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].Nevertheless,the long-term stability of MHP materials and devices is a critical barrier to commercial applications[4].
