Photoelectrochemical Hydrogen Production

In this project, the team at HNEI engineered advanced thin film semiconductors for solar-powered hydrogen production. In this process, a thin film solar absorber immersed into an aqueous solution uses sunlight energy to split water into hydrogen and oxygen. Such process requires materials with specific optical and electrochemical properties in order to generate hydrogen efficiently and durably. Three important material classes with high potential for solar-powered water splitting were investigated in this project: metal oxides, chalcopyrites and amorphous silicon carbides.
