Inspired by Stephen Hawking's discussion of ways to make static electricity from hair, Milan Karki, 18, of rural Nepal, believes he has found the solution to the developing world's energy needs, saying hair (due to Melanin) is easy to use as a conductor, in place of expensive silicon. The £23 solar panel produces 18 Watts.

Adapted from a report in the UK's Daily Mail.
18-year old Inventor, Milan Karki, from rural Nepal, has come up with a new type of solar panel that uses human hair, a design he thinks could provide the developing world with cheap, green electricity. He has built several prototypes. Once manufactured, he thinks these panels could be half the cost of the cheapest solar panels now available.
Inspired by Stephen Hawking's discussion of ways to make static electricity from hair, Karki, theorizes that the Melanin (a play on his name?) in the hair enables it to act as a conductor, in place of expensive silicon. Melanin, a pigment that gives hair its colour, is light sensitive and also acts as a type of conductor.
His panel, which produces 18 Watts (9 volts at 2 amps), uses £23 in materials. The solar panel can charge a mobile phone or a pack of batteries capable of providing light all evening. Karki points out that half a kilo of hair can be bought for only 16p in Nepal and lasts a few months, whereas a pack of batteries would cost 50p and last a few nights; and that people can replace the hair easily themselves, so his solar panels need little servicing.

Note: the Engineers who have commented on this story say it is a HOAX, giving significant reasons, such as the lack of sufficient surface area, and the general non-conductivity of hair, among other things.

I guarantee it's a hoax. Just google nepal solar hair hoax and there's a debunking web page.
I would say give it a chance first. I still have engineers telling me hydrogen generation for my vehicle is a hoax while I am getting 20% average improvement off of my homemade podunk hydrogen generator and have networked with people who have increased theirs by 50%

This story should not be propagated further. It has been completely discredited both in news articles and debunking websites (Google "Nepal Human Hair Solar Panel Hoax"). Basically, the inventor of this device doesn't understand the purported science behind it, as evidenced by quotes in his interviews (see debunking sites for details). Using the inventor's own description of the technology in his panel (cuprous oxide) his solar panel would have to be 120m x 120m to deliver the claimed 9VDC at 18W.
Piling nonsense on nonsense with the latest interview doesn't help.
