Our study shows that the introduced EWMs can improve perovskite device performance by enhancing chemical passivation and interface dipole effect, as well as chemical binding to Spiro-OMeTAD. After optimization, devices modified with F4TCNQ achieved a remarkable 25.21 % efficiency and displayed long-term stability. Additionally, large-scale devices (14.0 cm²) using this approach achieved a high 21.4 % efficiency.
