Inhibiting Ion Migration and Oxidation in Sn–Pb Perovskite by Multidentate Chelating Additive Strategy

Tianjun Ma,

et al.

Abstract: Currently, all‐perovskite tandem solar cells have achieved power conversion efficiencies exceeding 29%. The further improvement is limited by mixed Sn–Pb narrow‐bandgap perovskite subcells. The facile oxidation of Sn2+ to Sn4+ poses an inherent challenge that limits the efficiency and stability of Sn–Pb perovskite solar cells. In this study, a multi‐dentate chelating additive, 3‐amino‐2‐chloroisonicotinamide (ACPC), is developed. Its amino group could anchor I− of the perovskite lattice by hydrogen bonds, ther… Show more
