Old style solar cells?[edit source]
I read on a forum somewhere the suggestion that since patents have run out on older solar cell designs, they are now very cost-effective, even though their conversion efficiency is on the low side. Don't know if that's accurate, but it sounds worth looking into. Let me know if you need me to hunt for that original post, and I'll do my best. --Chriswaterguy · talk 19:41, 15 November 2007 (PST)
