Summary. In this work, a non-fullerene acceptor DTY6 is designed to apply in organic solar cell (OSC) module devices. When blended with donor PM6, the DTY6 …
In single-component organic solar cells, the double-cable polymers provide power conversion efficiency up to 4.18%. This is one of the highest performances in single-component organic solar cells. The nanophase-separated design can likely be used to achieve ...
Bimolecular recombination, and hole traps constrain single component Y6 photovoltaics to low efficiencies, but recombination is reduced by small quantities of donor.
Single-component organic solar cells (SCOSCs), which contain only one photoactive material in their active layers, promise many advantages with respect to the …
The high efficiency all-small-molecule organic solar cells (OSCs) normally require optimized morphology in their bulk heterojunction active layers. Herein, a small-molecule donor is designed and ...
With this method, a series of double-cable conjugated polymers with different fullerene contents were developed and applied into single-component organic solar cells. The power conversion efficiencies (PCEs) based on these polymers increased from 0.71% to 1.71% with the enhanced fullerene contents.

Thanks to the emerging non-fullerene acceptors (NFAs), power conversion efficiencies (PCEs) of bulk heterojunction (BHJ) organic solar cells (OSCs) continue increasing towards the 20% milestone. Nevertheless, important factors for industrial application are mostly neglected, such as photostability and cost potential. Single-component organic solar …

A double-cable conjugated polymer DCPIC-BO with long-branched alkyl chains 2-buthyloctyl on the acceptor side unit was designed and applied into single-component organic solar cells. As a result, PCEs of ∼9.7% were obtained via DCPIC-BO-based devices processed from non-halogen solvents (o-XY and THF) at a mild temperature.
Single-component organic solar cells (OSCs) use one conjugated material as a photo-active layer, which can enhance the stability of cells and simplify the fabrication process compared to two-component OSCs. Among single-component conjugated materials ...
The thin film morphology of double-cable conjugated polymers is critical to the performance of single-component organic solar cells (SCOSCs). Here, we explore the effect of thin film crystallinity on device performance by varying the thermal annealing temperature used during device fabrication.
