Photoluminescence spectroscopy of lead halide perovskite semiconductors and solar cells

摘要

Lead halide perovskites APbX3 [A = Cs~+, CH3NH_3~+ (MA~+), CH(NH2)_2~+ (FA~+);; X = I~-, Br~-, Cl~-] recently attract growing attention because of the high conversion efficiency of perovskite solar cells and potential application to innovative optoelectronic devices.
