Localized Exciton Dynamics of Perovskite Material using Monte Carlo Simulation: A Temperature Dependent Study

Perovskite material has found a numerous attention in the last few years due to its remarkable application’s in high efficiency photovoltaics $(\sim 21.2$%), light emitting diodes and other optoelectronic devices. However, the optical properties of this material greatly depend on the temperature. A clear understanding of temperature dependence exciton dynamics is thus crucial to implement this material in practical applications. Here, we introduce an exhaustive study on the temperature dependence of photoluminescence properties of methyl-ammonium lead iodide (CH

We also analyze the phonon-assisted dynamics of localized excitons and their effects on the photoluminescence (PL) spectrum of this material. Our result shows a blue shift behavior of PL peak energy with temperature that is well agreed with experimental results. We also elucidate the Full Width at Half Maximum (FWHM) of CH
