Summary: Terpolymerization and regioisomerization strategies are utilized to develop novel polymer donors for improving the performance of organic solar cells (OSCs). The study shows that the position of chlorine substituents significantly affects the molecular planarity and electrostatic potential (ESP), thereby influencing the aggregation behavior and miscibility of the donor and acceptor. The terpolymer PM6-TTO-10 exhibits enhanced coplanarity, crystallinity, aggregation behavior, and phase separation, leading to efficient exciton dissociation and charge transfer. Consequently, OSCs based on PM6-TTO-10 achieve a high power conversion efficiency of 18.37% with an outstanding fill factor of 79.97%, which are among the highest reported for terpolymer-based OSCs.

Summary: A series of new wide bandgap (WBG) polymers were developed by introducing S, F, and Cl atoms to the alkylthienyl sidechains on BDT, resulting in lowered energy levels and enhanced aggregation properties. Among them, PBTz-F exhibited a low-lying HOMO level and stronger face-on packing order, leading to a high-power conversion efficiency (PCE) of 18.57% in the PF-BTz:L8-BO blend. It also showed good batch-to-batch reproducibility and general applicability. Furthermore, ternary blend OSCs based on the PBTz-F:L8-BO blend achieved a further enhanced PCE of 19.54%, one of the highest values in OSCs.

Summary: Controlling the phase separation of bulk-heterojunction donor/acceptor active layer is a challenge in fabricating high-performance polymer solar cells (PSCs) using strongly crystalline materials. In this study, a molecular design strategy is developed to synthesize three guest materials (BTPT, BTP-Th, and BTP-2Th) as the third component to address this issue. The effect of crystallinity and miscibility of the third component in controlling the phase separation is investigated and a remarkable power-conversion efficiency of 18.53% is achieved in the ternary PSC based on PTQ10:m-BTP-PhC6 with BTP-Th as the third component.

Summary: In this study, it is demonstrated that the dimerization of a small-molecule acceptor (SMA) significantly enhances the stability of SMA-based organic solar cells (OSC). The dimerized SMA (DYBO) leads to high-efficiency OSCs (> 18% PCE), outperforming OSCs based on their monomer counterpart MYBO (PCE = 17.1%). DYBO-based OSCs show excellent thermal and photo stability, retaining over 80% of initial PCE after 6,000 hours of thermal exposure at 100 degrees C, while MYBO-based OSCs degrade to -80% of their initial PCE value in 36 hours. The high stability of DYBO-based OSCs is mainly attributed to its high glass transition temperature (Tg) of 179 degrees C (Tg of MYBO = 80 degrees C) and improved blend miscibility that stabilizes the blend morphology under thermal stress.

Summary: In this study, full-end-capping engineering was utilized as a simple and versatile strategy to enhance the efficiency and stability of non-fullerene organic solar cells (OSCs). The end-capping groups effectively eliminated terminal defects in the polymer chains and optimized various factors such as molecular orientation and film formation process, resulting in improved charge dynamics and reduced energy loss. The devices with full-end-capped polymer donors showed significantly higher efficiencies and long-term stability compared to those without end-capping. Notably, the device based on PM6-T:BTP-eC9 achieved an impressive efficiency of 18.45%, demonstrating one of the highest performances among BTP-eC9 based devices.

Researchers have developed an asymmetric non-fullerene acceptor called AC9, demonstrating a high-performance OPV with a champion efficiency of 18.43%. Comprehensive analysis shows that the improved device performance of AC9-based OPVs is due to a better compromise between charge generation and non-radiative charge recombination compared to symmetric acceptors.
