Chemistry

Our research involves the development of new inorganic materials suitable for application in various energy conversion schemes from solar photoelectrochemical water splitting to generate hydrogen, regenerative photoelectrochemical solar energy conversion, and light emission in electroluminescent devices.

Composite photoelectrodes for solar fuels: Interfacing light-harvesting oxide photoanodes with water-oxidation electrocatalysts improves solar-to-hydrogen conversion in photoelectrochemical cells.

The high surface areas of Fe2O3 photoanodes are used to trap photogenerated holes. Hole transfer to a catalyst is facilitated by its conformal deposition onto this mesostructure. We are developing high-gain luminescent solar concentrators based on doped semiconductor nanocrystals embedded in optical waveguides. These devices serve as antennae for collecting, concentrating, and re-purposing solar photons. We are improving the performance of solar-fuels-generating photoelectrodes by interfacing them with redox catalysts and studying the properties of the new semiconductor/catalyst interfaces.
