Location: Whittemore 654 (6th Floor Conference Room)

Abstract:

An optimization is done on the fill factor of an MBE-grown p-on-n GaSb photovoltaic by reducing the series resistance brought on by the layout of the front metal electrodes while simultaneously minimizing their coverage area. The optimization indicates a variation in the substrate carrier lifetime.

Bio:

Daniel Herrera received a B.S. degree in Electrical Engineering from the University of New Mexico in 2013. He is currently a second year Ph.D student working in Dr. Luke Lester's research group. His current research project with Dr. Lester is a continuation of research done at the Center for High Technology Materials at UNM, which consists of fabricating and characterizing GaSb-based TPVs. Additionally, he has done research in thin-film optical coatings, high-effiency quad-junction space solar cells, and surface plasmon resonance-enhanced PV cells.
