Recently, research on nonfullerene acceptors in organic solar cells has gradually become a hot topic due to such superior characteristics of light absorption and energy-level-convenient manipulation, multiformity of the photoactive material structures, as well as the extensive area in production compared to the fullerene derivatives. However, the nonfullerene acceptors evolved slowly before 2012 and, as a matter of fact, the power conversion efficiency values could only bear 2.0%. Strikingly, nonfullerene acceptors have developed at a fast pace since 2013, with the best device performance of 13.1% now. In this review, recent research progress on nonfullerene acceptors, including small molecules and polymers, are sorted and summarized on the basis of the different characteristics.
近年来，由于非富勒烯受体在光吸收和能级方便调控、多样的光活性材料结构以及与富勒烯衍生物相比更广泛的应用领域等方面的优越特性，其在有机太阳能电池中的研究逐渐成为热点。然而，在 2012 年之前，非富勒烯受体的发展较为缓慢，事实上，其能量转换效率值只能达到 2.0%。引人注目的是，自 2013 年以来，非富勒烯受体发展迅速，目前最佳器件性能达到 13.1%。在本综述中，根据不同的特点，对小分子和聚合物等不同种类的非富勒烯受体的最新研究进展进行了分类和总结。
