Abstract

Organic solar cells (OSCs) have attracted attention due to their lightweight, flexibility and transparency. Recent advances in OSC materials, especially non-fullerene acceptors (NFAs), have led to marked improvements. NFAs are characterized by their tunable structures and broad absorption spectra, which enhance charge separation and overall performance. These developments make NFAs pivotal materials in advancing OSC technologies and they represent a promising alternative. The development of fused-ring acceptors (FRAs) has enabled power conversion efficiencies (PCEs) over 19 % to be achieved. Despite this success, the intricate synthesis processes and low material yields result in high production costs limiting the commercial viability of FRAs in OSCs. Conversely, non-fused-ring acceptors (NFRAs) offer significant advantages, including easier synthesis, higher yields and improved stability, facilitating the production of cost-effective OSCs. NFRA-based OSCs have provided similar PCE values to FRAs (above 19 %). The research published in recent months on FRAs – particularly NFRAs – is covered in this review.

非熔融和熔融环状非富勒烯受体

有机太阳能电池（OSC）因其轻质、灵活和透明而备受关注。有机太阳能电池材料，特别是非富勒烯受体（NFA）的最新进展带来了显著的改进。非富勒烯受体的特点是结构可调、吸收光谱宽广，可增强电荷分离和整体性能。这些发展使非富勒烯受体成为推动 OSC 技术发展的关键材料，也是一种前景广阔的替代材料。熔环受体（FRA）的开发使功率转换效率（PCE）超过了 19%。尽管取得了这一成功，但复杂的合成工艺和较低的材料产量导致生产成本居高不下，限制了 FRA 在 OSC 中的商业可行性。相反，非熔合环受体（NFRA）具有显著的优势，包括更容易合成、更高的产量和更好的稳定性，有利于生产出具有成本效益的 OSC。基于 NFRA 的 OSC 具有与 FRA 相似的 PCE 值（高于 19%）。本综述介绍了近几个月发表的有关 FRA（尤其是 NFRA）的研究成果。

期刊介绍： Current Opinion in Colloid and Interface Science (COCIS) is an international journal that focuses on the molecular and nanoscopic aspects of colloidal systems and interfaces in various scientific and technological fields. These include materials science, biologically-relevant systems, energy and environmental technologies, and industrial applications. Unlike primary journals, COCIS primarily serves as a guide for researchers, helping them navigate through the vast landscape of recently published literature. It critically analyzes the state of the art, identifies bottlenecks and unsolved issues, and proposes future developments. Moreover, COCIS emphasizes certain areas and papers that are considered particularly interesting and significant by the Editors and Section Editors. Its goal is to provide valuable insights and updates to the research community in these specialized areas.
