Star-branched polymer donors enabling high-performance organic solar cells with superior flexibility and intrinsic stretchability
Emerging wearable electronics rely on organic solar cells (OSCs) for flexibility and stretchability, but balancing efficiency and mechanical robustness is challenging. This research introduces star-branched polymer donors (SPDs) with intramolecular crosslinking, significantly enhancing fracture strain (up to 19.16% vs. 10.46% for linear PM6). These SPDs self-assemble into refined fibrous architectures, preserving optoelectronic properties. S2:L8-BO OSCs achieved 19.51% (rigid), 18.39% (flexible), and 15.40% (stretchable), with ternary versions reaching 20.48%. This molecular engineering strategy overcomes the efficiency-compliance trade-off, paving the way for high-performance wearable electronics.

Breakthrough in Star-branched Polymer Donors (SPDs)
0 Highest Fracture Strain Achieved with S3 SPDThe introduction of 1,3,5-tris(bromomethyl)benzene as a multi-reactive-site unit enables the covalent crosslinking of PM6 polymer chains, forming an intramolecular meshing architecture. This significantly mitigates aggregation and enhances flexibility and stretchability. SPDs S1, S2, and S3 demonstrated fracture strains of 12.70%, 15.33%, and 19.16%, respectively, significantly exceeding the 10.46% of linear PM6.

Towards Wearable Electronics: A Case Study in Robust Energy
The development of these star-branched polymer donors (SPDs) represents a significant leap for wearable electronics. Traditional organic solar cells struggled to balance high efficiency with the mechanical compliance required for flexible and stretchable applications. SPDs, particularly S2, demonstrate the ability to achieve 19.51% PCE in rigid devices, 18.39% in flexible devices, and 15.40% in intrinsically stretchable devices. Furthermore, their superior fatigue endurance and stress resistance, retaining over 80% PCE after 6000 bending cycles and demonstrating remarkable strain stability, positions them as a reliable power source. This addresses a critical market need for durable and high-performing flexible energy solutions, reducing replacement cycles and enhancing user experience in smart textiles, biomedical sensors, and portable devices.
The ability to achieve 20.26% PCE in o-xylene processed ternary devices also facilitates green, large-area fabrication, making commercial scaling more environmentally friendly and cost-effective.
