Wahid Shams-Kolahi (Persian: وحید شمس کلاهی) is a scientist and an electrical engineer who is known for his research in photovoltaic-related technologies.
Dr. Shams-Kolahi was born in
Arak, Iran, in 1965. He obtained his undergraduate degree in electrical engineering at
University of Stuttgart and joined the graduate school of electrical engineering/electrophysics, led by Professor
Werner H. Bloss.[1] He worked under Professor Bloss with the Institute of Physical Electronics, IPE,[2] and later joined the Hamakawa Lab[3] of the Graduate School of Electrical Engineering, Faculty of Engineering Science,
Osaka University, Japan, where he obtained his master's degree in 1994 and his Ph.D. in 1997.
While at Hamakawa Lab, Wahid Shams-Kolahi conducted research on space-made materials and their potential for applications such as the absorption layer of solar cells. The team at Hamakawa Lab led by Shams-Kolahi was chosen by the
Spacelab Mission Endeavour project, a cooperation between
NASA of the United States and the Japanese
NASDA, to study the electrical and optical properties of SiAsTe amorphous- or chalcogenide semiconductors fabricated under microgravity in space as part of Endeavour mission
STS-47.
