| Outline of Final Research Achievements |
It was reported that organic dye and zinc porphyrin based dye-sensitized solar cells (DSCs) with cobalt redox electrolyte show a high overall solar light-to-electrical-conversion efficiencies with high open-circuit voltage. However, ruthenium complex based DSCs with cobalt redox electrolyte exhibit insufficient conversion efficiencies, probably due to the fast recombination reaction at the interface between the TiO2 and the electrolyte. To realize high performance dye-sensitized solar cells, we examined the synthesis of multinuclear complexes in which a donor complex is linked with a ruthenium complex dye. Structural effect of cyclometalated ruthenium complexes for the cells based on cobalt redox electrolytes was also investigated.
