Researchers from Ohio State University are working on a solar battery that is able to store its own power inside of an internal solar cell. The unique hybrid device uses a mesh solar panel that provides an opening for air to enter the battery, and electrons can be transferred between the solar panel and the battery electrode.
"The state of the art is to use a solar panel to capture the light, and then use a cheap battery to store the energy," said Yiying Wu, Ohio State chemistry and biochemistry professor, said in a press statement. "We've integrated both functions into one device. Any time you can do that, you reduce cost."
When licensed to companies, this could help companies drop costs up to 25 percent, according to Wu and his students. Light is converted inside of the battery, ensuring almost 100 percent of electrons are saved, as opposed to the 80 percent standard when electrons travel between a solar cell and an external battery.
