Nanosolar Increases Solar Cell Efficiency to 16.4% and Starts Mass Production

makes an interesting point about the true gains in efficiency. The second press release:

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."

Correction: The 16.4% figure above is for the best Nanosolar solar cells, not for all of them. The company states that: "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." That's still very good, but far from 16.4%. Sorry for the confusion.
