In this work we have prepared Ag doped TiO₂ composite
semiconductor by microwave hydrothermal methods. The prepared TiO₂/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 TiO₂/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%.
