Solar panels have changed the way we bring energy and electricity to our homes. But there was a concern: it worked only when the sun was readily available. But this technology could be a thing of the past; a new solar cell prototype has been developed by a team of scientists in Qingdao, China it will now be able to create electricity with the assistance of raindrops. This has been possible, thanks to the thin layer of graphene being used to coat solar cells.
