“…[ 29,30 ] To obtain optimal cell performance, R sh and R s should be infinite and zero, respectively. The total current produced in the solar cells and its dependence on resistances can be expressed by the following mathematical expression [ 31 ]

“…This reduction in FF is related to soldering breakdown (contact losses), whereas optical transmission losses bring a drop‐in J SC. [ 31 ] The percentage drop in J SC and PCE is lower for bilayer cases compared to those without bilayer. This is attributed due to the suppression of internal resistance after implementing bilayers.…”

The interfacial defects or imperfections in the multilayer perovskite solar cells (PSCs) are detrimental for efficient and stable devices. To produce highly efficient and stable PSCs, a bilayer between the interfaces of electron‐transport material/perovskite and perovskite/hole‐transport material can be useful for suppressing recombinations at these interfaces. To passivate the interfacial defects at the perovskite/SnO2 and perovskite/Spiro‐OMeTAD for three absorber materials (CsPbI3, FAPbI3, and Cs0.05(FA0.83MA0.17)0.95Pb(I0.83Br0.17)3), a thin layer of WO3 and poly‐bathocuproine interfacial layer is explored using solar cell capacitance simulation in 1D. The optimized device photovoltaic performances significantly improve using bilayers. The power conversion efficiency for the FAPbI3‐based PSCs in bilayer configuration is more than 12% as compared to pristine, whereas open‐circuit voltage is improved by over 13%. The enhancement in device performance is attributed to the reduction of interfacial defects at both the electron transport layer/perovskite and perovskite/hole transport layer interfaces. The proposed interface modification strategy provides a novel approach for fabricating efficient perovskite devices.

C Perovskite–perovskite tandem solar cells (P‐TSCs) are an attractive option to overcome the limitation of Si‐based solar cells due to their ability to deposit in both the top and bottom cells by a simple solution process. Despite these advantages, the power conversion efficiency (PCE) of P‐TSCs still falls behind that of Si‐perovskite tandem devices and is highly limited by the nonradiative recombination between the perovskite and electron transport layer (ETL) interface. In this work, with the help of numerical simulations (SCAPS 1D), the influence of the various ETLs on the performance of P‐TSCs is studied. Different ETLs such as C60, PCBM, ZnO, WO3, CdSe, and In2O3, BCP are incoroprated, which directly interface with the perovskite absorber layer in top (high bandgap absorber layer) and bottom subcell (low bandgap absorber layer) of P‐TSC. The simulation analysis shows that reducing the interface surface defect density and band offsets at the ETL/perovskite interface significantly helps achieving high‐efficiency P‐TSC over 35% . Various remediation for incorporating present simulation analysis into practical devices for better‐performing P‐TSCs is also provided. The analysis provides a pathway toward understanding the reasons behind the current trend of low PCE in 2 terminal P‐TSC and achieving high‐efficiency P‐TSC solar cells.
