Photovoltaic Performance of Dye-Sensitized Solar Cell (DSSC) Fabricated by Silver Nanoclusters-Decorated TiO2 Electrode via Photochemical Reduction Technique
In this investigation, Ag@TiO2 nanocomposite was prepared by deposition of silver nanoclusters onto commercial TiO2 nanoparticles (known as P25 TiO2) via photodeposition technique as clean and simple photochemical route. The synthesized Ag@TiO2 nanocomposite was utilized in the fabrication of dye-se...
