Dye-sensitized solar cells are expected to be used as future clean energy. Most of the researchers in the field of the dye-sensitized solar cells use Ruthenium complex as dye. On the other hand, we have proposed the dye-sensitized solar cells using natural dyes, such as dye of red-cabbage and curcumin. In this paper, we use new electrolyte solution for the solar cells using dye of curcumin. As a result, a conversion efficiency of about 1.3% has been obtained (light source: halogen lamp).
