摘要

Nowadays,perovskite materials become research hot-spots with the soar of the power conversion efficiency(PCE)for perovskite solar cells.Specifically,metal halide per-ovskites(MHPs),with the formula ABX3(A=CH3NH3+(MA+),CH(NH2)2+(FA+),Cs+,etc.;B=Pb2+or Sn2+;and X=I-,Cl-and/or Br-),have become star materials in optoelectronics.MHPs present favorable optoelectronic properties,like high absorption coefficient in visible range,long carrier diffusion length,high defect tolerance,and superior optical gain in a wide wavelength range.These merits gift MHPs promising po-tential in optoelectronic application,including solar cells,light-emitting diodes,photodetectors and lasers.This article introduces the star perovskite materials in milestone works and highlights the best-performing materials in respective op-toelectronic application.
