Nanosolar a leader in the drive to make solar affordable -

Nanosolar has developed proprietary technology that makes it possible to simply roll-print solar cells that require only 1/100th as thick an absorber as a silicon-wafer cell yet deliver similar performance and durability. Efficient and durable thin-film CIGS (Copper Indium Gallium Diselenide) and innovated production throughput deliver the world’s most cost-efficient solar electricity cell.

According to their home page, Nanosolar is on track to make solar electricity:

* cost-efficient for ubiquitous deployment
* mass-produced on a global scale
* available in many versatile forms

The spray-on film is printed on a material that can be rolled out on any surface, so it could be built into building materials such as roof tiles and windows.

Nanosolar says that their panels will be the world's lowest-cost solar panel, selling for as little as $.99/Watt
