Facile preparation of titanium dioxide nano-capsule arrays used as photo-anode for dye sensitized solar cells

- TiO2 nanoparticles have been introduced into TiO2 nanotube using a facile liquid phase deposition method at low temperature in atmosphere.
- Dye solar cells have been assembled on flexible titanium substrate.
- The incident photo-electron conversion efficiency has been improved 76% compared with pure TiO2 nanotube arrays.
