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 platform developed by the Brown School of Engineering lab of Rice materials scientist Jun Lou integrates catalytic electrodes and perovskite solar cells that, when triggered by sunlight, produce electricity.

UNC team synthesizes silicon nanowires that split water

Green Car Congress

Researchers from the University of North Carolina have synthesized high-photovoltage multijunction Si nanowires (SiNWs) that are co-functionalized to split water catalytically. When integrated with the co-catalysts and suspended in water, these light-activated nanoreactors produced hydrogen gas under visible and infrared light.
