DT‐TEMPO, on one side, enhances mobility conductivity by p‐doping Spiro‐OMeTAD, while boosting charge transfer process from with an optimized energy level alignment other side. Additionally, DT‐TEMPO endows capability through introduction of dynamic breaking reconstructing disulfide bond. The achieve impressive power conversion efficiencies, 25.69% rigid substrates (certified 25.30%), 21.23% mini‐modules, 24.19% substrates. Remarkably, FPSCs retain over 90% their initial efficiency even after 20 000 bending cycles ( r = 6 mm) recover ≈95% value process.
