Abstract Organic photovoltaic devices fabricated with polythiophenic derivatives and single-walled carbon nanotubes (SWCNT)s have been assembled and tested. For this purpose, some new regioregular polythiophenes with different sulfur-containing groups in the terminal position of a hexamethylenic side chain were prepared using direct and indirect polymerization routes. The optical features of the synthesized
摘要组装并测试了由聚噻吩衍生物和单壁碳纳米管(SWCNT)制成的有机光伏器件。为此,使用直接和间接聚合路线制备了一些在六亚甲基侧链的末端具有不同含硫基团的区域规则的聚噻吩。通过记录它们在不同溶剂/非溶剂系统和薄膜中的UV-Vis光谱,对合成聚合物的光学特性进行了检查和比较。仔细分析了它们的热稳定性,电导率,循环伏安法和光伏性能。特别是,两个在侧链上带有亚磺酰基的样品表现出更好的色度响应,增强的自组装能力,更长的结合长度,
