A photoelectrochemical (PEC) device comprising two substrates, at least one substrate being transparent, coated with a transparent electron conductor (TEC), and a working electrode comprising a dye-sensitized porous semiconductor on one substrate A counter electrode including a catalyst layer is formed on another substrate, an electrolyte is disposed between the two substrates, and a metal conductor is used to pass current into and out of the device to provide sufficient conductivity. The metal conductor is protected from the device electrolyte with a protective layer of non-metallic material that has a rate and allows practical electrical output from the PEC device. |
