Soft X-ray irradiation effect on surface structure of CH3NH3PbI3 perovskite in multi-film stack device

Soft X-ray exposure effects on CH 3 NH 3 PbI 3 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 analyse...

Description
Summary:Soft X-ray exposure effects on CH 3 NH 3 PbI 3 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 CH 3 NH 3 PbI 3 to PbI 2 due to evaporation of methylammonium iodide.
