Inkjet printing could change the face of solar energy industry http://apocadocs.com/s.pl?1309353042
Engineers at Oregon State University have discovered a way for the first time to create successful "CIGS" solar devices with inkjet printing, in work that reduces raw material waste by 90 percent and will significantly lower the cost of producing solar energy cells with some very promising compounds.
High performing, rapidly produced, ultra-low cost, thin film solar electronics should be possible, scientists said....
Part of the advantage of this approach, Chang said, is a dramatic reduction in wasted material. Instead of depositing chemical compounds on a substrate with a more expensive vapor phase deposition - wasting most of the material in the process - inkjet technology could be used to create precise patterning with very low waste.
"Some of the materials we want to work with for the most advanced solar cells, such as indium, are relatively expensive," Chang said. "If that's what you're using you can't really afford to waste it, and the inkjet approach almost eliminates the waste."

Guess I'll stop investing in traditional solar, since a revolution is just around the corner.
