Great news. I hope they get these things out to market soon. The sooner, the better. I hope to see them also come out with small PV panels for individuals as quickly as possible.

A word on risk management Those metals are not without drawbacks from a sustainability standpoint: life cycle toxicity questions need to be tackled before exposures scale up. Secondly, design life likely hinges on the polymer. Whereas the typical design life is 25 - 30 years+ for todays' rigid solar panels, these new thin films might be an order of magnitude lower unless the base film is a flouropolymer, from which another layer of issues is introduced.

I wish them all the success in the world, but I remain skeptical for the moment. Their history of incredible claims combined with nothing but hype to back them up has me thinking Segway.

I've been watching Nanosolar for a while, and I still havn't been able to find information on solar cell efficiency or cell lifetimes. I've gotten a bit jaded about companies pitching the "next big thing" that don't put up hard numbers.

Regarding the polymer lifetime issue: Maybe I just didn't find it, but I do not see where Nanosolar has said they're printing onto a polymer. As far as I can tell, they are not revealing the substrate material. Flexible substrates do not have to be plastics, so maybe they have something more durable.

Mike, I remember reading somewhere that Nanosolar is about 10-12% efficient (compared with 14-15% for regular Silicon cell and around 30-35% for triple junction cells manufactured by SpectroLabs).
According to Wikipedia Nanosolar cells will cost between 1/10th and 1/5th the industry standard per kilowatt. Though you would need larger square footage to generate the same amount of electricity.
Another fact that Justin failed to point out was the 430 MW is a HUGE capacity, unprecedented in the industry.
Also, this "news" is well over two months old.
