Co-Sensitization Promoted Light Harvesting Capability of Dye-Sensitized Solar Cell (DSSC) Using Anthocyanin-Based Dye


Article Preview

High efficiency of light-to-energy conversion in dye-sensitized solar cell (DSSC) was achieved by applying anthocyanin as photosensitizer and TiO2 as photoelectrode. TiO2 anatase phase was synthesized by using co-precipitation method from TiCl3 precipitate. Anthocyanin (A) from Garcinia mangostana pericarp was combined with β-carotene (B) from Daucus carota and curcumin (C) pigments from Curcuma longa. According to UV-Vis analysis the wavelength absorptions of anthocyanin, β-carotene, and curcumin are 399 nm, 471 nm, and 470 nm, respectively. The A–B–C produced the short-circuit current density (JSC) of 77.7 μA, the open-circuit voltage (VOC) of 343.2 mV, the fill factor (FF) of 32.3, and the efficiency (η) of 0.042%. It is found that there exists a synergistic effect between anthocyanin and curcumin as indicated by broader absorption wavelengths, whilst the mixture between anthocyanin and β-carotene does not show the synergistic effect. The high efficiency of layered co-sensitization is attributed to the high adsorption capacities of curcumin in the outer layer. On the other hand, the effect can be explained on the basis of light scattering effect.
