The performance of nanostructured metal oxides (ZnO and TiO2) based dye sensitized solar cells (DSSC) were investigated. Natural dye, chlorophyll extracted from fresh spinach leaves, was used as sensitizer for fabrication of the cells. ZnO was synthesized by chemical bath deposition technique. The Field emission scanning electron microscopic (FESEM) images show hexagonal patterned ZnO nano-towers of 5 mu m length and similar to 1 mu m diameter. TiO2 was synthesized by sol-gel method. The FESEM images show that the TiO2 nano-rods of 2 mu m length and similar to 300 nm diameter. TiO2 based DSSC was possessed better efficiency of 0.27% as compare to ZnO based DSSC of 0.13%.
