A German institute just broke the solar cell efficiency record with 32.5 percentA tandem solar cell developed by researchers at the Helmholtz Zentrum Berlin (HZB) has converted 32.5 percent of incident solar radiation into electrical energy, a world record.There has been significant success when halide perovskites have been used to make solar cells.It was only in late 2021 that HZB broke the previous world record for energy conversion efficiency of the solar cell when it achieved a 29.8 percent conversion.Come summer 2022, Ecole Polytechnique Fédérale de Lausanne in Switzerland broke the 30 percent barrier for energy conversion when it recorded a 31.3 efficiency.With the recent achievement, the record may be back to the HZB, but researchers at other institutes are also pushing the limits of what is possible with solar cells and promising a brighter, greener future for the planet."
