In recent decades, the demand for clean and renewable energy has grown increasingly urgent due to the irreversible alteration of the global climate change. As a result, organic solar cells (OSCs) have emerged as a promising alternative to address this issue. In this review, we summarize the recent progress in the molecular design strategies of benzodithiophene (BDT)-based polymer and small molecule donor materials since their birth, focusing on the development of main-chain engineering, side-chain engineering and other unique molecular design paths. Up to now, the state-of-the-art power conversion efficiency () of binary OSCs prepared by BDT-based donor materials has approached 20%. This work discusses the potential relationship between the molecular changes of donor materials and photoelectric performance in corresponding OSC devices in detail, thereby presenting a rational molecular design guidance for stable and efficient donor materials in future.
近几十年来，由于全球气候变化的不可逆转，对清洁和可再生能源的需求变得越来越迫切。因此，有机太阳能电池（OSCs）已成为解决这一问题的有前途的替代方案。在这篇综述中，我们总结了自诞生以来基于苯并二噻吩（BDT）的聚合物和小分子供体材料的分子设计策略的最新进展，重点关注主链工程、侧链工程和其他独特分子设计路径的发展。到目前为止，由基于BDT的供体材料制备的二元有机太阳能电池的最高功率转换效率（）已接近20%。这项工作详细讨论了供体材料的分子变化与相应有机太阳能电池器件中的光电性能之间的潜在关系，从而为未来稳定高效的供体材料提供合理的分子设计指导。
