New design brings world’s first solar battery to performance milestone
Sunlight makes the new ‘aqueous solar flow’ battery 20 percent more efficient than today’s lithium-iodine batteries
COLUMBUS, Ohio–After debuting the world’s first solar air battery last fall, researchers at The Ohio State University have now reached a new milestone.
In the Journal of the American Chemical Society, they report that their patent-pending design–which combines a solar cell and a battery into a single device–now achieves a 20 percent energy savings over traditional lithium-iodine batteries.
The 20 percent comes from sunlight, which is captured by a unique solar panel on top of the battery, explained Yiying Wu, professor of chemistry and biochemistry at Ohio State.
The solar panel is now a solid sheet, rather than a mesh as in the previous design. Another key difference comes from the use of a water-based electrolyte inside the…
