Preferred Label : photoelectrolytic cell;
IUPAC definition : A cell in which radiant energy causes a net chemical conversion in the cell, e.g.
so as to produce hydrogen as a useful fuel. These cells can be classified as photosynthetic
or photocatalytic. In the former case, radiant energy provides a Gibbs energy to drive
a reaction such as H2O H2 1/2.O2 , and electrical or thermal energy may be later
recovered by allowing the reverse, spontaneous reaction to proceed. In a photocatalytic
cell the photon absorption promotes a reaction with ΔG 0 so there is no net storage
of chemical energy, but the radiant energy speeds up a slow reaction. div class 'sources'
