So why is this such a big deal? This new solar battery could make it more affordable for homeowners and businesses to use solar energy rather than less sustainable sources of power. Yiying Wu, a chemistry and biochemistry professor at Ohio State and one of the creators of the solar battery, said that the device could bring down costs by 25 percent. If solar power becomes less expensive to implement, this could make a lot of inroads for more widespread use of renewable energy.
"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," Wu said in a statement. "We've integrated both functions into one device. Any time you can do that, you reduce cost."
