This solar cell doubles as a battery and stores its own electricity

Solar power has an efficiency problem. When the electrons move from the solar panel to the battery that stores them, about 20 percent of the energy is lost. But now, thanks to new type of solar cell, nearly 100 percent of the energy is stored. That’s because the solar cell itself is the battery. Researchers at Ohio State just announced a breakthrough in solar energy technology that stands to revolutionize the industry. It comes in the form of a mesh solar cell that can also store electricity.
