I work on exploratory compound semiconductor materials and devices for high speed and energy conversion. Specifically, I work on InAs and related alloys for high speed and GaP, ZnSe and GaAsZnSe for solar cells. These materials are particularly important for use as the top high band gap cell for ulta efficiency photovoltaic (PV) systems that use optical concentration. I also work on using Al rich alloys to split water into hydrogen and heat.
Impact Statement & Explanation of Research:
At present there are no practical high band (2.4 eV) materials available for the top cell. If success my solar cell projects will finally enable economically viable PV systems capable of >50% solar power to electrical power conversion efficiencies.
If my water splitting project is successful, it will enable an economically viable green technology that will effect a 10 percent reduction in fossil fuel use for all of the US energy consumption.
