NanoSolar,Thin Film Photovoltaic
Nanosolar, a well funded startup solar panel company is about the hit the market with their patented process for printing cheap solar cells on aluminum foil.
Nanosolar’s technology consists of sandwiches of a proprietary “paint” made of copper, indium, gallium and selenide (CIGS) that can be painted on foil. Current technology is to dope wafers of silicon with these rare elements or to use a process that involves a huge vacuum machines where a roll of foil passes through a plasma of the elements, a process that is relatively slow and expensive.
The potential of the Nanosolar process caught the eye of Google founders Sergey Brin and Larry Page who backed the company as angel investors in its early days.
Two recent announcements show that Nanosolar is ready to become a real player in the solar world. 1. The company announced it now has has $4 billion in contracts and 2. It can make money selling solar panels for as little as $1 per watt. A recent check of online sources shows panels ranging from $4.50 - $11.25 per watt, so Nanosolar has the potential to change the market and to change the power industry. Their panels are cheap enough to compete with fossil fuels in markets across the world.
