Summary, etc. TiO<sub>2</sub>-Ag nanocomposites have been prepared by hydrothermal process for the preparation of photoelectrode for dye-sensitized solar cells. The formation of TiO<sub>2</sub>-Ag nanocomposites have been confirmed by the transmission electron microscopy (TEM), UV-Vis spectroscopy, X-ray diffraction and energy dispersive X-ray analysis. The TEM images confirm that silver nanoparticles of average size 30 nm are dispersed inside the TiO<sub>2</sub> matrix. Electrophoretic deposition technique (EPD) is successfully utilized to incorporate TiO<sub>2</sub>-Ag nanocomposites in commercially available TiO<sub>2</sub> nanoparticle to prepare photoelectrode on transparent oxide substrate. Incorporation of TiO<sub>2</sub>-Ag nanocomposites by EPD technique has been done in different ways: in all the layers of TiO<sub>2 </sub>photoelectrode and in only the top layer of TiO<sub>2 </sub> photoelectrode. X-ray diffraction, field effect scanning electron microscopy in back scattered mode and photoluminescence (PL) spectroscopy study confirm the presence of TiO<sub>2</sub>-Ag nanostructure in prepared photoelectrode. The current-voltage characteristic shows 78% and 67% enhancement of photocurrent and power conversion efficiency (PCE) respectively in the DSSC with Ag incorporated photoelectrode compared to the cell without Ag nanoparticles and maximum PCE obtained in DSSC with TiO<sub>2</sub>-Ag is 7.5%.
