Figure 1. Photoelectrochemical Water Splitting

Caption

Water can be split to obtain H2 and O2 by applying a low voltage in a circuit like the one shown in the figure by using an appropriate photoanode material. The H2 generated can be used as clean fuel, meaning that photoelectrochemical water splitting is a way to harvest solar energy.
