Research Activity per Year


Personal Profile

In 1997, Andrew Norman joined NREL as a senior research associate to study lateral modulations in III-V semiconductor short-period strained layer superlattices and atomic ordering in III-V alloys, and established collaborations with the NREL's III-V team to study materials issues in III-V and other novel semiconductor alloys of interest for multi-junction solar cells. He became a permanent employee at NREL in 2000. Since then he has pursued research into a wide range of topics, including quantum dot solar cells, III-V metamorphic multi-junction solar cells, molecular-based upconversion, novel epitaxial relationships, and more recently, epitaxial growth of CZTS, and the fabrication of high efficiency single crystal Si and Si-based tandem cells. 

Research Interests

Norman's research interests include epitaxial growth including novel epitaxial relationships, atomic ordering, phase separation, and defect formation etc.; transmission and scanning transmission electron microscopy of materials; epitaxially grown quantum dots and wires; next generation photovoltaic devices; multi-junction solar cells; solid-state lighting; low-cost, large-area fabrication routes for semiconductor devices.
