Batteries Included: A Solar Cell that Stores its Own Power
By: Pam Frost Gorder
COLUMBUS, Ohio—Is it a solar cell? Or a rechargeable battery?
Actually, the patent-pending device invented at The Ohio State University is both: the world’s first solar battery.
In the October 3, 2014 issue of the journal Nature Communications, the researchers report that they’ve succeeded in combining a battery and a solar cell into one hybrid device.
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.
