Abstract
A photoelectrode for a photoelectrochemical cell is disclosed. The photoelectrode comprises a back-contact solar cell comprising emitter and collector contacts being spaced apart by first openings. The emitter and collector contacts are respectively collected in an emitter busbar and a collector busbar. The photoelectrode further comprises a contact passivation layer to separate the emitter and collector contacts from the electrolyte when in use. The contact passivation layer further comprises second openings in correspondence with the first openings. The photoelectrode further comprises a resin layer covering the openings and a portion of the contact passivation layer such that in use only charge carriers from the emitter contacts traverse the contact passivation layer in its way to the electrolyte while charge carriers from the collector contacts are collected in the collector busbar. An electrocatalyst layer is further provided covering respectively the resin layer and/or the contact passivation layer.
