Renewable Energy and Energy Efficiency
2012 Fulbright S&T Fellow

Jephias Gwamuri is a doctoral student in the Material Science and Engineering at Michigan Tech. His Ph.D. research is aimed at exploiting plasmonics and photonics to design and fabricate plasmonic - metamaterial based solar cells. In his project he is exploring to what extent it is possible to manage the solar radiation efficiently using plasmonic metamaterial perfect absorbers integrated in hydrogenated amorphous silicon (a-Si:H)-based solar photovoltaic devices. This knowledge will contribute to increasing the efficiency and lowering the cost of production of solar cells. His project will also include PV system designing and optimization.

Jephias Gwamuri received his first degree from Cuba in Physics and Electronics. He completed his master’s in Lasers and Applied at the National University of Science and Technology (NUST) during which time he went to University of Cape Coast, Ghana as an International Centre for Theoretical Physics (ICTP) research fellow. He then joined the department of Applied physics NUST as a faculty member in 2005. Jephias coordinated a number of projects including the International Atomic Energy Agency (IAEA) funded RAF-8040 Zimbabwe project and the Regional Environmental Initiative Network (REIN) – Africa funded Biofuels Project. He has co-authored several research articles, technical reports, a policy brief and a contribution to a book chapter. Mr. Gwamuri has received some awards towards his research work including the ICTP-African LAM network award and the researcher of the year award at NUST 2011. He joined Professor Joshua Pearce's Michigan Tech's Open Sustainability Technology [MOST] Research Group in August 2012. Jephias is currently the group specialist in thin film characterization using the Variable Angle Spectroscopy Ellipsometry (VASE) and the X-ray Diffraction (XRD) techniques.
