摘　　要：柔性是有机太阳能电池最为显著的特点和优势。但是,目前柔性有机太阳能电池的性能仍然滞后于刚性器件,这主要是因为缺乏同时具有低电阻、高透光度和低表面粗糙度的高性能柔性透明电极。传统的氧化铟锡透明电极因其脆性以及铟元素的稀缺,限制了其在柔性器件中的发展与应用。因此,开发新型、高性能的柔性透明电极是柔性有机太阳能电池发展和应用的基础。在新型的柔性透明导电材料中,金属纳米线,特别是银纳米线(AgNWs),以其优异的综合光电性能和柔韧性成为柔性透明电极中的明星导电材料。同时,基于AgNWs柔性透明电极构筑柔性有机太阳能电池也被广泛研究,并取得了一系列进展。综述了近年来基于AgNWs透明电极的柔性有机太阳能电池的研究进展,重点介绍了AgNWs柔性透明电极的性质对柔性有机太阳能电池性能的影响,并对未来的研究方向进行了展望。Flexibility is the most distinguishing characteristic for organic solar cells(OSCs) that outweighs the inorganic photo-voltaic technologies. However, the current power conversion efficiencies(PCEs) of flexible OSCs still lag behind those of rigid counterparts. This is mainly due to the lack of high-performance flexible transparent electrodes(FTEs) that simultaneously offer low resistance, high transparency, and low surface roughness. Traditional indium tin oxide(ITO) conductive films are widely used in organic optoelectronic devices due to their excellent optoelectric properties. However, the intrinsic brittleness of ITO and the scarcity of indium have limited its development and application in flexible devices. Therefore, it is very important and urgently needed to develop new high-performance flexible transparent conductive materials and apply them to flexible OSCs. Among the various FTE materials, metal nanowires, especially silver nanowires(AgNWs), have become the star conductive material in FTEs with their excellent optoelectric properties and flexibility. Meanwhile, the flexible OSCs using AgNWs-based FTEs have also been extensively studied, and great progress has been made in the past decades. In this review, the recent progress of flexible OSCs with AgNWs-based FTEs has been summarized, focusing on the impact of the AgNWs-based FTEs properties on the performance of flexible OSCs. Finally, the prospects and challenges of flexible OSCs are discussed.
