Welcome to the PEC Interface and Materials Lab!

Hu lab focuses on interfacial electrochemistry for applications in light energy to chemicals conversion. We conduct basic studies to understand and manipulate charge dynamics and charge-transfer processes at solid/liquid interfaces. We also build various solar-fuel devices that enable distributed, sustainable and low-cost chemical production.  We believe it is key to understanding non-equilibrium, reversible light-driven processes of chemical catalysis or materials synthesis, at a photoelectrochemical (PEC) interface.

Many applications rely on this PEC functional interface: converting sunlight, water, and air into energy-dense fuels; guiding additive materials growth or subtractive photo-corrosion; or even making the PEC interface self-repair. Therefore, we consider a light-driven PEC device as an open, living system especially with free and abundant sunlight in our macroscopic world as the energy inputs.

Our group is part of Department of the Chemical & Environmental Engineering at Yale School of Engineering and Applied Science. Our lab is located at the Energy Sciences Institute at Yale West Campus

We are interested in finding out the governing rules of running a light-driven artificial photosynthesitic system efficiently. We also build photoelectrochemical devices that simultaneously achieve energy storage and water treatment, for a clean and sustainable world!
