摘要
Lead halide based organic–inorganic hybrid perovskite (HPVK) materials combine the advantages of solution processing, high absorption coefficient, long charge diffusion length, and high mobility of inorganic framework. The recent interest in this field is mainly focused on solution-processable HPVK for energy conversion and different types of optoelectronics. The performance of HPVK optoelectronics is rivaling now that of conventional devices, but the stability of the HPVK device is now a major challenge in the field where chemists are expected to play more active roles. This Perspective summarizes the progress in the understanding of mechanism of the HPVK formation, and various applications in different fields such as solar cells, light-emitting diodes, lasers, photodetectors, and field-effect transistors. A personal view of the past developments and future challenges is also provided.
