Hybrid perovskite solar cells (PSCs) have emerged as a promising alternative to crystalline silicon solar cells, owing to their excellent photovoltaic characteristics and straightforward fabrication processes. However, the rapid crystallization dynamics frequently results in unfavorable film morphology, giving rise to a plethora of defect sites and fostering the formation of trapped non-radiative recombination centers, thus limiting the further advancement and refinement of PSC technology. In this study, we introduce N-benzoylthiourea (N-BzTu) molecules as a passivate agent within PSCs through anti-solvent additive approach. The incorporation of CO and CS functional groups in N-BzTu effectively passivates the under-coordinated Pb
