| Abstract: | Nanoporous titanium dioxide(TiO2)films was prepared by sol gel method. For the first time, a novel device based on conventional dye sensitized ultraviolet electric cell was obtained by using anthocyanins and coumarin as the dye and Fe(CN)6]3-/Fe(CN)6]4- as electrolytes. The I-V characteristic of the cell, which had 0.36 mV as its maximum voltage and 0.02 μA/cm2 as its maximum current were described. The mechanism of photoemission was also investigated. |
