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 µm length and ~ 1 µm diameter. TiO 2 was synthesized by sol-gel method.The FESEM images show that the TiO 2 nano-rods of 2 µm length and ~ 300 nm diameter.TiO 2 based DSSC was possessed better efficiency of 0.27% as compare to ZnO based DSSC of 0.13%. ©2019 Elsevier Ltd.

Introduction Dye sensitized solar cell (DSSC) is a newly developed solar cell that works similar to photosynthesis process where different dye sensitizers are used for absorption of light energy. A DSSC is composed of a dye sensitizer attached * Corresponding author. Tel.: +91-9647361722 E-mail address: dola.sinha@gmail.com
