Oregon engineers roll out cheaper, less wasteful solar cells with inkjet printer

It looks like the push to turn the inkjet printer into the next great manufacturer of solar cells has found another proponent in a team of engineers at Oregon State University. That group of resourceful researchers claims to have created the world's first "CIGS solar devices with inkjet printing," thus giving birth to a new production process that reduces raw material waste by 90 percent. CIGS (an acronym for copper, indium, gallium, and selenium) is a highly absorbent and efficient compound, especially suited to creating thin-film solar cells. The team has used inkjet technology to pump out a CIGS ink with an efficiency of five percent, and a potential efficiency of 12 percent; apparently enough to produce a "commercially viable solar cell." Unfortunately, the group has yet to announce plans to bring the ink to our desktop printer -- so much for that backyard solar farm. Full PR after the break.
