Abstract: The open circuit voltage,photovoltage, short circuit photocurrent and photovoltage-currentcharacter of the title cell are influenced by the pH of solution in light compartment, theredox couple in dark compartment and the kind of dark electrodes in both compartments.Themechanism of these influences has been discussed.For certain system, the performance ofsemiconductor septum electrochemical photocell (SC-SEP) could be superior to that of thephotoelectrochemical cell (PEC) of single-compartment construction.

Key words: semiconductor, TiO2/Ti/TiO2 septum, photoelectrochemical cell, photovoltametric property
