OSU hybrid “solar battery” uses photo-assisted charging to improve performance of Li-air batteries; “negative overpotential”
Green Car Congress

The team, led by Yiying Wu, professor of chemistry and biochemistry, integrated a dye-sensitized photoelectrode into a lithium-oxygen battery along with the oxygen electrode to enable “photo-assisted charging” of the Li-air cell. The photovoltage generated on the photoelectrode compensates the battery’s charging voltage.
