For solar power to become our foremost energy source, researchers will need to find a way to store and move it—preferably in the form of chemical fuel. Plants do that through photosynthesis, with the help of a manganese-based catalyst. At the American Chemical Society fall meeting, a team reported incorporating a mimic of this natural catalyst into a solar cell to create what amounts to artificial photosynthesis: a device that turns sunlight into fuel.
