制备了铜酞菁衍生物和二酰亚胺衍生物为工作物质的双染料有机光伏体系,讨论了工作物质分子结构对体系中载流子(电子和空穴)传输过程的影响,认为带有吸电子侧基的给体分子与带有推电子侧基的受体分子组合成的有机光伏体系可能更有利于载流子的转移和传输,从而在一定程度上提高体系的光电转换性能。最后,尝试从量子化学的角度对体系的光电转换性能进行了解释。
Two-dye organic photovoltaic system was prepared by using copper phthalocyanine derivatives and stilbene derivatives as working materials. The influence of molecular structure of working materials on the transport of carriers (electrons and holes) in the system was discussed. The organic photovoltaic system composed of donors with pendant electron-attracting groups and acceptor molecules with pendant electron-pushing groups may be more conducive to the transfer and transport of carriers, thus improving the photoelectric conversion performance of the system to a certain extent. Finally, attempts to explain the photoelectric conversion performance of the system from the quantum chemistry point of view.
