Perovskites were first identified as a viable photovoltaic material only ~10 years ago. Perovskite solar cells have demonstrated promising performance with high specific power and high proton/electron radiation tolerance in space environment [1-3]. Recently, perovskite solar cells have been considered under low intensity and low temperature (LILT) conditions for outer planet space applications . Perovskite solar cells have now reached an efficiency of 25.2% , making it the highest-performing thin-film photovoltaic technology. At the cell level, perovskite photovoltaics have demonstrated 23 kW/kg  (specific mass of 0.043 kg/kW) under terrestrial conditions compared to about 500 W/kg for a typical state-of-practice (SOP) space solar cell. Preliminary assessments of the radiation tolerance suggest perovskites surpass other known photovoltaic materials. Consequently, implementation of perovskite photovoltaics may not need heavy cover glass for radiation protection. Current flexible-blanket solar arrays have roughly 70% of their mass in the photovoltaic blanket (with ~30% in the structure).
