Optimization of power conversion efficiency of CH3NH3PbI3 perovskite solar cell with TiO2 as electron transport layer

Because of its interesting optoelectronic properties, Methylammonium Lead Iodide CH3NH3PbI3 perovskite semiconductor is used as an active layer in the development of several emerged solar cells. In this work, the solar cell with the architecture FTO/TiO2/ CH3NH3PbI3/Spiro-MeOTAD/Au is simulated using the sophisticated OghmaNano software. We have studied the influence of some parameters like thickness for different layers, charge carrier mobility of holes and electrons, charge recombination rate, band gap energy and doping in the active layer. The effect of device temperature is also studied. The photovoltaic characteristic curves such as Current density-Voltage (J-V), is represented in this work. The final optimized parameters
