Abstract

The invention belongs to the design and preparation method of the solar battery and relates to a photo-induced protonized solar battery for combining the solar energy and the photo acid molecules. In the invention, an enclosed container used as a photo-electrochemical pool is internally provided with a cation-exchange membrane, and the cation-exchange membrane divides the enclosed container into a first container and a second container which have different volumes; the first container contains the aqueous solution of the photo acid molecules and the second container contains water; one side wall of the first container is partially light-transmitted, and the transmitted light and the cation-exchange membrane form an incident angle of 90 degrees; the rest walls of the enclosed container are lightproof. The invention mainly uses the photolysis reaction of the photo acid molecules under the action of the light; the generated hydrogen ions concentration gradient can be used for ion exchange by the cation-exchange membrane to generate electric current and potential difference to do work to the outside; the ion concentration gradient generated by the photolysis of the photo acid molecules realizes the inner circulation of the photo acid molecules and the ions, and the inner circulation ensures the persistency and the constancy of the generated electric current.

Description

technical field [0001] The invention belongs to the design and preparation method of solar cells, and specifically relates to a photo-induced protonated solar cell with the advantages of high efficiency, cleanness, and regeneration, which combines solar energy and photo-protonated photoacid molecules (photosensitive substances) Battery. Background technique [0002] Energy is closely related to the survival and development of human society, and the rapid development of human society is accompanied by a sharp increase in energy consumption. However, the limited resources of mineral resources and the pollution to the environment after burning make the development and application of renewable new energy a goal pursued by governments of various countries for economic development and security construction "Journal of Membrane Science 319 (2008) 214-222". New energy sources such as solar energy, tidal energy, wind energy, ocean energy, and biomass energy have attracted the attent...
