Nanosolar... Solar without Silicon

Nanosolar aims to make solar power as affordable as electricity produced by coal and natural gas. Its thin film technology involves “printing” a microscopic layer of solar cells onto metal sheets as thin as aluminum foil. The resulting panels are lighter, cheaper, and as efficient as traditional solar panels. Nanosolar is producing the cells at $1 per watt, or one-tenth of the cost of traditional cells.
