10% is low compared to the claim posted in another article.
I am wondering whether SunPower's claim is true or not. Any comment?
Lab numbers are :
2009 : 6.1%
April 2010 : 7.7% and they claim to target 10+%
No products until 2012, so still lab-level tech, but those numbers/trends are quite good.
Of course, they are not the only roll-roll Solar PV solution, and lifetimes/degradations are only hinted at.
