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 module developed at Rice University can be immersed into water directly to produce fuel when exposed to sunlight. Illustration by Jia Liang. That lowers the entry barrier for commercial adoption.
