摘要
The rapid advancement of metal halide perovskites can be attributed to their exceptional optoelectronic properties and facile solution processing technique.Noteworthy strides have been achieved in the realm of perovskite solar cells(PSCs),with a certified power conversion efficiency(PCE)escalating to 26.7%over the course of a decade,positioning them as promising contenders for next-generation photovoltaic technologies[1].However,the formation of crystal defects,including anion/cation vacancies,Pb–I antisite defects,and uncoordinated Pb^(2+),along the surface and grain boundaries(GBs)of perovskite layers during the solution processing stage poses a significant challenge,compromising the photoelectric performance and stability of PSCs.
