For the fabrication of perovskite film via the one-step deposition method, anti-solvent becomes the critical factor to decide the quality of the film. In this work, the influence of four different anti-solvents, which were toluene, chlorobenzene, diethyl ether and ethyl acetate, on crystallinity, morphology and coverage of perovskite film and subsequently photoelectric property of perovskite solar cells were reported. Under fully open air conditions with the relative humidity(RH) as high as 70%, the best de...
