New graphene now enables the solar cell to double its efficiency.It is all the more exciting because Graphene is an insanely amazing conductor of heat and electricity but uptill now it wasn't very good at absorbing light. A very big problem currently with a graphene based solar panel design is the fact that the edges of the graphene sheet are highly reactive, so harvesting the current would prove to be much more of a challenge. Similarly in its natural state, Graphene doesn’t really want to absorb sunlight, something they will have to figure out a way to solve. We know that Graphene is a very efficient photo voltaic material, the question is now how to make it react to light and harvest electricity without destroying its composition.
