Fabrication and Analysis of ZnO Based Dye-Sensitized Solar Cell Using Natural Dye

"This paper is focused on the fabrication and study of photoelectric parameters of dye-sensitized solar cells (DSSCs) based on ZnO nano-particles, ZnO particle are coated on substrate using spin coating method. Set of naturally extracted dyes were selected and used for sensitizing ZnO based DSSC. All natural sensitizers were extracted by water and these natural sensitizers are used as Dye’s. The short circuit current density (I_sc) and V_oc were measured and fill factor are obtained for all the above sensitizers the data we get from ZnO based DSSCs are measured and analysed then the photo-electrochemical performance were compared to find out which dye has given good efficiency.
