Description

The rapid growth of global energy consumption demands a long-term sustainable solution. Research over the past several decades has been focused on meeting this demand with solar production of hydrogen fuel via a process called photoelectrochemical water splitting. Recently, much of the focus has been on bismuth vanadate (BiVO4), which has been shown to improve solar-to-hydrogen conversion efficiency and to be stable against corrosion. Efforts at UW-Stevens Point have successfully deposited a BiVO4 film on a fluorine-doped tin oxide electrode. Attempts to synthesize a similar film on a GaInP2 electrode are ongoing. Future efforts will explore alternative deposition methods and intermediary layers to increase adhesion between the BiVO4 and GaInP2 layers of the electrode.
