In this paper,we focus on the impact of ion migration on the short-circuit current(Jsc)and open-circuit voltage(Voc)in perovskite thin-film solar cells.Through theoretical modeling and calculations,we have found that ion migration significantly affects the Voc of the cells and is confirmed to be the primary cause of the J-V hysteresis effect.Additionally,we studied various kinetic parameters affecting cell performance,such as diffusion coefficients,carrier lifetimes,and injection rates.We also investigated the relationship between these parameters and the thickness of the perovskite film.This model reveals the factors influencing the photovoltaic performance of the cells,providing critical scientific insights for the performance and device optimization of perovskite solar cells.
