Large-area flexible devices demonstrate a notable efficiency of 14.20 % and substantially enhanced mechanical flexibility. Dual-layer organic solar cells (OSCs), fabricated through sequential-casting with separately dissolved donor and acceptor materials, offer simplified solution preparation and morphology control.
D18:D18-Cl:L8-BO ternary organic solar cells (TSCs) with dual-donor are fabricated, and the highest power conversion efficiency (PCE) of 19.13% is achieved. The open circuit voltage of D18:D18-Cl:L8-BO TSCs is 0.915 V, the short circuit current density is 26.22 mA cm −2, and the fill-factor is 79.75%.
Nature Nanotechnology 17, 53–60 (2022) Cite this article Although the multiple-component (MC) blend strategy has been frequently used as a very effective way to improve the performance of organic solar cells (OSCs), there is a strong need to understand the fundamental working mechanism and material selection rule for achieving optimal MC-OSCs.
Finally, we evaluated the long-term stability and the universality of the dual-donor induced crystallinity modulation strategy. Device stability is crucial for solar cell performance [50, 51]. As shown in Fig. S14, after 800 h of indoor light exposure, the ternary device retains 82% of its initial PCE.
The dual-donor strategy for modulating the crystallinity of the active layer is applicable to a variety of Y6 derivatives, and the increase in PCE exceeds 1%. Trap-assisted charge recombination is one of the primary limitations of restricting the performance of organic solar cells.
