Organic solar cells (OSCs) are promising wearable/stretchable power sources, but the development of high-performance intrinsically stretchable OSCs (SOSCs) has rarely been reported. Herein, SOSCs exhibiting high power conversion efficiencies (PCEs) (>12%) and excellent stretchability are developed by constructing efficient and mechanically robust active layers via the addition of a high-molecular weight polymer acceptor (PA) to polymer donor:small-molecule acceptor blends. PA addition significantly enhances the stretchability and PCEs of the blends as the long PA chains function as molecular bridges between different domains, effectively dissipating mechanical stresses and improving charge transport.
