“…These defects are responsible for the reduced diffusion length of carriers, so SRH recombination becomes dominant, which ultimately suppresses the output voltage V OC. [38,39] Mathematically, by observing Equation (15), it has been noted that as temperature rises, the voltage decreases because E g /q is always greater than V OC . Meanwhile, extra thermal energy also encourages the creation of electron-hole pairs, that is, more excitons generation.…”

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.

The paper describes the solar cell's design, ITO/CdS/Sb2Se3/CZTSe/Au. Experimental evidence that supports the model's predictions regarding output performance and current-voltage characteristics comes from CdS/Sb2Se3 solar cells with a hole transport layer (HTL). Sb2Se3 could be used in solar cells because it is non-toxic, affordable, and performs well. Because Sb2Se3 has a high-power conversion efficiency (6.5%), it is utilized as the absorber in thin-film solar cells. By simulating a best-practice solar cell configuration, including device optimization and band offset engineering, the SCAPS-1D simulator increased solar cell efficiency. The J-V characteristics of the simulated systems were simulated using SCAPS-1D to confirm the accuracy of the results. Current research focuses on the absorber for antimony selenide photovoltaic solar cells. The solar capacitance simulator was used to evaluate thin Sb2Se3 solar cells using SCAPS-1D software. From all the simulations, the conclusion arises that CZTSe as HTL gave the highest values of open-circuit voltage (VOC), i.e., 311mV, short circuit current (JSC), i.e., 28.246%, Fill Factor (FF), i.e., 45.48%, and Power Conversion Efficiency (PCE), i.e., 4%, was obtained through proposed solar cell architecture ITO/CdS/Sb2Se3/CZTSe/Au.

“…In that sense, numerical simulation can be a very useful tool for studying solar cell performance. One of these tools is the SCAPS 1D software (version 3.3.09), which has been shown to be useful for investigating various solar cell parameters such as device thickness, resistance, and temperature [ 3 ], the theoretical impact of novel hole transport layers [ 4 ], and multiple terminal tandem perovskite devices [ 5 ], or even estimating the potential solar cell devices comprising chalcogenide-based perovskite active layers [ 6 ].…”

Simulation and Optimization of FAPbI3 Perovskite Solar Cells with a BaTiO3 Layer for Efficiency Enhancement

Since the addition of BaTiO3 in perovskite solar cells (PSCs) provides a more energetically favorable transport route for electrons, resulting in more efficient charge separation and electron extraction, in this work we experimentally prepared such a PSC and used a modeling approach to point out which simulation parameters have an influence on PSC characteristics and how they can be improved. We added a layer of BaTiO3 onto the TiO2 electron transport layer and prepared a PSC, which had an FTO/TiO2/BaTiO3/FAPbI3/spiro-OMeTAD/Au architecture with a power conversion efficiency (PCE) of 11%. Further, we used the simulation program SCAPS-1D to investigate and optimize the device parameters (thickness of the BaTiO3 and absorber layers, doping, and defect concentration) resulting in devices with PCEs reaching up to 15%, and even up to 20% if we assume an ideal structure with no interlayer defects. Our experimental findings and simulations in this paper highlight the promising interplay of multilayer TiO2/BaTiO3 ETLs for potential future applications in PSCs.
