This invention belongs to the field of solar cell technology, specifically a method for preparing a wide-bandgap perovskite thin film with a uniform initial phase and an inverted perovskite solar cell. The method involves mixing a K-ion-containing additive solution with a wide-bandgap perovskite solar cell precursor solution, spin-coating the mixture onto a substrate, and annealing to obtain the wide-bandgap perovskite thin film. This invention optimizes the initial phase separation phenomenon caused by different halide ion nucleation rates during the crystallization process of the wide-bandgap perovskite thin film by introducing K-ions as an additive into the perovskite precursor solution. This strategy not only promotes uniform crystal growth in the perovskite thin film but also effectively suppresses problems such as high defect density caused by initial phase inhomogeneity and halide ion migration under illumination, reducing voltage loss of the inverted perovskite solar cell under open-circuit conditions, thereby achieving higher photoelectric conversion efficiency and better long-term stability.
