HZB achieved 25.5 percent efficiency record in perovskite-silicon tandem solar cells

German researchers at Helmholtz-Zentrum Berlin für Materialien und Energie (HZB) increased the efficiency of perovskite-silicon tandem solar cells from 23.4 percent to 25.5 percent, »which is the highest published value to date.« At the same time, computational simulations were utilized to investigate light conversion in various device designs with different nanostructured surfaces. This enabled optimization of light management and detailed energy yield analyses, according to the scientists. Marko Jošt, first author of the study and postdoctoral fellow in the HZB team of physicist Steve Albrecht believes »that an efficiency of 32.5 percent can realistically be achieved.«
