Organic photovoltaics (OPVs) have progressed steadily through three stages of photoactive materials development: (i) use poly(3-hexylthiophene) and fullerene-based acceptors (FAs) for optimizing bulk heterojunctions; (ii) development new donors to better match with FAs; (iii) non-fullerene (NFAs). The application NFAs an A–D–A configuration (where A = acceptor D donor) has enabled devices efficient charge generation small energy losses (Eloss < 0.6 eV), resulting in substantially higher power conversion efficiencies (PCEs) than FA-based devices. discovery Y6-type (Y6 2,2′-((2Z,2′Z)-((12,13-bis(2-ethylhexyl)-3,9-diundecyl-12,13-dihydro-[1,2,5]-thiadiazolo[3,4-e]-thieno[2″,3″:4′,5′]thieno-[2′,3′:4,5]pyrrolo-[3,2-g]thieno-[2′,3′:4,5]thieno-[3,2-b]indole-2,10-diyl)bis(methanylylidene))bis(5,6-difluoro-3-oxo-2,3-dihydro-1H-indene-2,1-diylidene))dimalononitrile) A–DA′ D–A further propelled the PCEs go beyond 15% due smaller Eloss values (∼0.5 eV) external quantum efficiencies.

State-of-art Y-series polymer acceptors are typically based on a mono-thiophene linker, which can cause some twisted molecular conformations and thus limit the performance of all-polymer solar cells (all-PSCs). Here, high-performance acceptor vinylene linkers is reported, leads to surprising changes in polymers' conformations, optoelectronic properties, enhanced photovoltaic performance. It found that thiophene or bithiophene (PY-T-γ PY-2T-γ) display significant twisting between end-groups linker units, while vinylene-based (PY-V-γ) exhibits more coplanar rigid conformation. As result, PY-V-γ demonstrates better conjugation tighter interchain stacking, results higher mobility reduced energetic disorder. Furthermore, detailed morphology investigations reveal PY-V-γ-based blend high domain purity fill factor its all-PSCs. With these, efficiency 17.1% achieved all-PSCs, highest reported for binary all-PSCs date. This work vinylene-linker superior unit build with chain conformation, beneficial aggregation efficient

Abstract Narrow‐bandgap n‐type polymers with high electron mobility are urgently demanded for the development of all‐polymer solar cells (all‐PSCs). Here, two regioregular narrow‐bandgap polymer acceptors, L15 and MBTI, electron‐deficient segments synthesized by copolymerizing dibrominated fused‐ring acceptors (FREA) distannylated aromatic imide, respectively. Taking full advantage FREA both show narrow bandgap mobility. Benefiting from more extended absorption, better backbone ordering, higher than those its regiorandom analog, L15‐based all‐PSC yields a power conversion efficiency (PCE) 15.2% when blended donor PM6. More importantly, MBTI incorporating benzothiophene‐core segment shows relatively frontier molecular orbital levels L15, forming cascade‐like energy level alignment Based on this, ternary all‐PSCs designed where is introduced as guest into PM6:L15 host system. Thanks to further optimal blend morphology balanced charge transport, PCE improved up 16.2%, which among highest values all‐PSCs. The results demonstrate that combining an imide construct provides effective approach fabricate highly efficient
