Compared with inorganic photovoltaic technologies, flexibility is the most prominent feature of organic solar cells (OSCs). Flexible OSCs have been considered as one of the most promising directions in the OSC field, and have drawn tremendous attention in recent years. However, the power conversion efficiencies (PCEs) of flexible OSCs still lag behind those of their rigid counterparts. To further improve the performance of flexible OSCs, it is of great necessity for synergistic efforts to optimize flexible transparent electrodes (FTEs), photoactive materials, electrode buffer layers, and device structure engineering. Herein, the recent progress in flexible OSCs from the perspective of FTEs, including indium tin oxides, carbon nanomaterials, conducting polymers, silver nanowires, and ultrathin metal films and metal meshes, is summarized. In addition, the photoactive materials and electrode buffer layers in flexible OSCs are discussed to reveal the effects of material engineering and interface modification. Finally, a discussion of the future outlook and challenges of flexible OSCs is presented.
与无机光伏技术相比，灵活性是有机太阳能电池（OSC）最突出的特点。柔性有机太阳能电池被认为是有机太阳能电池领域最有前途的方向之一，近年来受到了极大的关注。然而，柔性有机太阳能电池的功率转换效率（PCE）仍落后于刚性有机太阳能电池。为了进一步提高柔性有机太阳能电池的性能，协同优化柔性透明电极（FTE）、光活性材料、电极缓冲层和器件结构工程非常必要。在此，从FTE的角度总结了柔性有机太阳能电池的最新进展，包括铟锡氧化物、碳纳米材料、导电聚合物、银纳米线以及超薄金属膜和金属网格。此外，还讨论了柔性有机太阳能电池中的光活性材料和电极缓冲层，以揭示材料工程和界面改性的影响。最后，对柔性有机太阳能电池的未来前景和挑战进行了讨论。
