Tailoring the Crystallization Behavior of Mixed Lead‐Tin Mixed‐Halide Perovskites for Optimal‐Bandgap Solar Cells

Abstract Incorporating bromide into metal‐iodide perovskites is a commonly used approach for widening the bandgap of lead‐halide perovskites. Here, mixing of iodide and bromide is explored in narrow‐bandgap lead‐tin perovskites to create a Cs0.1FA0.6MA0.3Pb0.5Sn0.5I2.5Br0.5 perovskite composition, a...
