Simulation and evaluation of perovskite solar cells utilizing various electron transport layers

Solar cells that contain perovskite have been a significant object for consideration within the field of solar energy, consistently enhancing their efficiency year by year. In our study, we devised a novel architectural configuration for a tin-based perovskite solar cell, incorporating FTO/ZnO/CH$_3$NH$_3$SnI$_3$/Spiro-OMeTAD/Au. Our investigation into the working of this solar cell involved the utilization of the SCAPS-1D, a versatile tool tailored for the analysis of solar cell behavior. Through this simulation software, we explored different electrontransporting layer (ETL) materials and made adjustments to multiple parameters, including ETL and absorber layer thickness. The outcomes of our research produced promising results, showcasing significant enhancements in different solar cell parameters. These favorable findings underscore the growing allure and potential of perovskite solar cells within the realm of renewable energy. The reported CH$_3$NH$_3$SnI$_3$-based PSCs provide a viable path to the implementation of environmentally benign, low-cost, and high-efficiency PSCs.
