Schematic view of artificial photosynthesis system. Click to enlarge. Panasonic has developed an artificial photosynthesis system using a gallium nitride photoelectrode and a metal catalyst which uses sunlight to convert CO 2 mainly to formic acid (an important intermediate in chemical synthesis) at an efficiency (solar energy to chemical energy) of 0.2%—a comparable level to that of plants.
