Rain is generally a photo voltaic power cell’s worst nightmare, however a staff of Chinese language scientists might make it an incredible ally. They’ve developed a photo voltaic cell with an atom-thick graphene layer that harvests power from raindrops, making it helpful even on the gloomiest days. Water truly sticks to the graphene, making a kind of pure capacitor — the sharp distinction in power between the graphene’s electrons and the water’s ions produces electrical energy.

The catch is that the present know-how is not all that environment friendly. It solely converts about 6.5 % of the power it will get, which pales compared to the 22 % you see among the many world’s higher photo voltaic panels. If the creators can enhance the efficiency of this graphene-coated cell, although, they might have a dream answer on their arms — you would not should reside in a persistently sunny a part of the world to scale back your dependency on typical energy.
