Abstract
AbstractThis work investigates the radiation resistance of high‐performance multi‐component perovskite solar cells (PSCs) for the first time under extreme short‐pulse proton irradiation conditions. The devices are subjected to high‐intensity 170 keV pulsed (150 ns) proton irradiation, with a fluence of up to 1013 p cm−2, corresponding to ≈30 years of operation at low Earth orbit. A complex material characterization of the perovskite active layer and device physics analysis of the PSCs before and after short‐pulse proton irradiation is conducted. The obtained results indicate that the photovoltaic performance of the solar cells experiences a slight deterioration up to 20 % and 50 % following the low 2 × 1012 p cm−2 and high 1 × 1013 p cm−2 proton fluences, respectively, due to increased non‐radiative recombination losses. The findings reveal that multi‐component PSCs are immune even to extreme high‐intense short‐pulse proton irradiation, which exceeds harsh space conditions, including intense coronal ejection events usually associated with solar flares.
