PHOTOELECTRODE AND METHOD FOR MANUFACTURING SAME, AND PHOTOELECTROCHEMICAL REACTION DEVICE USING SAME

摘要

The method for manufacturing a photoelectrode according to an embodiment of the present invention comprises preparing a layered body 101 provided with a first electrode layer 110 having an optically transparent electrode, a second electrode layer 120 having a metal electrode, and a photovoltaic layer 130 provided between the electrode layers 110, 120. The layered body 101 is dipped in an electrolytic solution 2 containing ions including a metal constituting a catalyst layer formed on the first electrode layer 110, after which an electric current is introduced from the second electrode layer 120 to the layered body 101, whereby the metal and/or a compound including the metal is electrochemically deposited on the first electrode layer 110, and a catalyst layer is formed.
