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.

“…For potential usage as active absorber materials in multilayer PSC, other perovskites and non-perovskites materials are also researched and numerically modeled. Moreover, research has shown that pure organic perovskite materials are appropriate for absorber layers in PSCs [10]. The cation A is organic (Methyl-ammoniumCH3NH3]+), M is Pb, and X might be I (iodine), Br (bromine), or Cl (Chlorine), according to the study of CH3NH3PbX3 organic lead halide perovskites.…”

This paper presents theoretical research work for device simulation of solar cells based on Methylammonium lead iodide CH3NH3Pb(I1 − XBrx)3 concentration, band offsets, and other characteristics that have an impact on efficiency. SCAPs software is utilized to model and simulate the proposed solar cell. The results obtained of the proposed solar cell design have high efficiency of 36.44%. Copper iodide (CuI) as the hole transport material and Tin oxide (SnO2F) as the transparent conducting oxide are implemented in design to analyze the characteristics of perovskite solar cells (PSC). The results demonstrate that the proposed design have identical concepts but enhanced outcome compared to the existing one. The quantum efficiency curve depicts that the perovskite material has good absorption across the full visible spectrum. CH3NH3Pb(I1 − XBrx)3 solar cells are emerging as an important renewable energy source for current and future context. Research is being carried for enhancement in solar cell designs.

“…An absorber layer of a PSC incorporates perovskite structure having general formula CDX3 where C denotes organic cation viz formamidinium (NH=CHNH3 + ) or methyl ammonium (CH3NH3 + ), D denotes inorganic cation viz Sn 2+ and Pb 2+ and X denotes halide ion viz Cl -, Bror I -. Methyl ammonium lead iodide (MAPbI3) is the most common perovskites used in PSCs while MAPbI3-xClx, MAPb(I1-xBrx)3, MAPbSnI3, MAPbI3, FASnI3 are the other perovskite materials used as absorber layers for constitution of perovskite solar cell [1][2][3][4][5]. Various perovskites & non perovskites material are also examined & numerically simulates for further utilization as active absorber material in multilayer PSC.…”

Mathematical modelling can offer the physical intuitions about the charge transport process inside a solar cells and provide the various elements affecting their performance. In the present paper, (CH3NH3Pb(I1-xBrx)3 based various perovskite solar cells have been mathematically simulated deploying SCAPS simulator. Various Hole Transport layers (HTLs) based on thickness, total defect density and donor density of mixed halide perovskite have been compared using Cd1-xZnxS as an Electron Transport Layer (ETL). Amongst the proffered HTLs, P3HT [Poly(3-hexylthiophene)] executed better and exhibited the PCE of 28.28%. During the simulation, mixed halide perovskite layer with thickness of 700 nm has been found suitable for the effective solar cell design. These mathematically simulated outcomes indicate the optimum efficiency of the solar cell that may further be prompted to design the extremely high efficient solar cells.
