英文摘要
In this study, for the investigation of higher voltage DSCs, we adopted Br^-/Br_3^- as a redox pair. Br^-/Br_3^- has more positive redox level than I^-/I_3^- and its combination with TiO2 is considered to enable high voltage DSCs. We selected tris-(4, 4'- dicarboxylate-2, 2'-bipyridine) ruthenium(II) ((dcbpy)_3Ru) as a dye showing proper HOMO-LUMO level for Br^-/Br_3^- redox level and TiO_2 conduction band. Furthermore, we synthesized some (dcbpy)_2(R2bpy)Ru complexes as the dye having proper HOMOLUMO level for Br^-/Br_3^- redox level. We investigated DSC performances sensitized by these dye complexes. By using Br-/Br3- electrolyte, (dcbpy)_2(bpy)Ru-sensitized cell showed 3.5% efficiency with high Voc = 1.01 V.
