Dr. Contreras, formerly a senior scientist at the National Renewable Energy Laboratory (NREL), was a key member of the team that achieved the world-record conversion efficiency of 20% with CIGS solar cells. Throughout his career with NREL, Dr. Contreras has produced several world-record energy conversion efficiencies and holds seven US patents in this field.
He has extensive experience in all facets of solar cell and PV module fabrication, both front and back end, and has worked with nearly all types of CIGS (copper-indium-gallium-diselenide) technology, manufacturers and researchers dating back to the early 1990s.
“We are very fortunate to bring Miguel into the Ascent family,” said Dr. Joseph Armstrong, CTO and founder of Ascent Solar. “The PV world is relatively small, and we have worked with Miguel for nearly three decades. He brings his expertise and world-record efficiency credentials in CIGS technology to Ascent. His most recent work, on high specific power PV solutions, is aligned well with the core technologies at ASTI.”
