摘要

氟化多壁碳纳米管是有机太阳能电池活性层的第三种成分。在 PCDTBT/PC60BM 聚合物/富勒烯活性层中加入约 1%重量分数的这些纳米管后，太阳能电池的主要光电参数，包括其稳定性都有了显著提高。据推测，这种影响的根源在于优化了供体/受体复合形态，并用氟化多壁碳纳米管强化了其结构。含氟多壁碳纳米管添加剂对 PCDTBT/PC60BM 复合材料中光诱导电荷的 EPR 信号衰减动力学的巨大影响支持了这一假设。

Ternary Composite of Polymer, Fullerene and Fluorinated Multi-Walled Carbon Nanotubes as the Active Layer of Organic Solar Cells

Fluorinated multi-walled carbon nanotubes are implemented as the third component of the active layer of organic solar cells. The addition of approximately 1% weight fraction of these nanotubes into PCDTBT/PC60BM polymer/fullerene active layer leads to a noticeable increase in the main photovoltaic parameters of the solar cells, including their stability. Presumably, the origins of this influence are optimizing the donor/acceptor composite morphology and reinforcing its structure with fluorinated multi-walled carbon nanotubes. This hypothesis is supported by the dramatic influence of the fluorinated multi-walled carbon nanotube additive on the kinetics of the decay of the EPR signal of light-induced charges in the PCDTBT/PC60BM composite.
