Solar power is a rapidly developing area of research due to the need for alternative energy sources.  Recent research reported construction of a photovoltaic cell with a potassium iron(III) hexacyanoferrate(II) cathode and a titanium nitride photo-anode.  This photo-anode actually relies on the formation of photo-active byproducts titanium oxynitride and titanium oxide which form during the deposition.  The uncertainty of how much byproduct forms leads to uncertainty in performance of the photocell.  By changing the photo-anode material to bismuth vanadate, the performance of the photovoltaic cell could be improved because the photoactive species does not rely on the formation of photoactive byproducts.  A photovoltaic cell was fabricated using bismuth vanadate as the photo-anode.  Electrochemical analysis was performed to determine the efficiency of the cell.
