792 Dye-sensitized Solar Cells with Halide-bridged Mixed-valence Cu(I)­Cu(II) Coordi-nation Polymers with Hexamethylenedithio-carbamate Ligand

The application of halide-bridged mixed-valence Cu(I)−Cu(II) coordination polymers withhexamethylenedithiocarbamate (Hm-dtc) ligand is novel as sensitizing materials for dye-sensitized solar cells (DSSCs) with poly(3,4-ethylenedioxythiophene) tetramethacrylate(PEDOT-TMA) counter electrode.
