First Solar: Quest for the $1 Watt

This months IEEE Spectrum has an interesting article on a start-up company called First Solar. They are very close to the $1 per Watt solar cell with their thin-film production process. This mark is the so called tipping point where solar energy becomes about as expensive as regular grid energy. Thus, if you can produce such a product, you can freely compete with any regular energy provider. The article can be found here:

Don't forget to have a look at the links in the: "To Probe Further" section on page 4. They are very interesting!
