This study investigates the drift-diffusion behavior in tin-based perovskite solar cells, specifically focusing on CH_3NH_3SnI_3, with the aim of understanding how ion mobility, hysteresis, recombination mechanisms, and material parameters influence device performance. Tin-based perovskites represent a promising alternative to lead-based compounds due to their reduced toxicity and comparable optoelectronic properties, yet they pose challenges related to stability and efficiency. A numerical model was developed by solving the coupled Poisson and continuity equations, incorporating both electronic and ionic transport phenomena. The simulation framework allows for variation in ion mobility, defect density, recombination rates, and built-in potential, enabling a comprehensive analysis of dynamic and steady-state responses. The results reveal a significant dependence of hysteresis behavior on ion migration and recombination at interfaces, as well as a notable impact of ionic mobility on current-voltage characteristics and power conversion efficiency. Furthermore, the model shows that optimization of material parameters can mitigate hysteresis and enhance device stability and output. These findings provide valuable insights into the physical mechanisms limiting the performance of tin-based perovskite solar cells and suggest strategies for their improvement through targeted material and device engineering. © The Author(s) 2025.

Практическое значение
The practical significance of this study lies in advancing the development of high-performance and environmentally friendly tin-based perovskite solar cells as a viable alternative to lead-based photovoltaic technologies. By providing a detailed numerical analysis of drift-diffusion processes, ion migration, recombination mechanisms, and hysteresis effects in CH₃NH₃SnI₃ solar cells, the research identifies the key factors limiting device efficiency and stability. The developed model enables researchers and engineers to predict the influence of material properties and operating conditions on solar cell performance without extensive experimental costs. The findings demonstrate that optimizing ion mobility, defect density, and interface recombination can significantly reduce hysteresis, improve power conversion efficiency, and enhance long-term operational stability. These results offer practical guidelines for material design, device optimization, and manufacturing processes, contributing to the commercialization of non-toxic, cost-effective, and efficient next-generation photovoltaic technologies for sustainable energy applications.Квартиль
