A modified sol-gel method for preparing nanostructured Nb-doped TiO 2 DSSC photoanode
Nb-doped TiO 2 thin films have been successfully prepared using liquid phase solution method. For the first time, Nb-doped sol-gel has been combined with commercially available TiO 2 nanopowder (Degussa P25) for preparing Nb-doped TiO 2 photoanode for DSSC application. EDX analysis confirms the pres...

| Summary: | Nb-doped TiO 2 thin films have been successfully prepared using liquid phase solution method. For the first time, Nb-doped sol-gel has been combined with commercially available TiO 2 nanopowder (Degussa P25) for preparing Nb-doped TiO 2 photoanode for DSSC application. EDX analysis confirms the presence of Nb in the thin films. Nb-doped TiO 2 sample showed improvement in term of electrical resistivity characteristic compared to undoped sample with 8.0 at% Nb-doped sample having the lowest resistivity value. When utilized as photoanode in DSSC, the energy conversion efficiency showed an improvement of 81.3% compared to the undoped one. © 2012 IEEE. |
