Abstract

Abstract Perovskite solar cells (PSCs) have drawn significant attention because of high power conversion efficiency, solution processability, large-area device fabrication and low cost. Recently, PSCs have been considered as a promising candidate for the power source of the spacecrafts and satellites in space missions due to their high specific power and cosmic radiation resistance. Herein, we review the main challenges for achieving space-grade perovskite solar cells: light instability, thermal cycling stress and high vacuum-induced issues, as well as the technical advantages with respect to ultra-lightweight, radiation tolerance and upscaling potential. Finally, an outlook on the future development is presented.
