(Phys.org)—Last October,researchers at Ohio State demonstrated the world's first solar battery—a solar cell and a lithium-oxygen (Li-O2) battery combined into a single device. The main attraction of the solar battery concept is that, because it can harvest, and convert,and store solar energy as chemical energy all in one device, it eliminates losses that occur when transferring electrons between multiple devices. The researchers estimate that this integration can potentially reduce overall costs by approximately 25%.
