The extract of Pomegranate (Bedana), Punica Granatum L. was used as a natural sensitizer of a wide band gap semiconductor ZnO based in Dye-sensitized solar cells (DSSC). It is one of the most promising devices for the solar energy conversion due to their low production cost and environmental friendly. ZnO nanorods were fabricated using sol-gel spin coating technique. The synthesis and performance study of ZnO nanorods based DSSC is reported in the present paper.
