Abstract Organic solar cells (OSCs) have experienced rapid progress with the innovation of near‐infrared (NIR)‐absorbing small‐molecular acceptors (SMAs), while unique electronic properties SMAs raise new challenges in relation to cathode engineering for effective electron collection. To address this issue, two fluorinated perylene‐diimides (PDIs), PDINN‐F and PDINN‐2F, are synthesized by a simple fluorination method, application as interlayer (CIL) materials. The bay‐fluorinated PDI‐based CILs possess lower lowest unoccupied molecular orbital (LUMO) energy level ≈−4.0 eV, which improves alignment at NIR‐SMAs (such BTP‐eC9)/CIL favorable extraction efficiency. monofluorinated shows higher mobility better improved interfacial compatibility. PDINN‐F‐based OSCs PM6:BTP‐eC9 active layer exhibit an enhanced fill factor larger short‐circuit current density, leading high power conversion efficiency (PCE) exceeding 18%. devices CIL retain more than 80% their initial PCE after operating maximum point under continuous illumination 750 h. This work prescribes facile, cost‐effective, scalable method preparation stable, high‐performance CILs, instilling promise NIR‐SMAs‐based moving forward.

The field of organic solar cells (OSCs) has acquired rapid progress with the development nonfullerene acceptors. Interfacial engineering is also significant for enhancement power conversion efficiency (PCE) in OSCs. Among cathode interfacial materials (CIMs), perylene diimide (PDI) small molecules are promising owing to excellent electron affinity and mobility. Although well-known PDINN molecule properties, it a high planarity formed by an extensive rigid π-conjugated backbone. Because PDI molecular backbone strong tendency aggregate, causes problem excessive aggregation stacking, which directly leads crystallinity. Proper accumulation beneficial charge transport, but oversized crystals overaggregation will hinder ultimately affecting film morphology transport efficiency. Modifying bay position effective strategy reduce planarity, modulate aggregation, optimize morphology, enhance charge-collecting Therefore, PDINN-S was synthesized from substituting hydrogen thiophene. optimal PCE PM6:Y6 active layer 16.18% remained at 80% initial value after 720 h glovebox.
