Titanium oxide (TiO ) electrode has been the most commonly used photo-electrode for the dye-sensitized solar cells (DSSCs). Several research 2 groups have already reported that only TiO layer is not yet ideal for electron transfer in the absence of space charge layer and also demonstrated 2 the procedures for coating nanocrystalline semiconducting oxide films with a thin overcoat of a different semiconducting oxide with a higher conduction band energy level (E ). Zirconium oxide (ZrO ) is a

The electrodes were annealed at 450 C and then sensitized by 2 2 Rose Bengal (RB) dye. The DSSC fabricated by binary TiO -ZrO photo-electrode showed improved solar energy conversion efficiency than that 2 2 of fabricated only by pure component of TiO . 2
