On the Performance of MAPbI3 in the Space Environment

We show that an encapsulated MAPbI3film has survived the space environment on the International Space Station for a total of approximately 10 months on orbit with little to no chemical degradation. This effort is part of our ongoing efforts to determine the feasibility of MAPbI3-bearing solar cells for space applications. This sample was part of the thirteenth flight of the Materials International Space Station Experiment (MISSE-13), which flew from mid-March,2020 until mid-January,2021. We determined the robustness of the material through the use of transmission spectrophotometry. To our knowledge this report represents the longest known flight in space of a MAPbI3film
