摘要

聚合物太阳能电池因其易于加工、可制备成柔性器件、材料来源广泛等优点得到材料界和能源界的广泛关注。有机太阳能电池效率的不断提高主要得益于材料的发展和电池器件结构的优化。从材料设计角度考虑，种类众多的给体和受体单元被开发用来构建有机共轭分子，其中，苯并噻二唑单元由于共轭平面较大和吸电子性较强的特性被广泛用于构建高性能的有机太阳能电池材料。基于此，本文首先介绍了苯并二噻吩单元及其衍生物常见的合成方法，随后总结了其在构建聚合物给体方面的应用，最后对其后续发展方向和前景提出了展望。

Abstract

Organic solar cells (OSCs) have attracted considerable interests from both academic and industrial community over the past decade due to the potentials such as low cost

tunable flexibility and high specific weight. The design of novel organic donors and optimization of device structures have helped to boost the power conversion efficiency to over 10 %. From the aspect of the material design

a wide variety of donor and acceptor units were developed to build the organic conjugated donors. Among which

benzothiadiazole (BT) unit is widely used in constructing high-efficiency OSCs materials due to its large conjugate plane and strong electron-withdrawing properties. In this review

we present an overview the recent progress of the BT-based organic photovoltaic materials and their application in OSCs.
