Synthesis of Mesoporous Anatase TiO2 Nanotubes as a Working Electrode for Solid-state Dye-sensitized Solar Cells |
| 초록 |
Mesoporous anatase TiO2 nanotubes (NTs) with the diameter of about 7~12 nm and the length of several hundred nanometers were synthesized by a hydrothermal method on commercial TiO2 particles in NaOH followed by HCl washing. The hydrothermal treatment temperature at 130oC was shown to affect not only the extent of particle-to-sheet conversion, and thus the resulting structures of the NTs, but also the anatase-to-rutile transformation. The surface area of the NTs was ~200 m2g-1. This value was much higher in comparison to TiO2 nanoparticles of ~50 m2 g-1. It was also found that the NT photoelectrodes had a pronounced impact on the performance of solar cells as compared to nanoparticle ones. |
