Photoelectric performance of TiO2 nanotube array film of highly transparent vs nontransparent on FTO glass

This work focused on preparing the highly transparent TiO2 nanotube array(TNT) film and measuring its photoelectric performance. The highly transparent TNT film was successfully fabricated on FTO glass combining the magnetron sputtering and anodization method. By comparing the photoelectric performance of transparent TNT and non-transparent TNT films obtaining in the same method, it was observed an interesting phenomenon under visible light irradiation that the photocurrent response of transparent TNT film was higher than that of non-transparent TNT film, while the photocatalytic activity of transparent TNT film was lower than that of non-transparent TNT film.
