【摘要】 有机太阳能电池由于其柔性可弯曲且可实现大面积生产等优点受到广泛关注^[1-2],目前,提高有机太阳能电池稳定性是实现其商业化应用的一个关键性问题^[3]。本课题研究了包括P3HT:PCBM,P3HT:Bis-PCBM,PTB7-Th:PCBM等倒置有机太阳能电池在不同输出情形下（开路,短路和不同负载）衰减行为,结果表明器件的衰减过程与外接负载具有密切的依赖性（图1a）。据此,我们推断光照条件下光伏器件产生的内建电场进而诱导受体分子的迁移是导致器件衰减的最主要原因。本报告将详细介绍相关的机理研究结果（图1b）。更多还原

【Abstract】 Owing to the advantages of mechanical flexibility and large area fabrication, organic solar cells have gained great attention. Currently, the question of long-term stability remains one of key challenges for successful commercialization of OSCs. External load depended degradation behaviors of inverted P3HT:PCBM, P3HT:Bis-PCBM, PTB7-Th:PCBM were investigated carefully in our research groups(Figure 1a), and results showed that photon generated build-in potential induced molecule motions is the main reason for the degradation(Figure 1b). Detailed experiment results as well as the degradation mechanism will be reported in this presentation.更多还原
