The US Department of Energy's National Renewable Energy Laboratory has officially certified an aperture efficiency of 17.1% for a solar cell fabricated using Nanosolar's non-vacuum, flexible foil technology. The tests were carried out on September 1 under standard test conditions of 1000W/m2 at 25°C.

“This achievement demonstrates that a non-vacuum CIGS deposition process can deliver world-class efficiency,” said Nanosolar CEO Geoff Tate. “At the same time, Nanosolar's unique roll-to-roll printing process delivers substantial manufacturing cost benefits.”
