Abstract

Thin film semiconductors are a desirable option for photoelectrochemical (PEC) hydrogen production due to potential low-cost and large-area fabrication possibilities. CuInSe₂ and related thin films have been thoroughly studied for application as solar energy conversion devices yielding high photovoltaic (PV) efficiencies. CuGaSe₂ is a semiconductor thin film in this family with a band gap of 1.7 ev, the minimum band gap for a PEC water splitting system. CGS is examined as a top layer absorber on a Si PV junction in a tandem monolithic PEC device. These materials are compared to individual CGS absorbers to examine the potential of an ideal tandem system using CGS. While CGS alone has band edges too negative, the valence band position of the tandem cell is positive of the water oxidation potential at most pH, indicating potential water splitting capabilities. This is an abstract of a paper presented at the 231st ACS National Meeting (Atlanta, GA 3/26-30/2006).
