Improved photovoltaic performance of MAPbI3 based solar cells via SCAPs

In the recent years, perovskite solar cells (PvskSCs) have emerged as the promising solar cell technology due to its cost-effectiveness and high photovoltaic performance. Although, various experimental reports demonstrated excellent performance but more development and studies are required before their large scale applications. Thus, it would be of great importance to employ the theoretical investigations which may benefit the researchers to develop the high performance PvskSCs. Recently, simulation studies via solar cell capacitance tool (SCAPs) has received extensive interest of the researchers. It is believed that SCAPs based findings may be useful for experimental studies. Herein, we reported the simulation of MAPbI₃ absorber material based PvskSCs using SCAPs as simulation tool. Titanium carbide (Ti₃C₂) MXene was utilized as additive to improve the performance of the PvskSCs. The effect of thickness of the absorber layer was optimized. Additionally, thickness of titanium dioxide (TiO₂) and 2,2′,7,7′-tetrakis (N,N-di-p-methoxyphenylamine)-9,9′-spirobifluorene (spiro-MeOTAD were also optimized. In addition, three electron transport layers (ETL) were also applied for further studies. The effect of temperature of was also investigated and optimized device exhibited efficiency of 23.32%.
