The improvement in the efficiency of inverted perovskite solar cells(PSCs)is significantly limited by undesirable contact at the NiOx/perovskite interface.In this study,a novel microstructure-control technology is proposed for fabrication of porous NiOx films using Pluronic P123 as the structure-directing agent and acetylacetone(AcAc)as the coordination agent.The synthesized porous NiOx films enhanced the hole extraction efficiency and reduced recombination defects at the NiOx/perovskite interface.Consequently,without any modification,the power conversion efficiency(PCE)of the PSC with MAPbl3 as the absorber layer improved from 16.50％to 19.08％.Moreover,the PCE of the device composed of perovskite Cs0.05(MA0.15FA0.85)0.95Pb(I0.85Br0.15)3 improved from 17.49％to 21.42％.Furthermore,the application of the fabricated porous NiOx on fluorine-doped tin oxide(FTO)substrates enabled the fabrication of large-area PSCs(1.2 cm2)with a PCE of 19.63％.This study provides a novel strategy for improving the contact at the NiOx/perovskite interface for the fabrication of high-performance large-area perovskite solar cells.
