Abstract

We demonstrate that TiO₂ nanotube arrays (TNTAs) prepared by template-assisted atomic layer deposition (ALD) has successfully yielded vertically standing, highly ordered, and dimension and morphology controllable TNTAs on substrates. The prepared TNTAs are ideal photoanode structures in solid-state dye sensitized solar cells (DSSCs) for enhanced solar energy conversion efficiency.
