摘要
Metal halide perovskite solar cells(PSCs)have attracted extensive research interest in recent years due to their lowcost processing,high power conversion efficiency(PCE),and tunable bandgap enabling tandem photovoltaics(PVs).Over the past decade,PSCs have witnessed an impressive increase in PCEs from 3.8%to 25.5%,which is the highest among thin-film PV technologies and is comparable to those of crystalline silicon solar cells[1].
