Effects of chlorine addition to perovskite-type CH3NH3PbI3 photovoltaic devices
2016
Journal of the Ceramic Society of Japan
Effects of PbCl 2 addition to perovskite CH 3 NH 3 PbI 3 precursor solutions on the photovoltaic properties were investigated. TiO 2 / CH 3 NH 3 PbI 3¹x Cl x -based photovoltaic devices were fabricated, and the microstructures of the devices were investigated by X-ray diffraction. The structure analysis indicated phase transformation of the perovskite structure from cubic to tetragonal system by chlorine (Cl)-doping. External and internal quantum efficiencies were improved by a small amount of
