Abstract

A hybrid light/ToF-SIMS system was used to analyze the dynamic chemical changes of perovskite CH₃NH₃PbI₃ films under light illumination, in order to reveal the mechanism of light instability for perovskite materials. Real-time material degradation and quasi-reversible iodine migration were successfully observed.
