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.

Swiss team develops effective and low-cost solar water-splitting device; 14.2% solar-to-hydrogen efficiency

Green Car Congress

The prototype system is made up of three interconnected, new-generation, crystalline silicon solar cells attached to an electrolysis system that does not rely on rare metals. crystalline Silicon (c-Si) solar cells show high solar-to-electricity efficiencies, and have demonstrated stabilities in excess of 25 years.

Researchers develop free-standing nanowire mesh for direct solar water-splitting to produce H2; new design for “artificial leaf”

Green Car Congress

The mesh with BiVO 4 nanowire photoanode for water oxidation and Rh-SrTiO 3 nanowire photocathode for water reduction produces hydrogen gas without an electron mediator. an “artificial leaf” to produce hydrogen—based on a nanowire mesh that lends itself to large-scale, low-cost production.

They aim to demonstrate that CO 2 -neutral hydrogen can be produced in a cost-effective manner and intend to facilitate the storage of electricity. Solar and wind energy generation depends on the weather and is subject to significant fluctuations. By converting electricity to gas, solar and wind power become storable.
