Device simulation of CH3NH3PbI3 perovskite solar cell with high efficiency

With the combination of both electrical approach and optical approach, this paper investigates the n-i-p perovskite solar cell with the most optimized design structure. The proposed approach is mainly based SCAPS-1D Simulator. Here the experimental results of CH3NH3PbI3 perovskite solar cell device are compared to SCAPS-1D simulation results and obtained high power conversion efficiency by optimizing the device parameters. In this paper the change in the parameters of the device like defect density,interface defects,carriers cross sections and doping concentration of Absorber Layer, Electron Transport Layer(ETL) and Hole transport Layer(HTL) are observed with their effect on the performance of the device. The efficiency of preliminary structure of the solar cell device is 19.08% in case of experimental work and 15.8% in case of SCAPS simulation. Then after optimizing the device parameters, the final performance parameters are enhanced to 1.79 V of open circuit voltage(Voc), 40.35% Fill Factor, 22.33% Optimized Power Conversion efficiency and short circuit current(Jsc) of 30.83mA/cm2.
