Our system optics concentrate sunlight near 500 times, so therefore drastically reducing the amount of semiconductor per W. Please have a look at http://www.sol3g.com.

Big question... Sure, it's all good to recycle, but it's unfortunate that the PV industry relied on the scraps from silicon valley instead of getting their own Solar Grade Silicon manufacturing plants... So if it isnt too late, there's solarWorld in germany with a plant that will make 3,000 metric tons, and also <a href="http://www.rec-pv.no/text/view/3515.html" rel="nofollow"> these guys in Moses Lake WA</a>, who have been making solar grade silicon exclusiveley since 2002, and are looking at bumping up manufacturing to 5,000 metric tons of SoG-Si (that company has a cool story) incidentally, it isn't such a bad thing that SoG-Si is running out in the sense that its a very messy and toxic process. hopefully future solar processes will incorporate more biomimicry and have a lighter footprint. But if anyone here is interested in manufacturing SoG-Si; there is a method of manufacture developed by Sandia, NREL and <a href="http://www.intersolar.ru/projects/eng/index.shtml" rel="nofollow">these guys, </a>and it uses no chlorene and less than 1/3 of the electricity as compared to conventional processes... like most things the NREL devlops-- the technology is probably ripe for the picking.. heyyy that’s right? xsunx never once mentions the word silicon (!) and of course there’s also konarka and nanogoogle– i mean nanoSolar… �but whether these new techs will be able to fill a golbal need for 10,000 metric tons of silicon?
