Dye-sensitized solar cell by using dye of the food produced in Okinawa
Taisuke Hamada
Department of Bioresources Engineering
Dyes which were obtained from the food produced in Okinawa were applied as a sensitizer in dye-sensitized solar cell. The dyes acted as a sensitizer of the solar cell under irradiation (AM 1.5G). This was confirmed by the measurements of the wavelength dependence of the current under irradiation.
