Method for manufacturing photovoltaic electrolysis oxygen generation electrode

Abstract

A method for manufacturing a photovoltaic electrolytic oxygen-generating electrode includes steps (a) sequentially forming an oxygen evolution reaction catalyst film structure and a water-soluble temporary support on a substrate, and attaching adhesive tape to the water-soluble temporary support to form a transfer-on-film layer on the substrate; step (b) providing a photovoltaic cell; step (c) pulling the adhesive tape away from the substrate to separate the transfer-on-film layer from the substrate, and placing the separated transfer-on-film layer in water to dissolve the water-soluble temporary support, thereby separating the adhesive tape from the oxygen evolution reaction catalyst film structure; and step (d) immersing the oxygen-generating region of the photovoltaic cell in water and placing it below the oxygen evolution reaction catalyst film structure, and removing it from the water to support the oxygen evolution reaction catalyst film structure, thus obtaining a photovoltaic electrolytic oxygen-generating electrode. This invention provides a novel method for manufacturing a photovoltaic electrolytic oxygen-generating electrode.
