Charge Transport Properties of Methylammonium Lead Trihalide Hybrid Perovskite Bulk Single Crystals

Abstract

In the past decade, hybrid halide perovskites have been discovered as promising intrinsic semiconductors for applications in many optoelectronics areas such as photovoltaics, photodetectors, lasers, and transistors. Herein, the major focus is the charge transport properties of MAPbBr3 and MAPbI3 bulk single‐crystal hybrid perovskites, starting by providing the relevant historical and scientific background information and then presenting a detailed synopsis of the methods to synthesize crystals. Following this, the core properties of crystals including charge transport properties are analyzed and discussed. A small critique of the space‐charge‐limited current method, which is one of the major methods to analyze charge transport properties, is given, before the applications of hybrid perovskite crystals are discussed, largely focusing on solar cells, radiation detectors, lasers, and other thermoelectric applications. An outlook as to the future of these materials is also presented with the conclusion.
