It looks like those curious to see just how Nanosolar
turns out their solar panels for less than a dollar per watt need wonder no more, as the company has just posted a video that shows the thin film solar cells rolling off the presses at speedy 100 feet-per-minute. That's apparently possible thanks to what the company claims is the industry's first 1GW production tool, and its use of its own long-in-development nanoparticle ink, which eliminates the need for expensive high-vacuum chambers (though the printer still costs a hefty $1,65 million). What's more, the company says their technique would even work "in principle" at speeds up to 2,000 feet-per-minute, although they aren't making any promises about attempting an upgrade anytime soon. Head on past the break to check it out in action.
