界面工程在非富勒烯太阳能电池中的研究进展

Research Progress on Interface Engineering in Non-fullerene Solar Cells

有机太阳能电池(OSCs)由于成本低、重量轻、可大面积制备等优点,已经显示出了巨大的前景。尤其是非富勒烯有机太阳能电池(NF-OSCs)的功率转换效率已超过18%。界面工程在不仅在提高器件效率,而且在器件稳定性方面也起着重要作用。有效的界面修饰可以改善载流子传输和收集效率。因此,对界面工程的研究是OSCs发展的重要途径。本文主要综述了NF-OSCs界面工程的最新研究进展,为之后界面材料的设计和改性提供方法指导。

Organic solar cells(OSCs)have shown great promise due to their low cost,light weight and large area preparation.In particular,the power conversion efficiency of non-fullerene organic solar cells(NF-OSCs)has exceeded 18%.Interface engineering plays an important role in improving device efficiency and device stability.Effective interface modification can improve carrier transport and collection efficiency.Therefore,the study of interface engineering is an important approach to OSCs development.The recent research progress on interfacial engineering of NF-OSCs was mainly reviewed,and methodological guidance was provided for the design and modification of interfacial materials thereafter.
