摘要

Perovskite is a magic material with a structure similar to calcium titanate (CaTiO3).Among perovskite materials,halide perovskite has gained consid-erable attention owing to its superior semiconducting properties such as direct band gap and relatively small effective mass of electrons and holes.In recent years,the power conversion efficiency of halide perovskite solar cells has been continuously refreshed.The growth of bulk halide perovskite single crystals (PSCs) has become crucial to the investigation of their intrinsic properties.In the entire preparation process,the growth method gener-ally plays a significant role,which determines the quality and size of the target PSCs.In this review,we summarized the existing mainstream synthetic methods for growing bulk PSCs including solution and solid-phase methods.We discussed the characteristics of these methods and the influence of the growth parameters on the quality and size of the resulting PSCs.Moreover,we briefly introduce the applications of PSCs as semiconductors in photodetectors and gas sensors.Understanding the growth behaviors of PSCs is insightful for future research on their synthesis and applications.
