摘要:

柔性是有機太陽能電池最為顯著的特點和優勢。但是，目前柔性有機太陽能電池的性能仍然滯后于剛性器件，這主要是因為缺乏同時具有低電阻、高透光度和低表面粗糙度的高性能柔性透明電極。傳統的氧化銦錫透明電極因其脆性以及銦元素的稀缺，限制了其在柔性器件中的發展與應用。因此，開發新型、高性能的柔性透明電極是柔性有機太陽能電池發展和應用的基礎。在新型的柔性透明導電材料中，金屬納米線，特別是銀納米線（AgNWs），以其優異的綜合光電性能和柔韌性成為柔性透明電極中的明星導電材料。同時，基于AgNWs柔性透明電極構筑柔性有機太陽能電池也被廣泛研究，并取得了一系列進展。綜述了近年來基于AgNWs透明電極的柔性有機太陽能電池的研究進展，重點介紹了AgNWs柔性透明電極的性質對柔性有機太陽能電池性能的影響，并對未來的研究方向進行了展望。

Abstract:

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.
