Ken Zweibel has almost 30 years experience in solar photovoltaics. He was at the National Renewable Energy Laboratory (Golden, CO) much of that time and the program leader for the Thin Film PV Partnership Program until 2006. The Thin Film Partnership worked with most US participants in thin film PV (companies, universities, scientists) and is often credited with being important to the success of thin film PV in the US. Corporate participants in the Partnership included First Solar, UniSolar, Global Solar, Shell Solar, BP Solar, and numerous others.
Zweibel subsequently cofounded and became President of a thin film CdTe PV start-up, PrimeStar Solar, a majority share of which was purchased by General Electric. Zweibel became the founding Director of The George Washington University Solar Institute at its formation in 2008.
Zweibel is frequently published and known worldwide in solar energy. He has written two books on PV and co-authored a Scientific American article (January 2008) on solar energy as a solution to climate change and energy problems.
