In the present study, the impact of antisolvents—ethyl acetate, chlorobenzene, and diethyl ether—on the quality of the perovskite layer and the performance of the resulting solar cells was investigated. The perovskite layers, crystallized using these antisolvents, were evaluated through structural, morphological, and optical characterization techniques. The results demonstrate that the choice of antisolvent plays a crucial role in improving the properties of the absorber layer. Among the investigated samples, ethyl acetate led to the formation of a layer with higher crystallinity, improved morphological uniformity, and enhanced light absorption capability. Photovoltaic performance results indicated that the device optimized with ethyl acetate achieved a power conversion efficiency of 12.67%, representing an improvement of approximately 13% and 156% compared to those prepared with chlorobenzene (11.16%) and diethyl ether (4.93%), respectively. Furthermore, the maximum external quantum efficiency for the ethyl acetate-optimized cell reached approximately 80%, indicating the superior effectiveness of this antisolvent in reducing structural defects and facilitating charge transfer.
