Uses rain and sunlight to generate power from the force created when raindrops fall onto the surface.
The top layer of the SolarNano Generator is covered with graphene. The graphene separates the positively charged ions in the rain such as sodium and calcium which bond with the electrons in the graphene forming a double layer.
Graphene is a strong and lightweight material that can conserve and hold energy better in comparison to other materials like graphite.
The raindrops become positively charged when they hit the surface of the solar panel as they lose an electron.
In return, the surface of the solar panel becomes negatively charged.
Over time, opposite charges are accumulated from the positively charged raindrops and the negatively charged solar panels, creating static electricity. The difference of potential energy between the two layers of graphene creates electricity.
The triboelectric nanogenerator converts the static electricity into power for use.
Simultaneously, the SolarNano Generator uses the sunlight present on rainy days to generate power even though the intensity is less.
Additionally, the rain helps wash away any buildup of dirt and debris on the solar panels to increase lifespan and functionality.
