Four-year outdoor testing shows perovskite solar cells suffer from high seasonality

Testing conducted by the Helmholtz-Zentrum Berlin (HZB) in Germany has shown that perovskite solar cells operating at high latitudes in Europe may suffer from higher performance losses in winter compared to conventional PV devices. The scientists warned, however, that at lower latitudes this seasonality may be less pronounced. A group of researchers at Germany's Helmholtz-Zentrum Berlin (HZB) has conducted a 4-year outdoor testing of standard perovskite solar cells at one of its facilities in Germany and has found that perovskite-based PV devices may suffer from a higher seasonality compared ...
