Abstract

The green and purple dyes that were obtained from the two-colored Gynura bicolor were applied as a sensitizer in a dye-sensitized solar cell.  These dyes acted as a sensitizer of the solar cell under irradiation (AM 1.5G).  The efficiency of the cell using purple dye was higher than that of the cell using green dye.  However, the efficiency of the cell that used both dyes for a sensitizer was greater as compared with cells that used either dye individually for sensitizers.
