Perovskite solar cells (PSCs) are a promising next-generation photovoltaic (PV) technology for space applications. Their high power-to-weight ratio, mechanical flexibility, and tunable optoelectronic properties make them particularly attractive for Low Earth Orbit (LEO) applications. PSCs demonstrate favorable behavior under low light and partial shading, as well as a unique self-healing response under certain space conditions. They also achieve conventional silicon arrays (0.5-2 W g-1) and 4-6x improvement over III-V multijunction irradiation. The key challenges and opportunities for PSCs in the LEO environment arise from intense ultraviolet radiation, vacuum exposure, thermal cycling, and proton irradiation. In this review, a comprehensive understanding of PSCs in the space environment is presented, including recent strategies to improve efficiency, as well as thermal and mechanical durability, while also addressing performance optimization and space PV analysis. This overview highlights the potential of perovskite photovoltaics for coming decade.
