Resonant Multiple Light Scattering for Photon Harvest Enhancement in Dye-Sensitized Solar Cells

The present invention relates to a dye exhibiting multiple resonance light scattering in photoelectrode at electrode and high light collection efficiency at light scattering wavelength range. The present invention further relates to a dye-sensitized solar cell with increased efficiency. The organic dyes of the present invention exhibits more enhanced mole absorption coefficient, short-circuit current, and photoelectricity conversion efficiency in comparison with an existing organic dye used in the dye-sensitized solar cell, thereby remarkably increasing efficiency of the solar cell. In addition, it is possible to produced dye-sensitized solar cell with excellent long-term stability owing to the organic dyes of the present invention. It is also possible to produce a solar cell with high photoelectricity conversion efficiency by using titanium dioxide produced by electrostatic spraying technology using the organic dyes.
