Popis:	We show that the addition of 1 % (v/v) nitrobenzene within the perovskite formulation can be used as a method to improve the power conversion efficiency and reliability performance of methylammonium-free (CsFA) inverted perovskite solar cells. Addition of nitrobenzene increased PCE due to defect passivation and provides smoother films resulting in PVSCs with narrower PCE distribution. Moreover, the nitrobenzene additive methylammonium-free hybrid PVSCs exhibit prolonged lifetime compare to additive free PVSCs due to enhanced air and moisture degradation resistance.
