This work reports the infusion effect of Mg into TiO₂ nanocomposite for DSSC photo-anode application. TiO₂-MgO Porous nanosized structure oxide film was obtained using sol-gel technique at 400⁰C. The fabricated film is described in terms of crystallinity and morphology by XRD and HR-SEM. The fabricated thin-film demonstrated the structure of a semi-crystalline (Ti₂.₉₄Mg 0.06 O5) and Ti₉O₁₇ nanoparticle. SEM exhibited a smooth surface with crystalline nature, which matched with the crystallites size that estimated from XRD analysis and can be utilized as the large efficiency of the solar cells. The optical spectra showed that porous nanosized 70TiO₂-30MgO film band gap is 2.5 eV. XRD and optical results suggested that the insert of MgO in TiO₂ film compellingly improved the TiO₂ anode thin films.
