Abstract

The invention relates to wallpaper with a photoelectric conversion function and a preparation method of wallpaper. The functional wallpaper comprises wallpaper and a dye-sensitized solar cell taking the wallpaper as a substrate. The method comprises the following steps: preparing a flexible conductive coating with certain patterns and a catalyst on the wallpaper to serve as a counter electrode of the dye-sensitized solar cell in the wallpaper with the photoelectric conversion function; preparing a nanometer oxide porous film layer on a transparent flexible conductive polymer substrate with a certain shape, and allowing the film to adsorb a photosensitizer, thus preparing a sensitized photo-anode; and packaging the dye-sensitized photo-anode, electrolyte and the counter electrode on the wallpaper through a sealing material to obtain the wallpaper with the photoelectric conversion function. The invention has the advantages that the prepared wallpaper with the photoelectric conversion function can generate power by utilizing light energy in a building, and energy conservation and emission reduction of the building are promoted.

Description

technical field [0001] The invention belongs to the field of environmental protection and energy-saving wallpaper and its preparation method, in particular to a wallpaper with photoelectric conversion function and its preparation method. Background technique [0002] With the aggravation of environmental pollution and the gradual aggravation of the energy crisis, countries have considered the development of new energy sources. The universality and environmental protection of light energy make it the most promising new energy source. At present, solar cells are mainly divided into silicon-based solar cells, compound thin-film solar cells, dye-sensitized solar cells (DSC), and the like. Among them, the DSC battery is cheap, beautiful in appearance, stable in electrical conversion efficiency, and can also generate current under the action of diffuse light. This means that the DSC battery can also collect light to generate electricity in the building, so as to realize the energ...
