摘要
有机光伏技术为太阳能的有效利用提供了一条重要途径。有机太阳能电池因制造成本低廉、材料质量轻、加工性能好、易于携带等优势而备受关注。提高有机太阳能电池的光电转换效率是目前乃至未来的研究重点。设计和合成适合的窄带隙的共轭聚合物是提高有机太阳能电池光电转化效率的核心。综述了近年来基于窄带隙的共轭聚合物的太阳能电池材料的设计、制备和器件性能研究进展,探讨了目前存在的亟待解决的关键基础问题和未来发展方向。
Organic photovoltaic technology provides an essential way for the effective utilization of solar energy. The advantages of polymer solar cells （PSCs） include low cost, light weight, easy fabrication, flexible and tunable properties. There is increasing interest in PSCs during the last few years, however, the power conversion efficiency （PCE） of PSCs far beyond practical requirements. Upon this, design and synthesis of appropriately low bandgap polymers and probing into the mechanisms become the extremely interesting topics in the field of high efficiency PSCs. In this contribution, the basic concept and the opera- tion mechanism of PCSs, the progress of polymer materials and the problems that needs to be solved urgently in the near future were systematically reviewed.
