Alumina Template Assistance in Titania Nanotubes Dye-Sensitized Solar Cell (TiO₂ NT-DSSC) Device Fabrication

Figure 1

Schematic diagrams of DSSC anode-fabricated processing by used TiO₂ NT and Al₂O₃ templates. (a) purify Al (99.7%) through anodization forming and (b) Al₂O₃ template on the Al surface, (c) remove Al substrate by CuCl₂ + H₂O solution, (d) remove barrier layer by H₃PO₄ solution, (e) sputter TiO₂ as under layer and ITO as conducted layer forming conductor electrode, (f) deposit TiO₂ inside Al₂O₃ template by TiF₄ solution to form DSSC anode.
