摘要

Recently, metal halide perovskite (MHP) materials have achieved a huge breakthrough in photovoltaic and optoelectronic devices due to their high power conversion efficiency, high photoluminescence (PL) quantum yield, and simple, cost-effective preparation.Within a short period, perovskite-based solar cells achieve power conversion efficiency exceeding 25％ [1,2], while perovskite-LEDs obtain external quantum efficiency over 21％ [3].
