Perovskite solar cells are a candidate for use as space solar cells, and their radiation response is studied here for the first time. Perovskite solar cells are fabricated on a quartz substrate to prevent substrate degradation, which might otherwise affect the evaluation of radiation tolerance of the cells. As a result, superior radiation tolerance of perovskite solar cells is indicated from the comparison of output performance of the cells before and after 1-MeV electron irradiation with fluence as high as 1 × 10 16 cm -2 . The short-circuit current, open-circuit voltage, and external quantum efficiency do not deteriorate under electron irradiation. These results suggest that perovskite solar cells are likely to be useful for space application.
