There are so many ways to generate electric power rather than the continuing use of fossil fuels. One among them is solar! Solar is a logical and long-term alternative to burning fossil fuels and provides a clean energy without producing any threat to the environment.
Solar panels are designed and installed to harness solar energy in Kansas City, to reduce the energy usage and utility bills. These solar panels trap solar rays and then convert them into electrical energy, stores it in a grid and supplies when required. Panels placed in sunny areas tend to provide more electrical energy compared to the panels placed in shady or cloudy areas. Keeping this in mind, scientists were working on to create a new solar cell prototype to generate electricity from raindrops. Surprised right?
Solar panels has changed the way people bring energy into their homes but are often overlooked because they cannot provide optimal output power without ideal weather conditions. In order to make their efficiency far better, engineers and material scientists have worked on several factors and have come up with graphene solar panels which can generate electricity from raindrops.
Graphene is well-known for its conductivity and applying a thin layer of graphene over the solar panel is more than enough to generate electric power. In situations where water is present, this graphene binds its electrons with positively charged ions and produces electrical energy. The salt content in rain drops splits into ions and makes natural water and graphene a great combination for generating electrical energy. This process is popularly known as Lewis acid-base interaction.
Graphene solar panels are designed in such a way to be triggered by both light and rain providing an optimum energy conversion efficiency of 6.53%. These all-weather solar panels are promising in solving the energy crisis but still in its preliminary stage of development.
Like most other solar panels, these graphene coated panels can generate solar energy from sunlight on sunny days using existing technology. When raindrops start to fall during a rainy weather, this system switches to its graphene-based energy collection system. The aqueous form of graphene serves as a pseudo capacitor that can be used in the generation of electricity.
During the early tests, the researchers were able to generate hundreds of microvolts and achieve a respectable 6.53 percent solar-to-electric conversion efficiency from their customized solar panel. But the experiment was carried on only with an inexpensive, thin-film solar cell called a dye-sensitized solar cell.
The developers believe that these graphene coated solar panels can provide a boost to solar cell technology which currently works effectively on sunny regions. Going this way, photovoltaic cells may not be troubled by a lack of direct sunshine at all.
