Abstract Dimeric acceptor (DMA) becomes a promising alternative to small‐molecular and polymeric acceptor‐based organic solar cells (OSCs) due its well‐defined chemical structure, high batch‐to‐batch reproducibility, low molecular diffusion properties. However, DMAs usually exhibit blueshifted absorptions, limiting their photon utilization abilities. Herein, multi‐selenophene strategies are adopted develop redshifted DMAs. From monomer (YSe) dimers (DYSe‐1 DYSe‐2), reduced electron...

Abstract To enhance the performance of dimeric acceptors (DMAs) based organic solar cells (OSCs), two new DMAs, designated as DC9‐HD and DYSe‐3, are rationally developed employed to fabricate ternary OSCs. The substitution sulfur atom on outer ring fused‐ring core with a selenium resultes in red‐shifted DYSe‐3. Despite these minor differences, DYSe‐3 possess nearly identical conjugated skeletons, which contribute their similar packing motifs crystallinities, ultimately enabling high degree...

Comprehensive Summary Small‐molecular organic solar cells usually exhibited unsatisfactory device stability, which might originate from their molecular diffusion behaviors. Herein, based on the all‐small‐molecule system HD‐1:BTP‐eC9, we reported a dimerized acceptor DC9, and its corresponding monomer eOD. In comparison with eOD, dimeric DC9 displayed higher glass transition temperature ( T g ) but reduced planarity crystallinity. The all‐small molecule blend utilizing HD‐1:eOD demonstrated...

Abstract Disordered polymer chain entanglements within all‐polymer blends limit the formation of optimal donor–acceptor phase separation, and thus performance organic solar cells (all‐PSCs). Considering challenge importance morphology regulation in all‐PSCs, a diluted layer‐by‐layer (N‐LBL) strategy is thereby adopted to fine‐tuning properties blends. When comparing traditional PM6:PY‐IT based bulk‐heterojunction (BHJ) film PM6/PY‐IT (LBL) film, N‐LBL which prepared from PM6 (with 3% PY‐IT)...

Many real-world multiple-objective optimization problems have objectives that change over time. These are called dynamic (DMOPs) and received an increased attention. To track the changing Pareto front in DMOPs, at a certain moment needs to be obtained as efficiently possible, which is challenging for most of existing methods. this end, we propose two-level parallel decomposition-based artificial bee colony method solving DMOPs. sufficiently accelerate process obtaining front, structure...

Taxonomies play a crucial role in various applications by providing structural representation of knowledge. The task taxonomy expansion involves integrating emerging concepts into existing taxonomies identifying appropriate parent for these new query concepts. Previous approaches typically relied on self-supervised methods that generate annotation data from taxonomies. However, are less effective when the is small (fewer than 100 entities). In this work, we introduce \textsc{CodeTaxo}, novel...
