<正>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
