Siva Power CIGS cells approach 19 percent efficiency
Former NREL director Charlie Gay has joined Siva Power's CIGS PV team
Siva Power has achieved near record efficiency with its CIGS panel technology.
The firm's product has achieved nearly 19 percent efficiency in a record time of just ten months.
In addition, the company welcomes leading solar energy expert, Charlie Gay, Ph.D., to its Technical Advisory Board.
Gay joins Rommel Noufi, Ph.D., John Benner, and Markus Beck, Ph.D. to support Siva Power as it creates a profitable path to sub-$0.40 per watt solar power and unprecedented production scale.
Siva Power repositioned itself for success in February 2013 by transitioning to CIGS thin-film technology. In December 2013, the National Renewable Energy Laboratory (NREL) certified Siva Power as achieving a laboratory efficiency of 18.8 percent - less than a year after the company shifted its technology focus.
In achieving 18.8 percent efficiency, Siva Power has nearly equalled accredited international research institutes such as NREL, the Swiss Federal Laboratory for Materials Science and Technology (EMPA) and ZSW Centre for Solar Energy and Hydrogen Research, all of which have engaged in research and development (R&D) on CIGS for upwards of 20 years.
Siva Power also surpasses the majority of solar companies using CIGS technology, many of which have taken more than five years to achieve this degree of panel efficiency. Much of this success is directly attributable to the deposition approach that Siva Power has selected.
All CIGS efficiency records over the past two decades have been achieved using three-stage co-evaporation. This is the method that Siva Power has elected to scale to high-volume manufacturing.
"The Siva Power team's rate of progress in demonstrating these high efficiencies is unprecedented and is further proof that our technology, combined with an unrivaled manufacturing plan, is the most viable pathway to a profitable and sustainable solar industry," says Brad Mattson, Siva Power CEO. "This efficiency milestone speaks to our team's expertise, and we welcome Charlie's knowledge and experience as a critical component toward helping us achieve even more."
With more than 30 years of solar industry experience,. Gay is an internationally recognised pioneer in photovoltaics (PV). In 2013, Gay was elected to the U.S. National Academy of Engineering, one of the highest professional honours accorded engineers. At present, Gay is co-founder and president of Greenstar Foundation, an organisation dedicated to enabling microenterprise development in rural communities.
Gay began the early part of his career working for ARCO Solar where he forged the transition of single crystalline silicon from R&D to mass production. In 1994, he was elected director of NREL where he managed an annual budget of more than $235 million, with a staff of more than 1,000 employees. After his tenure at NREL, he served as president of ASE Americas.
From 2001 to 2005, Gay served as chairman of the SunPower Advisory Board. He then joined Applied Materials in 2006 as corporate vice president and general manager of the Solar Business Group. He was named president of Applied Solar and chairman of the Applied Solar Council in 2009.
"I am honoured to join such an experienced team with Beck, Noufi, and Benner," says Gay. "Collectively, they represent one of the most experienced groups ever assembled for CIGS technology and high volume manufacturing."
