Abstract

A photoelectrochemical (PEC) device comprising two substrates, wherein: at least one substrates is transparent and coated with Transparent Electronic Conductor (TEC); a working electrode comprising dye sensitised porous semiconductor is formed on one substrate; a counter electrode comprising catalytic layer is formed on another substrate; electrolyte is placed between the two substrates; metallic conductor are utilized to conduct electrical current within and from the device; a protective layer of non-metallic material, with sufficient electrical conductivity to enable viable electrical output from the PEC device, is used to protect the metallic conductors from the electrolyte of the device.
