Graphene coated solar panels create electricity from raindrops

Natural rainwater is not neutral but contains ammonium, calcium and sodium cations.solar panels generating power both during the day, from solar energy/rainfall, and even at night if it happened to rain.The renewable and clean energy source represented by solar cells would indeed take a huge leap forward if the research in this field is successful.

Idea / Approach details

By adding an ultra-thin layer of electron-enriched graphene as a top layer to the all-weather solar panels, the ions present within raindrops are able to react with the layer of graphene to produce energy.In weather condition where rain is present, graphene binds its electrons with the positively charged ions present precent within the rain drops in a process known as the Lewis-acid base reaction.

Graphene's high electronic conductivity, transparency and flexibility make them useful in heterojunction solar cells, where they can be employed in many different ways including electrodes (both anodes and cathodes), acceptor layers, donor layers, buffer layers and active layers.In fact, the International Energy Agency forecasts that renewable energy sources will contribute no less than 40% of all generated power in the world, by 2040.
