Nanosolar Achieves 17.1% Aperture Efficiency Through Printed CIGS Process

October 4, 2011

SAN JOSE, CA, Oct 05, 2011 -- Thin film solar printing leader Nanosolar, Inc. today announced that the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) has certified an aperture efficiency of 17.1% for a solar cell fabricated using Nanosolar's non-vacuum, low cost printing on flexible foil technology.

"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."

Nanosolar's mission is to become the lowest cost solar cell and panel manufacturer, independent of subsidies. This is possible because Nanosolar's unique thin film printing process enables significant cost savings when compared to conventional vacuum based deposition techniques. In addition, its high-throughput roll-to-roll printing method delivers a higher capital efficiency and better materials utilization. Together, these advantages can give Nanosolar a path to lower manufacturing costs than competing photovoltaic technologies.
