AstroWatt Speaks About Its Ultra Thin Silicon Solar Cells: How do you continue to drive down the cost of cryst...

Since material costs, especially silicon, are the dominant cost component in panels, cost reduction becomes about lowering the amount of silicon per panel, which is currently at 6 grams per watt, give or take. Manufacturers spend a great deal of time and energy fabricating blocks of polysilicon, only to see up to half of that hard-earned material turned into sawdust in the wafer production step. Thinner silicon -- and more efficient ways of slicing silicon or fabricating silicon wafers -- are obvious paths to further lower solar module pricing. The DOE's Steve Chu has a penchant for this kind of technology. I just spoke with Curt Vass, the CEO of Austin, Texas-based AstroWatt . Vass comes to the startup with 15 years of experience at Applied Material's silicon products division. The firm is funded with $5.0 million from Austin Ventures and NEA and $1.5 million from the DOE...
