Rice U team creates low-cost, high-efficiency integrated device for solar-driven water splitting; solar leaf

Green Car Congress

Rice University researchers have created an efficient, low-cost device that splits water to produce hydrogen fuel. The concept is broadly similar to an artificial leaf. We simplify the system by encapsulating the perovskite layer with a Surlyn (polymer) film. It utilizes water and sunlight to get chemical fuels.
