Nanosolar 'prints' first flexible solar cells

Well-financed solar start-up Nanosolar on Tuesday [18 Dec 2007] said it has started shipping its flexible thin-film solar cells, meeting its own deadline and marking a milestone for alternative solar-cell materials. The release of Nanosolar's first products is significant because the company develops a process to print solar cells made out of CIGS, or copper indium gallium selenide, a combination of elements that many companies are pursuing as an alternative to silicon.

The 5-year-old company has raised more than $100 million in financing and has drawn in Google founders Sergey Brin and Larry Page as investors. Because of the high price of silicon, several companies are making thin-film cells from CIGS, but a number have run into technical problems. CEO Martin Roscheisen said the manufacturing process the company has developed will enable it to eventually deliver solar electricity for less than a dollar per watt, which would be significantly cheaper than fossil fuel sources of power generation. In a previous interview, Roscheisen said all of Nanosolar's anticipated production in 2008 has already been ordered.
