In order to minimize the environmental pollution and realize large-scale production, green chemicals are very necessary. In this work, we report the impact of ethyl acetate (EA) antisolvent treatment on the performance of fully air-fabricated planar perovskite solar cells (PSCs). The proposed spin-coating approach with the antisolvent treatment was compared with the sequential spin-coating deposition process. Our findings demonstrated that the antisolvent treatment with green EA enhances the optoelectronic features and morphology of the fabricated methylammonium lead iodide (MAPbI

) film. Also, the charge transfer is enhanced, and hence, the interfacial recombination is significantly suppressed, resulting in boosted power conversion efficiency of 17.75% for the best PSC with enhanced thermal and ambient stability.
