in Science News
Posted
The solar panels are useless during the rainy days. Some researchers of Quingdao, China has developed a new type of solar panel that will generate electricity from rain drop.
They have layered a single atom thick coat of graphene. We all know that graphane is a great conductor. The rain water will generate free electrons due to Lewis acids and bases reaction. As a result, the overall efficiency of the system increases manifold.
