Perovskite solar cell performance shows seasonal variation in long-term field test

Berlin, Germany (SPX) Jul 25, 2025

In a multi-year outdoor study, researchers at Helmholtz-Zentrum Berlin (HZB) have uncovered significant seasonal performance fluctuations in perovskite solar cells. Conducted on the rooftop of the Adlershof campus, the long-term experiment exposed various solar technologies to natural weather conditions, focusing in particular on perovskite cells known for their high lab efficiencies and low pro
