Behavioral Model of Perovskite Solar Cells

Abstract

A behavioral model of perovskite solar cells is developed. The model equations are semi-empirical and they are coded in Matlab. The equations describe the current density, voltage and power conversion efficiency at different irradiance despite of the fact that perovskite solar cells have hysteresis characteristics. Simulation data arejuxtaposed with experimental data for a FTO/c-TiO2/mp-TiO2/MAPbI3/ OMeTAD/Au cell. The results very well predict the values for the current density and voltage at high irradiance but at low irradiance the current is underestimated and the voltage is overestimated. The mean difference of the predicted power conversion efficiency remains under 1 % regardless of the scanningreverse or forward.
