BPN635: Structured Substrates for Enhancing the Water-Splitting Efficiency of Earth Abundant Materials

Here we focus on nano- and micro-structuring earth abundant materials to improve their water splitting performance, primarily by increasing the optical path length. The focus is on isolating structural effects and so we fix the material system to be titanium dioxide. In one structure we use texturized carbon nanotubes as the back contact. In another, we are planning to use micro-scale triangular grooves.
