According to Solar Junction, the company has set a world record for energy efficiency for a commercial ready production solar cell. The company says the power conversion efficiency of its photovoltaic cells was measured at 44 percent at 947 suns, surpassing their own record of 43.5 percent at 418 suns set in April 2011. Both records were verified by the National Renewable Energy Laboratory (NREL).

“Breaking our own world record cements Solar Junction as an innovator and leader in the multi-junction cell space,” said Vijit Sabnis, VP Technology at Solar Junction. “We continue to push technological boundaries to further drive CPV costs down.”

The company has developed A-SLAM materials that provide CPV system manufacturers the ability to deliver efficience conversion of solar to electrical energy. CPV panels work by concentrating sunlight onto multi-junction cells that are manufactured at Solar Junction’s San Jose, California facility.

Soon Solar Junction will commission a 6″ production fabrication facility that was funded partially through a U.S. Department of Energy SUNPATH contract. Shipments are expected to begin in early 2013.
