Organic photovoltaics (OPVs) suffer from a trade-off between efficient charge transport and suppressed nonradiative recombination due to the aggregation-induced luminance quenching of organic semiconductors. To resolve this grand challenge, a π-extended nonfullerene acceptor (NFA) B6Cl with large voids among the honeycomb …
Performance of nonfullerene-based organic solar cells is largely dependent on the donor:acceptor blend morphology, which is initially tuned by composition. However, morphological design rules are difficult to identify due to the complex relationship between composition-dependent phase behavior and performance properties.
Nature Communications - High-performance organic solar cells call for novel designs of acceptor molecules. Here, He et al. design and synthesize a non-fullerene acceptor with an...
Organic solar cells (OSCs) have entered the era of non-fullerene electron acceptors. Nowadays with the rapid development of …
The active layer of organic solar cells (OSCs) is composed of a p-type conjugated polymer as the donor and an n-type organic semiconductor as the acceptor.Since the report of bulk-heterojunction OSCs with soluble C 60 derivative PCBM as the acceptor in 1995, fullerene derivatives, including PCBM and the C 70 derivative …
Non-fused ring electron acceptors may have low synthetic costs but also exhibit poor crystallinity in organic solar cells. Zeng et al. use a binary solvent system to control the crystallization ...

A novel planar acceptor IDT-2BR was designed and synthesized. Polymer solar cells (PSCs) based on P3HT:IDT-2BR blended films gave power conversion efficiencies of up to 5.12%, which are much higher than that of PC61BM-based control devices (3.71%) and the highest values reported for P3HT-based fullerene-free
This article describes about 18% efficiency org. solar cells, these nonfullerene acceptors have strong visible-NIR light-harvesting capability and good electron mobility, delivering higher short-circuit c.d. …
A new polymer acceptor PZC24 and its "twins" dimer acceptor CH-D1 are designed and reported. By introducing CH-D1 into the PM6:PZC24, impressive power conversion efficiencies (PCEs) of 17.40% for rig... Developing efficient and …
6 · The strategy of isomerization is known for its simple yet effective role in optimizing molecular configuration and enhancing the power conversion efficiency (PCE) of organic solar cells (OSCs). However, the impact of isomerization on the design of …
Non-fullerene acceptors (NFAs) are currently a major focus of research in the development of bulk-heterojunction organic solar cells (OSCs). In contrast to the …
