Organic solar cells (OSCs) based on a bulk heterojunction structure exhibit inherent advantages, such as low cost, light weight, mechanical flexibility, and easy processing, and they are emerging as a potential renewable energy technology. However, most studies are focused on lab-scale, small-area (<1 cm) devices. Large-area (>1 cm) OSCs still exhibit considerable efficiency loss during upscaling from small-area to large-area, which is a big challenge. In recent years, along with the rapid development of high-performance non-fullerene acceptors, many researchers have focused on developing large-area non-fullerene-based devices and modules. There are three essential issues in upscaling OSCs from small-area to large-area: fabrication technology, equipment development, and device component processing strategy. In this review, the challenges and solutions in fabricating high-performance large-area OSCs are discussed in terms of the abovementioned three aspects. In addition, the recent progress of large-area OSCs based on non-fullerene electron acceptors is summarized.
基于体异质结结构的有机太阳能电池（OSC）具有成本低、重量轻、机械柔韧性好和易于加工等固有优势，正成为一种有潜力的可再生能源技术。然而，大多数研究集中在实验室规模的小面积（<1平方厘米）器件上。大面积（>1平方厘米）的有机太阳能电池在从小面积扩大到大面积的过程中仍表现出相当大的效率损失，这是一个巨大的挑战。近年来，随着高性能非富勒烯受体的快速发展，许多研究人员专注于开发大面积的非富勒烯基器件和模块。将有机太阳能电池从小面积扩大到大面积有三个关键问题：制造技术、设备开发和器件组件加工策略。在这篇综述中，将从上述三个方面讨论制造高性能大面积有机太阳能电池时面临的挑战和解决方案。此外，还总结了基于非富勒烯电子受体的大面积有机太阳能电池的最新进展。
