Halide perovskite, a novel semiconductor material, was initially used in solar cells since 2009, and tremendous progresses have been witnessed in the last decade. The power conversion efficiency of the single perovskite solar cells has been incredibly increased up to 25.2%, and close to 30% efficiency was realized in perovskite/silicon tandem solar cells. Recently, the application of perovskite has been extended to the light-emitting diodes and photo-detectors. Over than 20% external quantum efficiency of electroluminescence in green, red regions and close to 10% efficiency in blue were reported. Moreover it was very encouraged that the white emission based on new physical process were demonstrated. And very sensitive X-ray photo detector has been achieved by several groups. Furthermore, the perovskite memristors has been come true via the ion-migration character of this special material. In one word, halide perovskite is a new and also a wonderful semiconductor material, the optoelectronic devices performance based on this material are very amazing.
