Progress on growth of metal halide perovskites by vapor-phase synthesis and their applications

Abstract

Abstract Metal halide perovskites (MHPs) show excellent optoelectronic properties and exhibit great potential applications in optoelectronic devices, such as solar cells (SCs), photodetectors, light-emitting diodes (LEDs), lasers, and so on. Vapor-phase synthesis provides an important way to grow large-scale, high-quality MHP thin films and micro-/nanostructures, exhibiting wide applications in constructing all kinds of optoelectronic devices. In this review, we systematically summarize the growth of perovskite thin film and the nano-/microstructure by vapor-phase synthesis. The detailed classification of vapor-phase synthesis is first introduced, and the effects of the substrates on the growth process are discussed subsequently. Then, the applications of perovskite thin films and micro-/nanostructures grown by vapor-phase synthesis in SCs, photodetectors, LEDs, lasers, and so forth, are discussed in detail. Finally, the conclusions and outlook are presented.
