Abstract Polymerized small molecule acceptors have recently greatly facilitated the development of all‐polymer solar cells (All‐PSCs) with respect to power conversion efficiencies (PCEs). However, high‐performance and low‐cost polymer donors for All‐PSCs are still lacking, limiting further large‐scale manufacturing All‐PSCs. Herein, this work designs synthesizes a new thiophene derivative, FETVT, featuring vinyl‐bridged fluorine ester‐substituted monothiophene. Incorporation FETVT into yields polythiophene derivative PFETVT‐T, which exhibits deep‐lying HOMO level, suitable solution pre‐aggregation ability, finely‐tuned crystallinity, appropriate thermodynamic miscibility acceptor L15. As result, binary based on PFETVT‐T achieves record PCE 11.81% agood stability, representing breakthrough polythiophenes their derivatives‐based All‐PSCs, is also significantly higher than that (1.92%) its isomerized analog. Remarkably, an impressive exceeding 16% via implementation ternary blend design. These findings offer hopeful pathway toward attaining high‐performance, stable, cost‐effective PSCs.

Abstract High power conversion efficiency (PCE) and mechanical robustness are prerequisites for wearable applications of organic solar cells (OSCs). However, stretchability present active systems (i.e., crack‐onset strain (COS) < 30%) should be improved. While introducing elastomers into is considered a simple method improving stretchability, the inclusion typically results in decrease PCE OSC with limited enhancement due to lack interconnected electrical pathways. In this study, it developed efficient intrinsically stretchable (IS)‐OSCs exceptional robustness, by constructing co‐continuous networks conjugated polymers (D18) (SEBS) within layers. It demonstrated that blend film specific ratio (40:60 w/w) D18:SEBS crucial forming structures, establishing well‐connected channels. Consequently, D18 0.4 :SEBS 0.6 /L8‐BO OSCs achieve 16‐times higher (COS = 126%) than based on D18/L8‐BO 8%), while achieving 4‐times (12.13%) compared SEBS‐rich layers (D18 0.2 0.8 /L8‐BO, 3.15%). Furthermore, ‐based IS‐OSCs preserve 86 90% original PCEs at 50% after 200 stretching/releasing cycles 15% strain, respectively, demonstrating highest among reported IS‐OSCs.
