Solar Fuels by Photoelectrochemistry:
Direct Conversion of Sunlight to Fuels

Solar energy harvested by semiconductor absorbers can be used to drive electrochemical reactions at surfaces to generate fuels such as hydrogen from water. Research in this area of the group focuses both on band gap optimization for new semiconductor syntheses as well as tailored engineering of material properties to improve efficiency. Strategies employed include nanostructuring to increase absorption, surface modification to improve stability, addition of co-catalysts to accelerate surface reactions, and incorporation into devices.
