An Increase in Conversion Efficiency of Dye-Sensitized Solar Cells using Bamboo-Type TiO2 Nanotube Arrays

- Oriented bamboo-type TiO2 NT arrays were prepared by AV anodization of Ti for DSSCs.
- Increased dye loading in inner & outer walls due to bamboo structure were estimated.
- Electron transfer time of TiO2 NT arrays was unaffected by the bamboo structure.
- Cell efficiency of 7.36% was achieved due to higher dye loading.
