Perovskite solar cells have garnered substantial attention from the global research community due to their rapidly improving power conversion efficiency and low-cost fabrication potential. In this study, tranexamic acid was introduced as an additive to enhance the photovoltaic performance of CsPbI₂Br-based perovskite solar cells. Photovoltaic characterization demonstrated that the incorporation of 0.5% tranexamic acid led to a pronounced improvement in the current–voltage (J–V) characteristics of the devices. Consequently, both the open-circuit voltage and fill factor were markedly improved, resulting in an increase in power conversion efficiency from 7.63% to 12.14%. These findings confirm that tranexamic acid serves as an effective additive for regulating charge carrier dynamics and improving the overall photovoltaic performance of CsPbI₂Br perovskite solar cells.
