Photo-electrochemical cell, manufacturing method of photo-electrochemical cell, and photo-electrochemical reaction device

A method for manufacturing a photo-electrochemical cell comprising:

• preparing a stacked body which includes a photoelectric conversion layer having a first surface and a second surface, a first electrode provided on the first surface of the photoelectric layer, and a second electrode provided on the second surface of the photoelectric layer;
• forming a first catalyst layer which includes a plurality of catalyst parts and a transparent dielectric part by disposing the plurality of catalyst parts on the first electrode and disposing the transparent dielectric part in a gap between the plurality of catalyst parts;
• and
• providing a second catalyst layer electrically connected to the second electrode.
