Printing press for solar cells
Technology, eh. It’s amazing what you can do with a printing press. In this case, it’s the merging of inkjet print and solar cell technology – see Printing energy.
Nanosolar has created a press capable of printing up to 1GW’s worth of cell structures a year, it says, using nanoparticle ink to produce back-contact thin-film cells.
“Our 1GW CIGS coater cost $1.65 million. At the 100 feet-per-minute speed shown in the video, that’s an astonishing two orders of magnitude more capital efficient than a high-vacuum process,” he said.
