Joe Roy-Mayhew, Chemical and Biological Engineering

Joe’s research combines material synthesis and processing with electrochemical characterization to study the use of functionalized graphene sheets (FGSs) in dye sensitized solar cells. By incorporating FGSs, atomically thin, wrinkled sheets of carbon with exceptional electrical and mechanical properties, he strives to increase the efficiency and reduce the costs of solar cells.

He is looking to make porous, highly conductive electrodes with large surface areas by understanding how the sheets pack together and form networks. He is interested in using these electrodes as a catalytic counter electrode (to replace platinum), and as a 3-D conductive scaffold at the working electrode (to reduce resistances in the solar cell).
