A photoelectrochemical cell, semiconductor (In 2O 3)/dye-EDTA//redox couple/Pt, has been developed using phenosafranin dye and EDTA aqueous solution in one compartment and Cu +/Cu 2+, Fe(CN) 6 4−/Fe(CN) 6 3−, I −/I 2, and Fe 2+/Fe 3+ in the other compartment of an H-shaped cell separated by a glass membrane. All the cell characteristics such as open-circuit voltage, short-circuit current, fill factor, power efficiency, and solar energy efficiency have been determined. There is 2-3-fold increase of efficiency of the cell compared to the same cell with illuminated Pt electrode.
