摘要

The poor interface quality between nickel oxide (NiO_x) and halide perovskiteslimits the performance and stability of NiO_x-based perovskite solar cells(PSCs). Here a reactive surface modification approach based on the in situdecomposition of urea on the NiO_x surface is reported. The pyrolysis of ureacan reduce the high-valence state of nickel and replace the adsorbed hydroxylgroup with isocyanate. Combining theoretical and experimental analyses, thetreated NiO_x films present suppressed surface states and improved transportenergy level alignment with the halide perovskite absorber. With thisstrategy, NiO_x-based PSCs achieve a champion power conversion efficiency(PCE) of 23.61% and a fill factor of over 86%. The device’s efficiency remainsabove 90% after 2000 h of thermal aging at 85 ℃. Furthermore, perovskitesolar modules achieve PCE values of 18.97% and 17.18% for areas of 16 and196 cm~2, respectively.
