As all-polymer solar cells (all-PSCs) have achieved impressive power conversion efficiencies (PCEs), extending their lifetime under long-term operation is also increasingly important. To address this issue, in study, a new pseudo-quaternary blend composed of conjugated block copolymer donors and acceptors, PM6-b-TT:b-PYT, introduced as the active layer for all-PSCs. Compared to all-PSC based on traditional binary blend, PM6:BTTP-T, those exhibited significantly improved thermal stability after annealing harsh conditions 150 °C an ambient atmosphere. More importantly, elucidate morphological layer, visible evidence thin film's surface internal structure carefully investigated by multiple advanced techniques. After extended stress at °C, bulk heterojunction (BHJ) films exhibit excessive polymer chain aggregation, phase separation polymers, increased roughness, forming charge traps increasing exciton recombination. Meanwhile, BHJ maintain crystallinity nanostructure improving Overall, study provides detailed understanding high-efficiency all-PSCs, offering key insights into section proposing promising structures

Abstract Intrinsically stretchable organic photovoltaic cells (OPVs) have garnered significant attention as crucial devices for powering next‐generation wearable electronics. Despite the rapid power conversion efficiency gains in champion OPVs, their brittle stretchability has failed to meet demands of Internet Things era, severely hindering further development and practical applications. In this regard, a new dual‐donor polymer blending strategy is demonstrated constructing intrinsically OPVs by designing novel high‐molecular–weight conjugated PM6‐HD. This PM6 derivative featuring long alkyl chains can reach sufficiently high molecular weight thus exhibits fracture strain exceeding 90%, which ≈12 times higher than benchmark PM6. Synergistic optimization mechanical properties performance polymer:small molecule all‐polymer systems constructed from physical blends PM6‐HD achieved. Crucially, resulting OPV demonstrates excellent stability, with record PCE 80% 50.3% retention above even after 1000 cycles cyclic stretching at strains. work contributes advancement technology opens up possibilities its integration into electronic devices.
