Theoretical and experimental analysis of the role of the surface states in photoelectrochemical cells has been carried out. The possible role of interface states in the potential barrier in the semiconductor space charge layer, in the change of the interphase potential with the photovoltage, and in the transfer of charge across the interphase have been discussed. The effect of ruthenium treatment of the GaAs electrode on the interface states in n-GaAs/0. 8M K//2Se-0. 1M K//2Se//2-1M KOH/C cell has been experimentally analyzed.
