With the hope of providing the world with a new solution for cheap and green electricity, a teenager has come up with a new type of solar panel using human hair. Milan Karki, 18, who lives in a village in Nepal, has successfully produced solar panels using hair at a cost of just £23.
Silicon is the common but expensive component of solar panels. Milan has replaced silicon with hair, proving that panels can be produced at a low cost for those with no access to power.
Nepal is one of the poorest countries in the world and many rural areas in the country still survive without electricity. Even in areas connected to power lines, people endure shortages of up to 16 hours a day.
Though Milan and his classmates conceived the idea of the solar panel as an experiment in the beginning, they realized it has wide applicability and commercial viability.
The solar panel they made can produce 9 V of power. Melanin that gives hair its color is light sensitive and can act as a great energy conductor.
And so, the teenager replaced the silicon in normal solar panels with human hair. The new panel is four times cheaper than the ones on the market today. With the help of this, you can even charge a mobile phone or a pack of batteries that can provide energy all evening.
Let’s hope that with the invention of this solar panel, a solution to the developing world’s energy needs would come about.
