    Abstract

    Soft X-ray exposure effects on CH3NH3PbI3 perovskite in a patterned device sample with a similar structure to solar cells, a promising candidate for X-ray detectors, have been investigated with an X-ray Photoelectron Spectroscopy (XPS) time-dependent measurement method. Our experimental analyses demonstrate compositional change from CH3NH3PbI3 to PbI2 due to evaporation of methylammonium iodide.
