5/13/15- Our website has migrated to a new location as Yale is phasing out the Academic Commons platform. Please visit us at: http://campuspress.yale.edu/leegroup

The Lee Group at Yale works at the intersection between electrical engineering and materials science. We aim to establish connections between material growth conditions, material structure at the micro- and nano-scale, optical properties, electrical properties, and device performance. Current areas of interest include:

  • Multi-junction solar cells and solar cell materials
    • Wide-bandgap solar cells for high-efficiency concentrator and space photovoltaics
    • III-V cell integration on Si for low-cost, high-efficiency photovoltaics
    • Methods and materials for hybridizing concentrating solar power (CSP) with concentrator photovoltaics (CPV)
  • Novel epitaxial self assembly techniques for nanocomposite and quantum dot formation
  • III-V on Si optoelectronic integration and other novel light emitters

In addition, we pursue a wide range of work with our amazing collaborators on topics such as: novel 2D materials, flexible optoelectronics, and quantum/classical optics. All of these are enabled by our expertise in MBE growth and materials characterization.
