The invention discloses a positive ion-containing ruthenium complex dye and a dye-sensitized solar cell prepared by the same. The ruthenium complex dye contains organic ions, and can improve photoelectric properties of the dye-sensitized solar cell. Specifically, the ruthenium complex dye can increase short-circuit current, open-circuit voltage and filling factor of the dye-sensitized solar cell, thereby obviously improving photoelectric conversion efficiency of the dye-sensitized solar cell.
