I just saw this at Mike Qaissaunee’s blog about cheaper solar cells created by ink jet printers.   This is from Technology Review, May 7 issue.

The process uses ink-jet printing to make electrical connections within a solar cell, replacing the existing screen-printing process. Because the ink-jet method is more precise, it can use less material for these connections. Also, because the printheads don’t make contact with the silicon, the method works with thinner silicon wafers.

Who knew how versitile ink jet printers would be?
