Cation engineering provides a route to control the structure and properties of hybrid halide perovskites, which has resulted in the highest performance solar cells based on mixtures of Cs, methylammonium, and formamidinium. Here, we present a multi-technique experimental and theoretical study of structural phase transitions, structural phases and dipolar dynamics in the mixed methylammonium/dimethylammonium MA<sub>1-x</sub>DMA<sub>x</sub>PbBr<sub>3</sub> hybrid perovskites (0 ≤ x ≤ 1). Our resul ...[more]
