Thin-Film Solar Startup Debuts With $4 Billion in Contracts

Thursday, September 10th, 2009

A startup with a secret recipe for printing cheap solar cells on aluminum foil debuted today — with $4 billion in contracts:

Nanosolar’s technology consists of sandwiches of copper, indium, gallium and selenide (CIGS) that are 100 times thinner than the silicon solar cells that dominate the solar photovoltaics market. Its potential convinced Google founders Sergey Brin and Larry Page to back the company as angel investors in its early days.

Two big announcements marked its coming out party: The company has $4 billion in contracts and can make money selling its products for $1 per watt of a panel’s capacity. That’s cheap enough to compete with fossil fuels in markets across the world.

Small solar farms should face fewer NIMBY hurdles than big coal or nuclear plants.

Traditional solar cells can reach higher efficiencies — 40 percent versus 16 percent — but they require a lot of silicon, and they’re not cheap.
