The second press release: http://www.nanosolar.com/company/blog/nrel-certifies-164-nanosolar-foil-efficiency http://www.nanosolar.com/company/blog/nrel-certifies-164-nan... states: "In terms of our current baseline production process, our best production rolls now achieve higher than 11% median efficiency measured as equivalent to panel efficiency, with very tight cross- and down-web uniformity."
