Analysis of Performance Decay in Harsh Space Environment of Perovskite Solar Cell

Photovoltaic devices employed in extraterrestrial environments encounter high-energy particles and ionizing radiation that compromise their stability, intensifying lattice defects. This study presents a theoretical investigation into the radiation durability of perovskite based solar cells for prospective use in space missions. We simulated the structural damage caused by proton exposure on perovskite cells operating in lunar orbit. A defect-based degradation model was utilized to replicate the radiation induced performance loss, accurately reflecting experimental observations such as a marked drop in short circuit current (J _SC ) and a slight reduction in open circuit voltage (V _OC ) under 1 MeV proton fluence. The simulation outcomes confirm the strong radiation endurance of perovskite materials, which maintain stable photovoltaic performance even at proton fluence levels up to 10 ¹³ particles/cm ² . These simulation derived results validate the applicability of perovskite solar cells in extraterrestrial environments.
