摘　　要：有机受供体聚合物薄膜太阳能电池的活性层是由共轭材料构成。其中含氟聚合物材料因氟原子的存在,有着优异的物理化学性质而被应用到有机太阳能电池的功能材料中,其不仅能提高有机太阳能电池的光电转化效率,还能增强电池的稳定性。目前已报道的基于含F聚合物的光伏器件(organic photovoltaic device,OPV)光电转化效率(power conversion efficiency,PCE)最高已达到12%,应用前景巨大。综述了3类受体单元上含F有机聚合物供体材料近几年的研究进展,并简要分析了F原子的个数以及所在区域位置的不同对器件性能的影响。最后对含氟共轭聚合物在有机太阳能电池未来的发展做出了展望。Donor-acceptor organic polymer solar cells are thin film solar cells made of organic conjugated materials.Fluor-polymer materials have been applied to the functional materials of organic solar cells due to their excellent physicochemical properties for presence of fluorine atoms,which can not only improve the photoelectric conversion efficiency of organic solar cells but also enhance the stability of the battery.At present,the reported photoelectric conversion efficiency based on photovoltaic devices containing F polymer has reached the highest of 12%,and the application prospect is huge.In this paper,the research progress of three kinds of acceptor units containing F-organic donor materials are reviewed in recent years.The effects of the number of F atoms and the location of the region on the performance of the device are briefly analyzed.Finally,the development of fluorine conjugated polymer organic solar cells in the future are prospected.
