This research develops low-cost gallium arsenide solar-cell manufacturing to accelerate global decarbonization. Gallium arsenide absorbs light far more efficiently than silicon, potentially enabling cheaper and less capital-intensive solar production. By improving scalable manufacturing methods, the work aims to reduce the cost of expanding renewable-energy infrastructure needed to combat climate change.

This research investigates how electrolyte chemistry influences battery performance through the formation of the solid electrolyte interface (SEI). By developing fluoride-rich electrolytes for lithium metal batteries, the work improves battery stability and efficiency, advancing renewable energy storage, electric transportation, chemical manufacturing, and future energy technologies beyond conventional lithium-ion systems.

Silicon carbide is strong and heat-resistant but fails catastrophically due to low fracture toughness. By adding graphene, cracks are deflected and require more energy to propagate. This research has doubled fracture toughness, enabling potential use in nuclear reactors and other high-temperature structural applications.

Rising global electricity demand requires materials that conduct efficiently at extreme temperatures. This research develops scalable metal–ceramic composite conductors with tunable electrical properties by controlling particle interfaces and packing. These materials overcome limitations of metals and semiconductors, enabling efficient, affordable energy technologies for high-temperature industrial applications.
