The Daily Mail reports that Milan Karki, an 18 year old Nepalese student has developed a new kind of solar panel which uses human hair instead of silicon as a conductor.

Melanin, the pigment that colors hair, is light-sensitive, and can act as a conductor of electricity. With hair being far cheaper than silicon, the cost of Karki’s panels is extremely low – about £23.

These home-made solar panels are capable of producing 9 V of electricity – enough juice to charge a mobile phone, or a battery powered light.
