Research Interests

  • Solar Energy Conversion (CIGS and CZTS solar cells, device architecture, simulation)
  • Nanomaterials (nanocrystals, nanowires, quantum size effects)
  • Colloidal & Interfacial Phenomena (self-assembly, nucleation & growth)
  • Electrochemistry (semiconductor electrochemistry, fuel cells, batteries)
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.

Graduate and Postdoctoral Researchers

The Hillhouse Group typically has openings for new students and postdocs. Please check for openings here.

Undergraduate Researchers

There are openings for two to three undergraduate researchers every year. Self-motivated University of Washington undergraduate students in Chemical Engineering, Electrical Engineering, Materials Science & Engineering, Chemistry, or Physics should contact Prof. Hillhouse by email and send their resume or CV. There is a two quarter minimum, but the depth and impact of the experience will increase with the length of time in residence. Many undergraduate students stay in the group for a year or more and do research over the summer and even after graduation.


Hillhouse has developed and taught graduate courses on: (1) Advanced Solar Energy Conversion, (2) Electrochemistry, (3) X-ray and Neutron Scattering Methods, (4) Nanomaterials Chemistry and Engineering, and (5) Transport Phenomena. He has also developed an undergraduate course on the Principles of Molecular Engineering which is offered every year. He has been recognized for his teaching and received the Shreve Award for Excellence in Undergraduate Teaching from Purdue University.
