An A-D-A′-D-A type unfused nonfullerene acceptor for organic solar cells with approaching 14% efficiency

Xingzheng Liu et al.

Summary: In recent years, significant improvements have been made in the power conversion efficiency (PCE) of organic solar cells (OSCs) by exploring new active layer materials, especially high efficiency acceptors. Unfused-ring acceptors (UFAs) have attracted attention for their advantages of simple synthesis and low cost compared to fused-ring acceptors. The synthesis of a new UFA BTzO-4F incorporating benzotriazole moiety and intramolecular noncovalent interactions has led to a record PCE of 13.8% for UFAs, demonstrating the great potential of UFAs for high performance OSCs.

Ruijie Ma et al.

Summary: This article introduces highly efficient ternary OSCs based on PM6:BTP-ClBr1:BTP-2O-4Cl-C12, with 16.68% power conversion efficiency for as-cast device, relatively close to its annealed counterpart. The improved PCE of ternary device is mainly attributed to improved morphological properties including the more favorable materials miscibility, crystallinity, domain size and vertical phase separation. These results provide understanding and guidance for high-performance as-cast OSCs through the ternary strategy.

16% efficiency all-polymer organic solar cells enabled by a finely tuned morphology via the design of ternary blend

Tao Liu et al.

Summary: The performance of all-polymer organic solar cells has been improved by introducing a small amount of BN-T, resulting in increased crystallinity and enhanced exciton harvesting and charge transport. This enhancement is attributed to the reduced nonradiative energy loss and improved energy and charge transfer between acceptors, making AP-OSCs potentially as efficient as devices based on small molecule acceptors.
