Abstract

A Z-scheme type photoelectrochemical cell consisting of an electrochemically polymerized photoactive electrode and a dye-sensitized TiO₂ electrode is demonstrated. Nearly 1 V of open circuit voltage (V_OC) was achieved by the cooperation of a couple of photoactive electrodes toward uphill electron pumping.
