摘要:有机太阳能电池（OSCs）具有成本低、可大规模溶液加工、轻量化和柔性等优势，近年来已引起人们的广泛关注，当前OSCs的最高光电转换效率已超过19%。然而，绝大多数OSCs材料主要是采用化石资源衍生物制造，这对OSCs的可持续发展构成了严重威胁。研究者已开展了大量关于生物质基光电材料的开发工作，并成功将这些材料用作OSCs的衬底、光敏活性层与载流子传输层。本文首先对OSCs的器件结构和工作原理进行了介绍，重点对木质素、纤维素、叶绿素等生物质基光电材料的制备及其在OSCs中的应用展开综述，最后对生物质基OSCs材料的发展方向做出了展望，旨在为后续的相关研发工作提供借鉴。

Abstract:Organic solar cells （OSCs）， with advantages of low cost， large-scale solution processing， lightweight and flexibility， have attracted wide attention in recent years. At present， the highest photoelectric conversion efficiency of OSCs has exceeded 19%. However， the great majority of OSCs materials are mainly manufactured from fossil resource derivatives， which constitutes serious threats on the sustainable development of OSCs. Researchers have carried out a lot of work on the development of biomass-based photoelectric materials， and successfully utilize these materials as OSCs substrates， photosensitive active layer， and carrier transport layers. This paper firstly introduced the device structures and working principle of OSCs. Then， the preparation and their applications in OSCs of biomass-based photoelectric materials such as lignin， cellulose， chlorophyll were reviewed. Finally， the development direction of biomass-based OSCs materials were prospected， aiming at providing references for the subsequent relevant researches and developments work.
