IN WASHINGTON:An American scientists have developed the world's first solar battery which recharges itself using air and light.
"Ohio State University researchers developed the solar battery by combining a battery and a solar cell into one hybrid device. " they said
Researchers said the key to the innovation is a mesh solar panel, which allows air to enter the battery, and a special process for transferring electrons between the solar panel and the battery electrode. Inside the device, light and oxygen enable different parts of the chemical reactions that charge the battery. The solar battery will be licensed to industry, where it will help tame the costs 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. We've integrated both functions into one device.
The researchers believe that the device could bring down the costs by 25 percent.
"Any time you can do that, you reduce cost," said Yiying Wu, professor of chemistry and biochemistry at the Ohio State University.
