This review provides a comprehensive overview of the effects of mixing on the structural phase transitions, crystal symmetry, cation and lattice dynamics, and phase diagrams of three-dimensional (3D) and low-dimensional lead halide perovskites. The authors highlight the benefits of mixing, such as improved stability, photovoltaic performance, and tunability of optical properties. They discuss the structural phase transitions in non-mixed 3D lead halide perovskites, including MAPbI₃, MAPbBr₃, MAPbCl₃, FAPbI₃, FAPbBr₃, FAPbCl₃, CsPbI₃, CsPbBr₃, CsPbCl₃, MhyPbX₃, and AZRPbX₃. The review also explores the structural phase transitions in lead halide perovskites with two cations, such as Ruddlesden–Popper (RP) and Dion–Jacobson (Dj) phases. The authors analyze different mixing recipes and ingredients, providing insights into the mixing effects and their impact on the attractive properties of these materials. The review concludes with a discussion on the common aspects observed in different mixed systems and an outlook for future research.This review provides a comprehensive overview of the effects of mixing on the structural phase transitions, crystal symmetry, cation and lattice dynamics, and phase diagrams of three-dimensional (3D) and low-dimensional lead halide perovskites.
