Abstract :In this work we have prepared Ag doped TiO 2 composite semiconductor by microwave hydrothermal methods. The prepared TiO 2 /Ag photoanode was characterized via XRD, FE-SEM and DRS spectroscopy techniques. Then this composite was used as a photoanode material for dye sensitized solar cells. The TiO 2 /Ag photoanode was prepared by spin coating technique. The sensitizer of this solar cell is indigo carmine and it was prepared in different pH solution in ACN. The higher solar cell efficiency values were achieved up to 1.91% with TiO2/Ag photoanode and in pH 5.3 indigo carmine dye solution. As a result, in this study, it was observed that the addition of Ag nanoparticles was increased the efficiency of solar cell by 20-45%.Keywords : Dye sensitized solar cells, indigo carmine, Ag/TiO2
