Like lead, tin is also one of the group IV elements and the divalent cation of Sn 2+ has an ionic radius of 118 pm, almost the same size as Pb 2+ cation (119 pm). These similarities attribute to tin-based perovskite displaying the closest optoelectrical and crystallographic properties to lead-based perovskite.
Tin-lead halide perovskites have great photovoltaic potential, either as a single-junction solar cell 1, 2, 3 or as a subcell in all-perovskite tandems 4, 5, 6, 7. Compared to lead perovskites, the incorporation of tin can extend the exploitation of the solar spectrum and reduce toxic lead content.
