Fabrication of Titanium Dioxide Nanotubes Array For Photoanode in Mesoscopic Solar Cells
- One dimensional (1D) nanostructures have been attracting the research interest and have many potential applications including mesoscopic solar cells. In this work, 1D titanium dioxide (TiO2) nanotubes array have been fabricated by the electrochemical anodization of Ti foils in electrolyte. Focus was placed on the morphology and size control of TiO2 nanotubes by varying fluoride content in electrolyte (0.3-0.6 Wt%). Fluoride contents of 0.4 and 0.5 Wt% are optimum for production of well-defined nanotubes array with uniform size distribution (tube diameter of 100 - 140 nm). It is also observed that higher the fluoride concentration, the larger is the anodization current across the sample. The tube morphology and size are strongly sensitive to the fluoride content in electrolyte.
