Experimental Evidence of Localized Shallow States in Orthorhombic Phase of CH3NH3PbI3 Perovskite Thin Films Revealed by Photocurrent Beat Spectroscopy

We demonstrate evidence of localized states near the band edge of lead halide perovskite semiconductor CH3NH3PbI3 thin films. In these films, the high-temperature tetragonal and the low-temperature orthorhombic phases coexist at low temperatures. We determine the exact energy level of the localized...
