solar panel uses the rain to create energy
Solar energy is increasingly a viable hypothesis in renewable energy with low environmental impact. On sunny days the production of this energy is made smoothly, but on cloudy or rainy days production levels fall. A now known research could change this situation very soon.
The system created by a group of Chinese research uses a graphene layer embedded in the surface of photovoltaic panels to produce energy through the sun’s rays, but also through the raindrops. Thus, whatever the weather conditions energy will always be produced.
The secret is in the graphene layer, material that has excellent conductive characteristics of electricity. Applied with an extremely thin, graphene will allow a huge amount of electrons move across the surface of the plate.
But where does the water in this equation? When the water strikes the plate, graphene connects its electrons with positive ions in a physical process known as acid-Lewis base interaction. The combination of this material with water thus becomes a perfect match, full potential.
Since this technology can be used both days of intense light as rainy, the ideal energy conversion efficiency level amounts to 6.53% in 1.5 thick radiation at a voltage of hundreds of mV per drops of rain.
