Abstract Organic solar cells (OSCs) typically exhibit large energy disorders due to the complicated blend morphology, which is one of important factors in limiting improvement power conversion efficiencies (PCEs). Herein, two new cross‐shaped donor molecules, BTCl‐4R and BT‐4R, featured with central benzodithiophene (BDT) cores flanked four π‐bridges hexylrhodanine end groups are developed, introduced into OSCs as a third component optimize packing behaviors reduce disorder. By blending classical PM6:L8‐BO system, outstanding PCE 20.03% low disorder 32 meV achieved, higher order lowers trap density inter‐connected morphology facilitates establishment more charge transport channels. This study demonstrates significant potential multi‐arm molecules constructing high‐performance OSCs.

Abstract Regulating blend morphology in photoactive films is essential for enhancing the power conversion efficiency (PCE) of organic solar cells (OSCs). However, achieving precise control over remains a significant challenge due to difficulty simultaneously controlling thermodynamic and kinetic parameters that govern formation. In this study, series new small‐molecule acceptors (SMAs) employing dual side chain functionalization strategy designed incorporates trifluoromethyl (CF 3 ) phenyl (Ph) groups: SMA‐CH , SMA‐CF (with CF group), SMA‐Ph‐CF both groups). This approach successfully enables delicate tuning development high‐performance OSCs (PCE = 18.5%). enhances compatibility SMAs with hydrophobic D18 polymer donor, promoting formation intermixed donor/acceptor domains efficient charge generation. Meanwhile, improves SMA aggregation crystallinity, facilitating strong interconnected assembly transport. As result, binary based on D18:SMA‐Ph‐CF achieve significantly higher PCE 18.5%, compared 14.3% D18:SMA‐CH 16.5% D18:SMA‐CF OSCs. These results highlight importance optimizing

Abstract Polymer solar cells (PSCs) rely on blends of small‐molecule acceptors (SMAs) and polymer donors, but the thermodynamic relaxation SMAs requires an oligomeric approach to enhance operational stability. However, high‐efficiency devices often depend expensive synthesis costly posing a significant barrier achieving sustainable renewable energy. Here, challenge is addressed through thermodynamically derived compatibility giant with low‐cost donor PTQ10. This achieved by strategically employing conjugated side chains modulate dimerize acceptors, thereby precisely tuning their properties optimize compatibility. Our synthetic route avoids toxic reagents, halogenated solvents, harsh conditions. The dimer (DYBT) incorporating n ‐type linker enhances crystallinity, absorption, intramolecular superexchange coupling compared its p counterpart, achieves device efficiency 19.53%. Considering efficiency, stability, material cost, potential cost per kilowatt for PTQ10:DYBT 0.10 $ kW −1 , while most systems exceed 10 . These findings offer valuable insights cost‐effective well pair donors reduce overall photo‐active layer durable
