I think it is wrongly interpreted by media and all, hair bata ta haina rahechha ta tini haru le ta photoelectric cell use garera nai light nikaleko rahechha ta, ani k kapal kapl baneko, tyo pani india ma baneko solar panels haru use garera tesma hair ra sillicon add gareko rahechha derai heat adsorb garna. HEHE, this made me laugh.

While it's exciting to see these motivated and dedicated young kids, it's quite obvious that they had to use silicon (semiconductor) nonetheless. Fact-check: silicon cell array is used in the conventional/commercial solar panel. These folks used silicon-coated hair. It's not HAIR which is producing the electricity but it's merely acting as an absorber of sunlight since it's black. I would be interested in this project, if these experimenters could light a bulb without using silicon coating OR generate the same amount of voltage with a "budhako seto kapaal" http://sajha.com/sajha/chat/sm...
