Herein, we demonstrate a rationally designed molecular engineering approach for constructing robust buried bottom interfaces via multifunctional SAMs featuring bidentate phosphonic acid anchors, electron\u2010donating methoxy groups. Such elaborate molecular design enables strengthened interfacial binding, optimized energy\u2010level alignment, suppressed self\u2010aggregation, and oriented perovskite crystallization with relieved residual tensile strain. As a result, rigid PSCs achieve a champion efficiency of 27.15% (certified 26.51%), and flexible PSCs exhibit a remarkable efficiency of 25.37% with outstanding mechanical robustness. Moreover, the optimized devices deliver exceptional operational stability, retaining 97.5% of initial performance after 1000 h of continuous operation under ISOS\u2010L\u20102 protocols. This work provides a universal molecular engineering paradigm toward high\u2010performance and ultra\u2010stable flexible perovskite photovoltaics via robust buried interface
