Kirstin Alberi

Center Director I-Technical


Kirstin Alberi is the center director of the Materials Science Center in the Materials, Chemical and Computational Science directorate. 

She received a doctorate in materials science and engineering from the University of California, Berkeley in 2008, where she studied the optical and electronic properties of highly mismatched semiconductor alloys. She came to NREL as a postdoctoral researcher in the Silicon Materials and Devices group to investigate the design and performance of thin crystalline silicon (c-Si) solar cells fabricated on inexpensive substrates. In 2010, Kirstin joined the Materials Physics group to conduct basic research on the optical and electronic properties of semiconductor alloys for photovoltaic, solid-state lighting and other energy-relevant technologies.
