Research Interests
My group develops high efficiency photovoltaics for solar energy. We have three main thrusts: 1.) upconversion of wasted infrared light to high-energy electrons, 2.) new combinations of epitaxial semiconductors to provide increased efficiency in conversion of the full solar spectrum to electrical energy, and 3.) lower cost growth of high efficiency solar cells on silicon wafers. We also work to create CMOS-compatible lasers for low energy, high bandwidth optical interconnects in multicore processors and exabyte data centers and on steep subthreshold FETs for low energy consumption.
