Abstract :

The rare-earth elements, Gadolinium and Samarium, are doped with TiO2 by hydro thermal synthesis technique. The obtained materials underwent the characterizations of XRD, HRTEM, UV-Vis Spectroscopy and XPS. DSSCs were fabricated using N719 dye, redox electrolyte and Platinum as counter electrode. The efficiencies of DSSCs depend on the electron transport within the TiO2-dye-electrolyte system. After the fabrication and simulation, among the two, Gd3+ doped TiO2 gives the desired outcomes and higher efficiency than the pure and Sm3+ doped TiO2. Thus it proves to be a superior solar cell anode material.
