近十年来，溶液处理的单结聚合物太阳能电池（PSCs）的功率转换效率（PCE）从不足1%发展到超过9%。效率的显著提高来自于供体聚合物的合理设计和器件结构的创新。在所有新型高效给体聚合物中，PTB7是太阳能电池研究中应用最广泛的一种。本文综述了近年来PTB7太阳能电池的研究进展。详细讨论了基本性能、结构性能关系、形貌研究、界面工程和无机纳米材料的掺入。讨论了进一步提高PTB7太阳能电池性能的可能方向。
Solution processed single junction polymer solar cells (PSCs) have been developed from less than 1% power conversion efficiency (PCE) to beyond 9% PCE in the last decade. The significant efficiency improvement comes from progress in both rational design of donor polymers and innovation of device architectures. Among all the novel high efficient donor polymers, PTB7 stands out as the most widely used one for solar cell studies. Herein the recent development of PTB7 solar cells is reviewed. Detailed discussion of basic property, structure property relationship, morphology study, interfacial engineering, and inorganic nanomaterials incorporation is provided. Possible future directions for further increasing the performance of PTB7 solar cells are discussed.
