Dye-Sensitized Solar Cells by Fruits

Dye-sensitized solar cell is a promising technology that converts sunlight into electricity, with broad potential in contributing significantly to solve the future energy problem that humans are facing. The use of natural pigments as sensitizing dye for the conversion of solar energy in electricity enhances the economical aspect, as well as is beneficial from the environmental point of view. Dye-sensitized solar cells (DSCC) were assembled by using natural dye by using two different fruit which contain anthocyanine dye: red grapes and orange. The performance of DSCC is based on natural dyes extracted from fruits. The extracts were characterized using ultraviolet-voltage and typical current-voltage curves were obtained for the cells. The best performance was obtained from red grapes.
