Parametric optimization for the performance analysis of novel hybrid organo-perovskite solar cell via SCAPS-1D simulation

Abstract The perovskite and organic solar cells are becoming the most cognizant of the photovoltaic communities. The Spiro-OMeTAD organic hole transport layer (HTL) shows a significant impact on the CH3NH3SnI3 perovskite solar cell (PSC) with TiO2 as the electron transport layer (ETL). So, we optimized the physical and electrical parameters of the organic HTL. Electrical optimization shows that the power conversion efficiency (PCE) of the cell can reach up to 18.10% for the electron affinity of the organic HTL material of about 2.5eV. Further, the interpretation of the practical scale of series and shunt resistance reveals the maximum PCE of the cell as 13.30% at 0.5Ωcm2 and 1×106Ωcm2 respectively. Also, the performance of the cell is analyzed for the hole mobility of the organic HTL material, which revealed the best PCE of the cell to 13.31%. Moreover, the physical parameters are also optimized for the cell performance with illumination intensities which pointed out that the performance of the novel organic HTL perovskite solar cell is optimum for illumination intensity around 0.5Sun (500Wm-2). Finally, the overall light harnessing efficiency or PCE of the proposed solar cell is declared to be 13.30%, and the other performance parameters as open circuit voltage (Voc), short circuit current (Jsc), and fill factor (FF) are 0.764V, 25.86mAcm−2 and 67.29%, respectively.
