Hillhouse’s research lies at the nexus of nanomaterials and energy conversion. Within the realm of molecular and nanoscale science many new molecules, nanocrystals, electronic materials, and device architectures can be envisioned that may be able to address our current energy harvesting, utilization, and storage challenges. However, the scientific understanding of the chemistry and fundamental processes involved and the engineering necessary to develop economic and sustainable solutions is still in its infancy. Research efforts within the group span the range from fundamental studies of molecular precursor chemistry, nanocrystal nucleation and growth, and materials defect chemistry to device fabrication, characterization, and modeling of solar cells and fuel cells to system-level analyses of the life-cycle and impact of potential new technologies. This system-level approach is used to identify opportunities, avoid unforeseen consequences (like indirect market effects and environmental issues), and enlighten the molecular and nanoscale approaches we develop.
