MIT chemistry professor Daniel Nocera leaded research on the artificial leaf project, says he and his colleagues took their cues from plants, which are literally buzzing with electricity.
    During photosynthesis, the energy in sunlight splits water molecules into hydrogen and oxygen. The hydrogen joins with carbon dioxide to make sugar, an essential fuel for plant growth.
    In Nocera’s laboratory, scientists replicated that chemical process using a silicon device about the size and shape of a playing card, only thinner. It’s coated with nickel and cobalt catalysts that when exposed to water and ultraviolet light, accelerate a chemical reaction.
    In laboratory experiments, Nocera’s solar cell prototype operated continuously for 45 hours without a drop in electrical output. Nocera notes that it works in any type of water. Nocera believes the artificial leaf could be especially useful as an inexpensive source of electricity for low-income populations in developing countries. The goal, Nocera says, is to make each home its own power station. He predicts a commercial version of the artificial leaf will be on the market within three years.
