Charge Transport in Halide Perovskite Single Crystals: Experimental and Theoretical Perspectives

Abstract Halide perovskite materials feature strong optical absorption, light carrier masses and, as a consequence, high charge‐carrier mobility, making them one of the candidates for next‐generation optoelectronic devices. This interesting class of materials exhibits unconventional properties that cannot be readily rationalized by traditional concepts. In this regard, single‐crystals of halide perovskites represent an ideal test bench to better understand the intrinsic properties of the material, building the foundation for further investigations of polycrystalline films and related nanoarchitectures. In this Minireview, we analyze charge carrier transport in organic halide perovskite single crystals, summarizing the current literature insights on this matter from theoretical and experimental perspectives.
