Abstract
We report the first successful long duration space flight of perovskite-based photovoltaic devices. These results emphasize that metal-halide perovskite (MHP) solar cells can be packaged adequately for space missions, affirming that space stressors can be managed as theorized. In support of NASA's Artemis program with the goal of a sustained human-lunar presence, there is a need for very large and high-voltage-capable solar arrays. Perovskite-based thin-film photovoltaics offer substantial advantages over state-of-the-art solar arrays from the perspective of manufacturing large arrays. Perovskites have also demonstrated some of the lowest temperature coefficients and highest defect tolerance, which make them excellent candidates for aerospace applications. However, MHPs must demonstrate durability in space which presents different challenges than terrestrial operating environments. To decisively test the viability of perovskites being used in space, a suite of perovskite based photovoltaic devices are positioned in low earth orbit for 9 months on the International Space Station, which was the first long-duration study of an MHP in space. We report significant electrical performance upon return, with a champion device 76% remaining PCE post flight. This is the first successful long duration space flight of perovskite-based photovoltaic devices.
