Herein, a functional molecular bridge is deliberately designed by integrating 3,4-thiophene dicarboxylic acid (TDDA) between the CsPbI<sub>3-x</sub>Br<sub>x</sub> perovskite and TiO<sub>2</sub> layer. It is demonstrated that the TDDA molecule exhibits a higher affinity towards the TiO<sub>2</sub> surface, forming tetradentate chelation through two C=O···Ti bonds and two C-O-H···O bonds. Subsequently, it establishes a connection with perovskite via thiophene S-Pb interaction, thus creating an oriented molecular bridge at the buried interface. This effectively enhances charge extraction, passivates bilateral interfacial defects, alleviates lattice strain, and improves perovskite crystallization. Consequently, the combination of these advantageous characteristics results in a power conversion efficiency (PCE) of 22.04% for a target CsPbI<sub>3-x</sub>Br<sub>x</sub> device with an active area of 0.09 cm<sup>2</sup>. Importantly, when scaled up to larger-area devices with an active area of 1.0 cm<sup>2</sup>, an remarkable PCE of 18.29% was achieved.
