Perovskite solar cells hold great promise for space applications due to their exceptional properties, including high power-to-weight ratios and efficiencies comparable to silicon cells. Their solution processability lowers both manufacturing and launch costs, presenting a cost-effective alternative to gallium arsenide cells. However, their viability in space is challenged by harsh conditions such as high vacuum, extreme temperatures, and radiation. This study investigates the impact of extreme temperature fluctuations in low Earth orbit, ranging from -100*C to +100*C, on perovskite solar cell performance. Operando GIWAXS measurements enable real-time analysis of the crystal structure under simultaneous illumination and thermal cycling. Measurements of I-V curves and optical absorption spectra further assess electrical and optical properties. Results reveal temperature-dependent efficiency variations and degradation influenced more by device layers and interfaces than the active layer itself. Understanding the mechanical, optical, and electrical behavior of the entire cell assembly under such conditions is key to optimizing durability and performance.
