Abstract The interfacial management in perovskite solar cells (PSCs), including mitigating the carrier transport barrier and suppressing non‐radiative recombination, still remains a significant challenge for efficiency stability enhancement. Herein, by screening family of fluorine (F) terminated dual‐site organic dipole molecules, study aims to gain insight into molecular array toward tunable field. Both experimental theoretical results reveal that these functional molecules can effectively anchor on surface through Lewis acid‐base interaction. In addition, tailored side‐chain with F atoms allows altering constructing well matched perovskite/Spiro‐OMeTAD contact. As result, inserting modulates interface deliver gradient energy level alignment, facilitating extraction transport. optimal trifluoro‐methanesulfonamide mediated N‐i‐P PSCs achieve highest 25.47%, together enhanced operational under 1000 h simulated 1‐sun illumination exposure. These findings are believed provide design sufficient tunability perovskite‐based optoelectronic devices.
