Hugh W. Hillhouse

Energy Research Area: Developing nanocrystal-ink and molecular-ink based solar cells, nanowire-based devices, and novel fuel cells.

Rehnberg Chair Professor

Hillhouse’s research interests and expertise lie at the nexus of nanomaterials and energy conversion. He and his research team are currently focused on enabling the use of solar energy by developing innovative low-cost and high-efficiency solar cells. The effort is multipronged. One approach focuses on the development of new nanocrystal and molecular inks and their use to fabricate ultra low-cost solar cells. Another approach focuses on developing novel high-efficiency solar cells based on new cell architectures that utilize quantum dots or quantum wires. These latter devices have the potential to break the Shockley-Queisser limit. On both fronts, the group works with the entire solar cell fabrication process, starting with the chemistry to create high optoelectronic quality nanomaterials and then engineering each step of the process to fabricate, characterize, and model the photovoltaic devices.
