| Popis: | NH4F with ethylene glycol solution as the electrolyte, the anodic oxidation of titanium mesh surface in preparation of ordered TiO2 nanotube array. The structure, morphology and absorption properties of samples were characterized by XRD, SEM and UV spectrophotometer. The results show that, in a certain time range, nanotube length and diameter will increase with the increase of oxidation time. The best oxidation time is 60min. Ultraviolet visible spectrophotometer results show that, the optical band gap of samples is from 3.26-3.42eV. The photoelectric conversion characteristics of dye sensitized solar cell assembled with prepared nanotube arrays were tested. |
