A pyrene-fused dimerized electron acceptor has been successfully synthesized and subsequently incorporated as the third component in ternary organic solar cells (OSCs). Diverging from traditional acceptors with a linear configuration, this novel displays distinctive "butterfly-like" structure, comprising two Y-acceptors wings fused pyrene-based backbone. The extended π-conjugated backbone electron-donating nature of pyrene enable new to show low solubility, elevated glass transition...
For the first time, formamidinium–caesium perovskite thin films were successfully synthesised from a lead acetate-based precursor. Efficient solar cells (21.0%) and modules (18.8%) have been produced using blade coating techniques.
The incorporation of insulating polymers into conjugated has been widely explored as a strategy to improve mechanical properties flexible organic electronics. However, phase separation due the immiscibility these limited their effectiveness. In this study, we report discovery multiple non-covalent interactions that enhances miscibility between and polymers, resulting in improved properties. Specifically, have added polyvinyl chloride (PVC) polymer PM6 observed significant increase solution...
We report a low-temperature processed, hydroxyl-free poly(vinyl phenyl) (PVP) dielectric layer cross-linked using thiol–ene chemistry. This new material exhibited high constant as compared to conventional polymer dielectrics, e.g. polystyrene, and allowed for cross-linking at 80 °C, which is lower than the glass transition temperature of most commonly used plastic substrates, poly(ethylene terathalate) (PET). Due absence hydroxyl groups, displayed more stable performance other previously...
An organic semiconductor with high carrier mobility and efficient light absorption over a wide spectral range is of the most important yet challenging material for constructing broadband responsive photodetector. However, development such semiconductors, especially air-stable n-type small molecule still at an early stage. Here we report fabrication high-performance semiconducting crystalline nanosheets field-effect transistors, phototransistors, response broad spectrum. The assembled into...
Novel defect-related hydroxyapatite (DHAP), which combines the advantages of HAP and luminescence, has potential application in tissue engineering biomedical area, because its excellent capability monitoring osteogenic differentiation material biodegradation. Although extracellular mechanism DHAP minerals PO43– functioning been widely studied, intracellular molecular through mediates osteogenesis bone mesenchymal stem cells (BMSCs) is not clear. We examined a previously unknown promoted...
Polymerized small-molecule acceptors (PSMAs) have made significant progress as the application in all-polymer solar cells (all-PSCs). Most PSMAs are constructed by near-infrared fused-ring electron via Stille polymerization, such Y-series acceptors. However, very limited non-fused with simplified synthetic complexity been used PSMAs. In this work, two a benzothiadiazole (BT) core developed for all-PSCs. The S-O non-covalent interaction and regioregularity introduced to improve crystallinity...

In this work, the first dimerized nonfused electron acceptor (NFEA), based on thieno[3,4-c]pyrrole-4,6-dione as core, has been designed and synthesized. The its single counterpart exhibit similar energy levels but different absorption spectra due to their distinct aggregation behavior. acceptor-based organic solar cells (OSCs) demonstrate a higher power conversion efficiency of 11.05%, accompanied by enhanced thermal stability. This improvement is attributed enhancement short-circuit current...
The J-aggregates of perylene bisimide are successfully applied as cathode interlayers in inverted photovoltaic devices to afford very high power conversion efficiency (PCE).
Non-fused near-infrared electron acceptors based on a naphthobistriazole core were developed for organic solar cells with efficiencies over 10%.
Nonfused electron acceptors have recently attracted considerable attention, primarily owing to their inherent merits, which encompass straightforward synthetic methodologies, heightened yield efficiencies, and economic viability. In this study, we undertaken the deliberate design synthesis of two distinct nonfused acceptors, denoted as BTIC-4F PTIC-4F, featuring a two-dimensional (2D) extended electron-deficient quinoxaline moiety central core 4H-cyclopenta[1,2-b:5,4-b′]dithiophene (CPDT)...

Double-cable conjugated polymers have been successfully applied into single-component organic solar cells (SCOSCs) in recent years. The chemical structures of backbones and aromatic cable units, the rational tuning nanophase separation between them, are clue factors for double-cable to further enhance photovoltaic performance. In this work, we introduced a benzothiadiazole (BT) unit backbone polymers, where BT was with two linkers, thiophene thienothiophene, which were used control...
Abstract Head‐to‐tail regioregular poly(3‐heptanoylthiophene) (PHOT) was synthesized by Ni‐catalyzed polycondensation of the 2,2‐dimethyl‐1,3‐propanediol‐protected Grignard monomer followed deprotection. Cyclic voltammetric (CV) study demonstrates that highest occupied molecular orbital (HOMO) and lowest unoccupied (LUMO) PHOT are 0.5 eV lower in energy than those head‐to‐tail poly(3‐hexylthiophene) (HT‐P3HT). Their optical band gaps essentially same. Incomplete photoluminescence (PL)...
