Solvent-assisted reaction for spontaneous defect passivation in perovskite solar cells - Nature Photonics Solvent engineering by the addition of 1,4-butane sultone in a perovskite precursor solution simultaneously enhances the crystallization of the perovskite and passivates defects, resulting in a power conversion efficiency of 26.5%. https://go.nature.com/3JLHNWE
