Abstract
/Spiro-OMeTAD/Au perovskite solar cell by considering resistance paths, reflection in front contact (FTO), and recombination (radiative and Auger) through SCAPS-1D software. For this, the effect of each of these nonidealities was investigated step by step. The efficiency results of the studied solar cell represented significant differences between the efficiency of the device before and after the application of these conditions that was from 19.26% to 8.40%. This significant decrement is mainly due to the reflection and radiative recombination. Besides, to optimize each of the active layers' essential properties, the effect of mentioned parameters, including thickness and doping density, was investigated in terms of efficiency and recombination plots. The novelty of this research was in employing the non-ideal conditions in the simulation phase and approximating them to the reported experimental works' outcomes. Moreover, utilizing the recombination plots helped a lot in choosing the optimum layer property, e.g., doping density selection. Finally, after optimizing all the properties mentioned above, the efficiency was enhanced by about 4% and reached PCE = 12.83%. The general results represent that despite the significant reduction in the cell performance, the simulated cell is closer to the experimental conditions and offers a better model of a solar cell.
