Abstract

Organic–inorganic hybrid perovskites such as methylammonium lead halide (CH3NH3PbI3) have been employed in photoelectronic device applications such as light-emitting diodes, solar cells, field-effect transistors, and photodetectors. Combining ultraviolet photoemission spectroscopy(UPS), X-ray photoemission spectroscopy (XPS), atomic force microscopy(AFM), X-ray diffraction measurements (XRD), and device fabrication and characterization, we performed a systematic investigation on the correlation of energy level alignment, film growth and molecular orientation of a number of interfaces and their modifications in photodetectors based on CH₃NH₃PbI₃ and FA_0.4MA_0.6PbI₃.
