Dataset of "Light-induced Surface Recombination Suppression, Carrier Lifetime Improvement, and Deep Defect Formation in Lead Halide Perovskites "

Lead halide perovskites are promising materials in a wide range of optoelectronic devices. The internal instabilities of perovskites under illumination, however, hinder their application. Here, we study the light-induced changes in CH3NH3PbBr3 single crystals, focusing on charge carrier transport properties and deep defect evolution. Using laser-induced transient current technique measurements under steady-state illumination enables us to distinguish electron and hole conductivity.
