Nanosolar has $100 million in funding, could revolutionize cost of solar power

For traditional manufacturers of solar power plants it costs $1 billion to build a 400-megawatt facility. Nanosolar claims that they can do it for $100 million. Nanosolar have a roll-to-roll process. It is simpler and cheaper. There are three miles of solar cells on a single roll of polymer film. Nanosolar currently has a pilot manufacturing facility and will begin to produce solar cells on the upcoming factory in 2007. They use nanostructured components and molecular self assembly to create their solar cells They compare their Nanosolar Roll-Printed Thin Film against Vacuum-based Thin Film and silicon wafer technologies

A competing thin film solar company is Heliovolt. They are looking to deploy solar to homes instead of central plants Simple diagram of solar energy markets. Comparisons of the economics of Heliovolts technology with alternatives. (Heliovolt expects to get below key $1 per watt level.)
