Abstract
Investigations of organic-inorganic metal halide perovskite materials have attracted extensive attention due to their excellent properties including bandgap tunability, long charge diffusion length, and outstanding optoelectronic merits. Organic-inorganic metal halide perovskites are demonstrated to be promising materials in a variety of optoelectronic applications including photodetection, energy harvesting, and light-emitting devices. As perovskite solar cells are well studied in literature, here, the recent developments of organic-inorganic metal halide perovskite materials in optoelectronic devices beyond solar cells are summarized. The preparation of organic-inorganic metal halide perovskite films is introduced. Applications of organic-inorganic metal halide perovskite materials in light-emitting diodes, photodetectors, and lasers are then highlighted. Finally, the recent advances in these optoelectronic applications based on organic-inorganic metal halide materials are summarized and the future perspectives are discussed.
