Organic solar cells (OSCs) have witnessed significant advancements in recent years, largely propelled by innovations material design and device engineering. Among the emerging materials, dimerized small-molecule acceptors (DSMAs) garnered considerable attention due to their unique advantages. For instance, DSMAs can directly inherit excellent optoelectronic properties of corresponding monomers. Moreover, relatively larger molecular weight effectively suppress diffusion active layer, thereby enhancing stability OSCs.

This review comprehensively summarizes progress for OSCs, with focus on two primary linkage configurations: conjugative non-conjugative connections. Additionally, impact various connection positions (including core-unit, end-group, side-chain sites) packing, properties, performance systematically reviewed. The highlights critical role addressing key challenges such as photodegradation morphological instability, while balancing power conversion efficiency long-term stability. By consolidating breakthroughs identifying future research directions, this work aims provide valuable insights into rational DSMAs, paving way development high-performance commercially viable

Emerging wearable devices would benefit from integrating ductile photovoltaic light-harvesting power sources. In this work, we report a small-molecule acceptor (SMA), also known as non–fullerene (NFA), designed for stretchable organic solar cell ( s -OSC) blends with large mechanical compliance and performance. Blends of the organosilane-functionalized SMA BTP-Si4 polymer donor PNTB6-Cl achieved conversion efficiency (PCE) >16% ultimate strain (ε u ) >95%. Typical SMAs suppress OSC blend ductility, but addition enhances it. Although is less crystalline than other SMAs, it retains considerable electron mobility highly miscible essential enhancing ε . Thus, -OSCs PCE > 14% operating normally under various deformations (>80% retention an 80% strain) were demonstrated. Analysis several SMA-polymer revealed general molecular structure–miscibility–stretchability relationships designing blends.
