Özet:

 This study investigates the effect of adding 2,2-dichloroacetamide DCA to the anti-solvent process in perovskite film fabrication. The results show that DCA additive increases the apparent grain size of the perovskite, reduces crystal defects, and improves the optoelectronic properties of perovskite solar cells PSCs. Triple-cation perovskite thin films modified with DCA exhibit a 16 improvement in device performance compared to the unmodified control cell, due to increased emission intensity, longer charge carrier lifetimes, and passivation of surface defects, resulting in reduced hysteresis. The use of DCA reduces charge carrier recombination losses in PSCs, leading to enhancements in fill factor FF, short-circuit current density JSC, and power conversion efficiency PCE, increasing the PCE of the control cell from 12.6 to 14.6. This research highlights the potential of molecular additives to optimize crystallization kinetics, facilitating the development of more efficient PSCs. The findings reveal that DCA additive plays a significant role in enhancing perovskite film quality. This strategy has the potential to improve the structural integrity and optoelectronic properties of perovskite layers, thereby enhancing the performance of solar cells.
