Abstract

For decades, many studies have been conducted to improve the efficiency of photovoltaic devices. In this study, we focused on structural properties, especially phase transition behavior as a results of temperature changes in methylammonium lead halide perovskite (CH3NH3PbX3, XI, Br, and Cl) to understand fundamental properties in these materials. The properties of perovskite materials on halogen elements, and Raman scattering can show that the contribution to the structural phase transition from each atomic/molecular vibration varies from compound to compound.
