Single-crystal halide perovskites: Opportunities and challenges

Single-crystal halide perovskites have received growing attention due to their high carrier-transport efficiency and excellent stability in comparison with polycrystalline counterparts. This review is timely, since it gives a comprehensive overview of the advances single-crystal perovskite, including unique physical properties, controllable crystal growth, and, most importantly, device applications. In end, we share our perspectives on remaining challenges potential solutions for driving this emerging field forward. will provide food thought researchers jump-start beginners who want join exciting field. demonstrated optoelectronic properties promising application potentials, thanks remarkable carrier dynamics, solution processing procedures, outstanding stabilities. The latest progress future are reviewed herein. basic fundamental studies first discussed. We then introduce growth methods these materials summarize recent developments. further present perovskite devices among major fields. Finally, discuss current some suggestions development. hope paper can help readers understand status perovskites.
