photoelectrolytic cell

Also contains definition of: photocatalytic cell
https://doi.org/10.1351/goldbook.P04608
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 H2OH2+12O2 , 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.
