| Efficiently harvesting hydrogen fuel from Sun using Earth-abundant materials Posted: 25 Sep 2014 11:12 AM PDT Scientists have a new efficient way of producing hydrogen fuel from sunlight and water. By combining a pair of solar cells made with a mineral called perovskite and low cost electrodes, scientists have obtained a 12.3 percent conversion efficiency from solar energy to hydrogen, a record using Earth-abundant materials as opposed to rare metals. |
