Water-gel-based solar devices, what researchers liken to "artificial leaves", can act like solar cells to produce electricity, bringing technology a bit closer to solar cells that more closely mimic the efficiency of nature and farther from the disaster of today that advocates want mandated and subsidized for questionable benefit. If it pans out, they will be less expensive and more environmentally friendly than silicon-based solar cells. The bendable artificial leaves are composed of water-based gel infused with light-sensitive molecules – the researchers even used plant chlorophyll in one of the experiments – coupled with electrodes coated by carbon materials, like carbon nanotubes or graphite. read more
