.8 Percent.

Scientists from Zentrum für Sonnenenergie- und Wasserstoff-Forschung Baden-Württemberg (Centre for Solar Energy and Hydrogen Research, ZSW), Karlsruhe Institute of Technology (KIT) and imec (partner in Solliance and EnergyVille) have fabricated a thin-film solar module stack made up of perovskite and Copper Indium Gallium Selenide (CIGS) with a conversion efficiency of 17.8 percent. For the first time, this tandem module surpasses the highest efficiencies of separate perovskite and CIGS modules.
