Abstract

Metal halide perovskites are a leading contender to disrupt not only terrestrial photovoltaic (PV) markets, but also the proliferating space PV markets. This is due to their impressive power conversion efficiencies, potentially low cost, and adaptability to flexible architectures. Here we assess the stability of three perovskite systems; a mixed Pb-Sn perovskite, and two mixed cation-triple halide systems. In all cases high tolerance to proton irradiation was observed. However, in the case of the mixed Pb-Sn system, irreversible decomposition of the perovskite along with the increased prevalence of defects was observed with thermal cycling. In the case of the mixed cation triple halides remarkable stability was demonstrated, in addition to self-healing, the results of which will be described here.
