Make Solar Electricity Cheaper Than Coal with Nanosolar

What makes you believe that you cant saving big money and your free to use your Electricity ?
everything is possible with the nanotech

"It's 100 times thinner than existing solar panels, and they can deposit the semiconductors 100 times faster," said Nanosolar's cofounder and chief executive officer, R. Martin Roscheisen. "It's a combination that drives down costs dramatically."

A new combination of nano and solar expertise has made it feasible for solar electric generation to be cheaper than burning coal. Nanosolar, Inc. has developed a way to produce a kind of ink that absorbs solar radiation and converts in to electric current. Photovoltaic (PV) sheets are produced by a machine similar to a printing press, which rolls out the PV ink onto sheets about the width of aluminum foil. These PV sheets can be produced at a rate of hundreds of feet per minute.

Because of their light weight and flexibility, the PV sheets (dubbed PowerSheets) are much more versatile than current PV panels, which must be mounted on sturdy surfaces like roofs or the ground. In addition, because there is no silicon used in the production of the sheets, they cost only 30 cents per watt of power produced.

Traditional PV cells cost about $3 per watt, while burning coal costs about $1 per watt.

Nanosolar is ramping up production of its PowerSheets at factories in San Jose, New york, and Berlin, and expects to have them commercially available before the finish of the year. The excitement around the PowerSheets is so strong that the company already has a to year backorder, and the company has raised over $150 million from venture capitalists, including Google cofounders Larry Page and Sergey Brin.

"This is the first time that they can actually drop the cost of solar electricity down to a level that would be competitive with grid electricity in most industrialized nations," said Nanosolar co-founder Brian Sager.

"Solar panels have not been popular to the American people because they have been pricey. That is what we are changing now," Roscheisen said.
