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

Green Car Congress

Researchers from UC Berkeley, Lawrence Berkeley National Laboratory and Nanyang Technological University, Singapore have developed a new technology for direct solar water-splitting—i.e., an “artificial leaf” to produce hydrogen—based on a nanowire mesh that lends itself to large-scale, low-cost production.

MIT team outlines path to low-cost solar-to-fuels devices; the artificial leaf

Green Car Congress

Because a single Si junction has insufficient potential to drive water splitting, it cannot be used for direct solar-to-fuels conversion. Considering recent cost reductions of Si solar cells, this paper offers a path to the construction of low cost solar-to-fuels devices. —Winkler et al. Winkler, Casandra R.
