Novel dyes of branched chain polymeric metal complexes with benzodithiophene or hydroquinone derivatives as donor: synthesis, characterization, and photovoltaic performance for dye-sensitized solar cells
摘要:
AbstractIn this paper, four novel D–π–A polymeric metal Cd(II) or Zn(II) complexes with 8-hydroxyquinoline metal complex as electron acceptor (A), thiophene as π linker (π), and benzodithiophene or hydroquinone derivatives as electron donors (D) were designed and synthesized for utilization in dye-sensitized solar cells to obtain the efficiency value of up to 2.46 %.
