Two major challenges need to be overcome to bridge the efficiency gap between small-area rigid organic solar cells (OSCs) and large-area flexible devices: the first challenge lies in preparing high-quality flexible transparent electrodes with low resistance, high transparency, smooth surface, and superior mechanical properties. Second, the scalable fabrication of thickness-insensitive photoactive layers with low-cost materials is also an essential task. In this review, recent progress and challenges of flexible large-area OSCs are summarized and analyzed. Based on our analysis, strategies and opportunities are proposed to promote the development of stable and efficient flexible large-area OSCs.

要弥合小面积刚性有机太阳能电池 (OSC) 和大面积柔性器件之间的效率差距，需要克服两个主要挑战：第一个挑战在于制备具有低电阻、高透明度、光滑度的高质量柔性透明电极。表面和优异的机械性能。其次，用低成本材料可扩展地制造厚度不敏感的光敏层也是一项基本任务。在这篇综述中，总结和分析了柔性大面积 OSC 的最新进展和挑战。基于我们的分析，提出了促进稳定高效柔性大面积OSC发展的策略和机遇。
