Researchers have invented the world's first solar battery. As a result, it is now easier to retain energy from sunlight. Researchers say that this will reduce the cost of renewable energy by up to 25 percent. At the heart of this invention is a mesh solar panel. This helps in getting air inside the battery. And through this the transfer of electrons from the solar panel to the battery electrode is completed. The reaction takes place in the presence of oxygen and light inside the device which helps the battery to be charged. And this is the solution to the long-standing problem. Significantly, a significant portion of the energy is lost during the transfer of power from the solar panel to the battery at a remote location. And as a result of this innovation, the inventors think that the efficiency of solar energy can be further increased by eliminating this problem.
