Adele Tamboli has a joint appointment at NREL and Colorado School of Mines. Her research focuses on semiconductor materials science and device physics for renewable energy and energy efficiency, including silicon-based tandem solar cells, novel epitaxial and thin-film solar absorber materials, and novel materials for light-emitting diodes. Dr. Tamboli is in the Materials Physics research group in the Materials Science Center. Her projects include:

  • Mechanically stacked III-V/Si tandem solar cells built using transparent, conductive adhesives, including three-terminal tandem solar cell designs
  • Developing the II-IV-V2 class of semiconductors (e.g. ZnGeP2, ZnGeN2, MgSnN2) and understanding the impact of cation disorder in these materials, which may be used to tune material properties at a fixed composition
  • Developing III-N/ZnGeN2 green light emitting diodes
  • NREL's Hands-On Photovoltaic Experience (HOPE), a summer workshop for graduate students in photovoltaics
