A green co-antisolvent of propyl acetate is induced to adjust the degree of supersaturation in diethyl ether, enabling pinhole-free, smooth, and uniform perovskite thin films. A high power conversion efficiency up to 20.61% was achieved in a p–i–n inverted MAPbI3 PSC with an impressive fill factor (FF) over 84%.
