Optical Properties Of Tio2 Electrodes Sensitized By Red Cabbage Dye For Application In Dye-sensitized Solar Cells

Résumé: The dye-sensitized solar cell (DSSC) is a third-generation photovoltaic device that holds great promise for the economic conversion of solar energy into electrical energy. TiO2 layers have been deposited by the spin-coating technique based on excess of a TiO2 solution on glass substrates heated to a fixed temperature of 80°C. The objective of the present study is the study of the effect of dye on the optical properties of these layers. For this, we used UV-Visible spectroscopy for optical characterizations. UV-Visible transmission spectra confirm that it is possible to obtain good transparent TiO2 films with a 68 to 87 % transmittance in the visible. The maximum absorption of anthocyanin changes in the visible range when the pH of the solution varies between 3 and 12.
