| Research Abstract |
Anthocyanins are natural plant pigments showing wide range of colors from red through purple to blue. Because of the unique characters and high molar absorptivity, anthocyanins are expected as coloring materials of the dye-sensitized solar cells (DSC). However, the DSC studies of anthocyanins are limited due to the difficulties of purification. In this research, various natural and synthetic anthocyanins and flavonols were prepared and the photoelectric conversion-efficiency was measured. TiO2 electrode was immersed into the solution of the pigments in water or methanol, then the electrode was composed according to the previous reported general procedure. The power conversion efficiency (AM 1.5, 100 mWcm-2) of the pigments were 0.2%-0.6%. Estimated HOMO-LUMO energy level of the pigments indicated the reason of low electro-conversion yields. Form the results we could obtained the strategy of molecular design to increase photoelectric conversion-efficiency.
