In this work, A new strategy for enhancing the efficiency of dye sensitized solar cells (DSSC) by doping foreign ion and co-doping TiO 2 / Fe and Cu (38 nm) was prepared by sol-gel method and successfully used as a photoanode for (DSSC). The samples were characterized by using X-ray diffraction (XRD) is used to calculate grain size, before and after Fe, Cu-doping and co-doping. Glass coating process with a thin layer on (Fluorine doped tin oxide) FTO glass by using doctor Blade technique .The

The best experimental results for doping and co-doping TiO 2 with additive Copper (II) nitrate Cu (NO 3) 2 as improved it was V OC =0.6 V, I SC =1.92 mA, I max =1.8 mA and V max = 0.55 V with fill factor (FF) = 0.87. Power conversion efficiency of the cell became 2.5%.
