Thermally induced stress accumulation is a major origin of lattice disorder, defect evolution, and ion migration in perovskite solar cells (PSCs), limiting their long-term operational stability. We develop a dynamic molecular scaffold strategy based on the adduct of α-lipoic acid and N-hydroxysuccinimide ester to mitigate thermomechanical degradation through simultaneous thermomechanical stress buffering, lattice anchoring, and adaptive defect healing. During film formation, DL-α-lipoic...
