Ion-mixing is a highly effective strategy for tuning the performance and stability of photovoltaic devices based on hybrid perovskites. Despite many works concentrating A- X-site mixing effects, comprehensive study effects B-site structural dynamic properties MA-based perovskites still absent. In this work, we investigate mixed lead–tin halide MAPb1–xSnxBr3 using multitechnique experimental approach including differential scanning calorimetry, dielectric spectroscopy, nuclear quadrupole resonance experiments. We map phase diagram system, which reveals that slightly stabilizes cubic affects MA cation dynamics ordering, although observed are less prominent compared with mixing. Our results provide insights into complex interplay in mixed-metal contributing to their potential optimization applications.

We demonstrated the construction of binary phase diagrams coordination polymer crystals by using their reversible solid–liquid transition (melting and crystallization) behaviors. Three types Ag+-based polymers were made origins each diagram formation investigated. All showed eutectic phenomena induced ligand exchange reactions at interface two constituents. Solid solution was observed when we used with similar structures geometries, reaction driven both anion processes. The optimal compounds found in applicable as a latent heat storage material working 100 °C high energy recovery efficiency, stability phase-transition cycles, large hysteresis melting/crystallization.
