영어 초록

In this study, we demonstrate the photoelectrochromic devices composed of TiO2 and WO3 nanostructuresprepared by anodization method. The morphology and the crystal structure of anodized TiO2 nanotubes and WO3 nan-oporous layers are investigated by SEM and XRD. To fabricate a transparent photoelectrode on FTO substrate, a TiO2nanotube membrane, which has been detached from Ti substrate, is transferred to FTO substrate and annealed at 450°Cfor 1 hr. The photoelectrode of TiO2 nanotube and the counter electrode of WO3 nanoporous layer are assembled andthe inner space is filled with a liquid electrolyte containing 0.5 M LiI and 5 mM I2 as a redox mediator. The propertiesof the photoelectrochromic devices is investigated and Pt-WO3 electrode system shows better electrochromic perform-ance compared toWO3 electrode.
