采用湿化学方法合成共价键结合的酞菁-苝给受体结构(PcCu-4SBPTCD)及其原位修饰多壁碳纳米管(MWCNTs)的复合材料,并研究复合材料内部的电荷传输性能。结果表明,酞菁-苝给受体结构中,酞菁和苝之间有明显的电荷传输,即合成的酞菁-苝给受体结构能有效提高电子空穴的分离效率。在该给受体结构中引入多壁碳纳米管能更进一步地提高电子空穴的分离效率。将碳纳米管-酞菁-苝(MWCNTs-PcCu-4SBPTCD)用于组装有机太阳能电池(OSCs),有望大大提高电池的光电转换效率。
The wet chemical method was used to synthesize the composite of phthalocyanine-perylene acceptor (PcCu-4SBPTCD) and in-situ modified MWCNTs. The charge transport properties of the composites were also studied. The results show that the phthalocyanine - perylene acceptor structure, phthalocyanine and perylene between the significant charge transfer, that is, the synthesis of phthalocyanine - perylene donor structure can effectively improve the electron - hole separation efficiency. The introduction of multi-walled carbon nanotubes into the acceptor structure can further improve the electron-hole separation efficiency. The use of carbon nanotubes-phthalocyanine-perylene (MWCNTs-PcCu-4SBPTCD) for the assembly of organic solar cells (OSCs) is expected to greatly improve the photoelectric conversion efficiency of the cell.
