“…In the past few decades, scientists have seen great progress in lead halide perovskites with their application in LEDs, [1][2][3] photovoltaic devices, [4][5][6] lasers, [7][8][9] photocatalytic degradation, 10 photodetection, 11 and so on, in particular with photovoltaic power generation. Taking perovskite solar cells (PSCs) as an example, after the pioneering PSC report of Miyasaka and colleagues in 2009, 12 the reported photovoltaic conversion efficiency (PEC) in PSCs can reach more than 25.2%.…”
