NREL Partnering with GreenVolts to Commercialize IMM Solar Cell
March 31, 2009
NREL is partnering with GreenVolts to commercialize the Inverted Metamorphic (IMM) advanced multi-junction solar cell design. Through its Technology Commercialization and Deployment Fund, the U.S. Department of Energy has committed $500,000 for GreenVolts to co-develop NREL's patents and bring this new technology to market.
"We believe this new IMM technology is key to a tremendous leap forward in solar cell efficiency," said NREL Director Dan Arvizu. "We are pleased to be working with GreenVolts to both refine these advancements and provide for a viable way to bring them to market."
Throughout a two-year cooperative research and development agreement, NREL will provide necessary technology specifications and process information, as well as advice and assistance in the device optimization and technology transfer. NREL will also provide test and measurement services to qualify the results of the transfer process, including its reliability. GreenVolts plans to develop a customized cell tailored to its optical system, accelerating the widespread commercialization of the technology through its high-volume manufacturing partners.
The NREL IMM technology has demonstrated one of the world's highest reported solar cell efficiencies at 40.8%, and holds the promise for even further substantial increases. A customized solar cell will help GreenVolts optimize its concentrating photovoltaic system by increasing efficiency and reliability while reducing the overall cost of energy.
