Abstract Current state‐of‐the‐art organic photovoltaic (OPV) films, composed of conjugated polymer donors and small molecule acceptors, are often limited by the high brittleness their rigid backbones, which restricts application in wearable devices. In contrast, all‐polymer OPVs have demonstrated enhanced intrinsic stretchability, but further advancements necessary to meet demands. Here, an uncharted strategy is reported enhance mechanical stretchability performance incorporating a nearly‐amorphous polymer, poly(indacenodithiophene‐co‐benzothiadiazole) (IDTBT) into layer‐by‐layer structured active layer. IDTBT possesses fracture strain ≈80%, significantly outperforming well‐known donor polymers like PM6. The incorporation enhances properties, with both optimized at low contents. More importantly, intrinsically stretchable demonstrate superior stability impressive power conversion efficiency 14.2%, highest date this category. Particularly, IDTBT‐strengthened retain 72% initial under tensile 50%, 68% even after being stretched hundreds times 30% strain, demonstrating exceptional stability. This approach underscores potential semiconductors designing highly OPVs, paving way for seamless integration electronics.

Abstract Almost all of central cores in high‐performance acceptors are limited to the electron‐withdrawing diimide structure currently, which constrains further acceptor structural innovation greatly. Herein, oxygen (O), sulfur (S), and nitrogen (N) atoms adopted bridge 2D conjugated cores, yielding three platforms CH─O, CH─S, CH─N that differ by only two atoms. Because characteristic atomic outer electron configuration hybrid orbital orientation, O‐, S‐, N‐bridged display quite different conformations electronic properties, namely, dibenzodioxin (planar, non‐aromatic), thianthrene (puckered, non‐aromatic) phenazine aromatic), respectively. A systematic investigation discloses how core, especially its p‐π overlap between lone pair on O/S/N coterminous benzene planes, affect intrinsic photoelectronic properties for first time. Finally, CH─N‐based binary device affords highest fill factor 83.13% organic photovoltaics along with a first‐class efficiency 20.23%. By evaluating strictly controlled molecular comprehensively, work reveals potential uniqueness determining excellent photovoltaic outcomes acceptors.
