NanoGram hopes SilFoil next big thing in solar power

On the way to $1.00 per watt?

NanoGram's "SilFoil" isn't exactly thin film technology, but it is thin and it uses much less silicon than crystalline solar cells, yet it is still as efficient.

That's right, the same efficiency with less silicon. That means cheaper solar power. In fact, NanoGram believes it can produce SilFoil for less than $1.00 per watt when the startup's plant opens in late 2009.

Thus far, NanoGram has secured almost $70 million in funding.
