1940 E. Rabinowitch in Jrnl. Chem. Physics 8 551/1 The term ‘photogalvanic effect’ is used in the present series of papers to denote a special case of the so-called Becquerel effect, in which the influence of light on the electrode potential is due to a photochemical process in the body of the electrolyte (as distinct from photochemical or photoelectric processes in the surface layer of the electrode).
