Impact of Organic/Hole Transport Layer in Efficiency ‎Optimization of SnO₂/CH۳NH₃PbI₃/Org/HTL ‎Perovskite Solar Cell: A Simulation Study

In solar energy applications, CH۳NH۳PbI۳ has offered a breakthrough in perovskite solar cell (PSC) research with different hole transport layers (HTL) and electron transport layers (ETL). This investigation studies CH۳NH۳PbI۳ PSC with SnO۲ as ETL and CuSCN or CuI as HTL. P۳HT and MEHPPV as an organic layer (Org) are inserted between CH۳NH۳PbI۳ and HTL. A simulation study is carried out on four combinations of SnO۲/CH۳NH۳PbI۳/Org/HTL/Au PSCs using SCAPS-۱D. The current-voltage characteristics and energy bandgap of all the PSCs are discussed. The SnO۲/CH۳NH۳PbI۳/P۳HT/CuSCN/Au is the best PSC with Voc of ۱.۱۵۹ V, Jsc of ۲۵.۳۵۹ mA/cm۲, fill factor of ۷۶.۹۹% and a promising higher efficiency of ۲۲.۶۳% than others. The photovoltaic parameters of SnO۲/CH۳NH۳PbI۳/Org/HTL/Au are analyzed by varying the temperature, the thickness of the organic layers, and the bandgap of both the organic and inorganic HTLs to optimize the efficiency. Capacitance-voltage (C-V) plots are generated at various frequencies for all the proposed PSCs. The simulation results present a promising approach for the future design of highly efficient and stable PSCs.
