All-polymer solar cells (all-PSCs) can offer unique advantages for applications in flexible devices, and naphthalene diimide (NDI)-based polymer acceptors are the widely used acceptors. However, their power conversion efficiency (PCE) still lags behind that of state-of-the-art cells, due to low light absorption, suboptimal energy levels strong aggregation NDI-based acceptor. Herein, a rhodanine-based dye molecule was introduced into acceptor by simple random copolymerization showed an...
Abstract Fabricating ternary solar cells is a pivotal strategy to improve the power conversion efficiencies (PCEs) of organic photovoltaic devices. However, it still challenge simultaneously performance parameters Therefore, third ingredient in blends should be precisely designed or selected. Herein, new medium‐bandgap small‐molecule acceptor, namely,...
Similar structural of BDT-SiCl and BDT-2F can minimize the disturbance molecular orderly packing caused by random copolymerization, then terpolymer-based OSCs yielding overall improved device parameters than PM6-based device.
D–A polymers exhibit excellent intramolecular charge transfer (ICT) properties due to the differences in energy levels. However, bulky dihedral angles between D and A units with conjugated structures have a negative impact on process of ICT, which inhibits efficient electron transport adjacent units. To solve this problem, noncovalent conformational locks were constructed by introduction π-bridges. Intriguingly, thiophene π-bridges containing sulfur elements can form S─H locks, not only...
Although benzoazole‐fused rings with strong quinoid character have successfully been used to construct high‐performance small‐molecule non‐fullerene acceptors (NFAs), studies into how these units influence the stabilities of NFAs and their corresponding device performances are few date. To address it, four new NFAs, SSTI, SNTI, NTI NTTI, which adopt BBT, TBZ, BTAZ as cores, respectively, designed investigated. It is found that SSTI SNTI based on BBT TBZ cores stronger resonance effects show...
Simultaneously enhancing the power conversion efficiency (PCE) and stability of organic solar cells (OSCs) is a pivotal issue to advance their commercial feasibility. The frequently used cathode interface layer (CIL) based on perylene diimide (PDI) derivatives usually causes some problems, such as unmatched surface energies (γs) with an active layer, strong aggregation, poor stability. Herein, bay amide position synergistically benzoyl hydrazide-functionalized PDI-based CILs, namely...
Currently, photothermal (PT) polymers are gaining increasing attention in water evaporation, photocatalysis and therapy. However, high-performance PT often require conjugated backbones and/or large fused units, which can impede non-radiative decay lead to suboptimal performance. The development of general strategies for preparing remains a significant challenge. In this paper, the donor–acceptor (D–A) random copolymers, named PBT4T-BBT-x (x = 0, 5, 10, 20 100), were fabricated by...
Abstract Cathode interface layers (CILs) are crucial for optimizing the power conversion efficiency (PCE) and stability of organic solar cells (OSCs). Two small molecule CILs, PDINN‐TS PDINN‐BS developed, by modifying bay sites perylene diimide (PDI) with thieno [3,2‐b] thiophene 2,2′‐bithiophene, separately. Due to better electron‐donating capacity longer conjugate length exhibits a stronger self‐doping effect superior compatibility compared PDINN‐TS. Consequently, in PM6: Y6 OSCs, achieved...
Organic solar cells (OSCs) usually need to be optimized with the strategies of thermal annealing (TA), solvent vapor (SVA), or processing additives (PA) obtain best performance. Here, PA and TA were used simultaneously for OSCs based on novel organic molecules TBDT-T6ffBT OBDT-T6ffBT. The synergistic effect active-layer morphologies was investigated by measurements optical microscopy, atomic force transmission electron grazing incident X-ray diffraction. Comprehensive results suggest that a...
Continuous breakthroughs have been achieved in improving the efficiency of all-polymer solar cells (all-PSCs) using diimide-based polymer acceptors, and their easy-to-synthesize, low-cost, high stability attributes make them potential candidates for use commercial all-PSCs. However, low light absorption coefficient, strong aggregation, poor adaptability with high-efficient donors still limit further improvements device performance. Here, we combine advantages fluorinated bithiophene...
Two quasi-three-dimensional self-doped conjugated polyelectrolytes based on a triphenylamine skeleton are designed and employed as ETLs to modulate the cathode interface for efficient non-fullerene organic solar cells.
