METHOD OF MANUFACTURING COATING AGENT OF DYE-SENSITIVE SOLAR CELL SURFACE, COATING AGENT THEREOF AND DYE-SENSITIVE SOLAR CELL COATED WITH COATING AGENT

摘要

A manufacturing method for a dye-sensitized solar cell surface coating agent, the dye-sensitized solar cell surface coating agent and a dye-sensitized solar cell coated with the dye-sensitized solar cell surface coating agent are disclosed. The manufacturing method for the dye-sensitized solar cell surface coating agent, the dye-sensitized solar cell surface coating agent and the dye-sensitized solar cell coated with the dye-sensitized solar cell surface coating agent according to the present invention comprise: a step S1 of obtaining a graphene oxide precursor by injecting graphite, sodium nitrate and potassium permanganate into strong acid and mixing them; a step S2 of obtaining graphene oxide by adding an acidic solution in the graphene oxide precursor, mixing them and filtering them; a step S3 of obtaining a graphene quantum dot solution by adding the graphene oxide in a solvent, mixing them with ultrasonic waves, hydrothermal-treating them at a temperature of 150-250; and a step S4 of manufacturing a graphene quantum dot coating agent by mixing the graphene quantum dot solution and a binder. According to the present invention, the visible ray penetration of sunlight is improved by removing the existing ultraviolet-proof film and the efficiency of the solar cell is increased by converting the ultraviolet rays of sunlight into visible rays and increasing the intensity of visible rays, thereby reducing production costs in manufacture.
