Non-fullerene acceptors with fused-ring structures have rapidly improved the performance of organic solar cells over the past five years, but they still suffer from synthetic complexity and thus high material costs, one of the major obstacles of hindering their commercialization process. The construction of non-fused ring acceptors (NFRAs) has recently been regarded as a feasible solution due to their facile synthesis and satisfactory device performances. Thus in this concept, we highlight the important progress of NFRAs in recent years, and discuss the key relationship between molecular design strategies and device performance. Finally, we provide some potential molecular insights for the future design of high-performance NFRAs.
在过去五年中，具有稠环结构的非富勒烯受体迅速提升了有机太阳能电池的性能，但它们仍面临合成复杂性以及由此带来的高昂材料成本问题，这是阻碍其商业化进程的主要障碍之一。由于非稠环受体（NFRAs）合成简便且器件性能令人满意，其构建近来被视为一种可行的解决方案。因此，在本概念中，我们着重介绍了近年来非稠环受体的重要进展，并讨论了分子设计策略与器件性能之间的关键关系。最后，我们为高性能非稠环受体的未来设计提供了一些潜在的分子见解。
