缓冲层在有机太阳能电池中的应用

摘要

有机太阳能电池的有机活化层与阴、阳极接触界面的性质对器件性能起着重要的作用。本文综述了近年来有机太阳能电池中使用的阴、阳极界面缓冲材料的类型和工作机制。结果表明,阴、阳极缓冲层的界面修饰对太阳能电池的能量转换效率、寿命和稳定性具有决定性的影响。因此,缓冲层的特性研究对器件结构的改进和性能优化具有一定的指导意义。该研究为其它缓冲层材料在有机太阳能电池中的成功应用提供了有益的实验思路。%The interface between organic active layer and anode or cathode plays an important role in the performance of organic solar cells（OSCs）.This paper reviewed the types and work mechanisms of different interface buffer layers applied in OSCs.The research results show that interface modification can improve OSCs performance including power conversion efficiency,device lifetime and stability.Thus,the research of characteristics of buffer layer is helpful for optimizing device structure and performance.Additionally,this review also provides valuable concepts of successful application of other buffer materials in OSCs.
