ULSAN, South Korea, Jan. 4 (UPI) -- A team of researchers from Germany and South Korea have developed a new, more efficient artificial leaf, capable of turning sunlight into hydrogen fuel.
The leaf's design replicates the process of underwater photosynthesis used by aquatic plants, splitting water into hydrogen and oxygen. Sunlight is harvested by dual photoelectrodes in which a pair of photoanodes absorb solar energy.
