Dye-sensitized solar cells are expected to be used for future clean energy. Recently, most of
the researchers in this field use Ruthenium complex as dye in the dye-sensitized solar cells.
However, Ruthenium is a rare metal, so the cost of the Ruthenium complex is very high. In
this paper, various dye-sensitized solar cells have been fabricated using natural dye, such
as the dye of red-cabbage, curcumin, and red-perilla. As a result, it was found that the
conversion efficiency of the solar cell fabricated using the mixture of red-cabbage and …
