Abstract
Nanostructured films including a plurality of nanowells, the nanowells having a pore at the top surface of the film, the pore defining a channel that extends downwardly towards the bottom surface of the film are provided. Also provided are methods including exposing a growth substrate to an anodizing bath, applying ultrasonic vibrations to the anodizing bath, and generating a current through the anodizing bath to form the nanostructured film. The nanostructured films may be formed from TiO2 and may be used to provide solid state dye sensitized solar cells having high conversion efficiencies.
