Robust and inexpensive photoelectrodes for solar water splitting tandem cells

Prof. Kevin Sivula
École polytechnique fédérale de Lausanne

A device that can convert solar energy into a chemical fuel with good efficiency while also offering high stability and the capability to be constructed with widely available materials using inexpensive processing techniques is urgently needed. A practical and inexpensive device could be constructed with an n-type photoanode in tandem with a p-type photocathode. In this presentation I will present our progress in the development of solution-processed photoelectrodes and their application toward overall photoelectrochemical water splitting tandem cells. Specifically, progress with a promising photoanode material, Fe2O3, and its application in a photoanode/dye sensitized solar cell tandem device will be described. In addition, I will present progress towards the realization of stable and highly active photocathode materials based on copper and their application in water splitting cells.
