Abstract
Recently, perovskite nanocrystals (NCs) have become highly promising materials due to their unique optical and electrical properties such as high absorption coefficient, high photoluminescence quantum yield, and long exciton diffusion length.

The environmental perception of humans has a profound impact in understanding the natural world as well as the production and life
Inorganic semiconductor material systems, including Si, II–VI and III–V compounds, have been suitably applied in the field of commercial photodetectors[1,2,3] at the initial stage of photodetectors, Si, GaN, and other material systems are significantly dependent on chemical vapor deposition and photolithography
We summarize the latest progress in the synthesis of perovskite NCs, its passivation after synthesis, and its role in photodetectors
Summary
The environmental perception of humans has a profound impact in understanding the natural world as well as the production and life. Low-temperature crystallinity and the solution process are the foundation for the construction of flexible multifunctional devices with composite structures.[5,6,7,8,9] From the time perovskite materials have entered the field of optoelectronic devices, three-dimensional (3D) halide perovskites have climbed to the top performance in just a few years, reaching a power conversion efficiency of 25.2% for photovoltaic devices.[10] the performance of the 3D perovskite is commendable, its shortcomings have become more obvious. According to the current status of the perovskite NCs photodetector, the challenges and development prospects that may be encountered in the future are put forward to provide references for related research and development in the future
