Metal halide perovskites of the general formula ABX3—where A is a monovalent cation such as caesium, methylammonium or formamidinium; B is divalent lead, tin or germanium; and X is a halide anion—have shown great potential as light harvesters for thin-film photovoltaics1,2,3,4,5. Among a large number of compositions investigated, the cubic α-phase of formamidiniumleadtriiodide (FAPbI3) has emerged
