Graphene solar panels rain.

Chinese scientists have discovered a way for solar cells to generate power via rain. Graphene has been developed as a non reflective coating for solar cells so the application of graphene to solar panels is not new news. Graphene solar panels work rain or shine solar panels today work best during periods of strong sunlight but start to wane when it gets cloudy or rainy. The resulting all weather solar cell concept was then equipped to produce power from both sunshine and the rain substitute.

What s happening here is that the positively charged ions are binding to the ultra thin layer of graphene and forming a double layer technically referred to as a pseudocapacitor with the electrons already present. A breakthrough in graphene based solar panels could change all that by allowing solar panels to generate electricity during inclement weather. Graphene layer could allow solar cells to generate power when it rains. Graphene layer could allow solar cells to generate power when it rains date.

The research done by the chinese team shows promise as a proof of concept but they were only able to achieve about a 6 5 efficiency in the rain compared to the typical average 20 25 efficiency that.
