SOLAR-CELL COATING LAYER AND MANUFACTURING METHOD THEREFOR

摘要

A solar-cell glass cover, which increases the light-collection efficiency of a solar cell module via a simple method, is coated with a single low-refraction organic thin-film layer, improving sunlight collection performance. The disclosed solar-cell coating layer can be formed directly on a protective layer of a solar cell module and is used in direct contact with the atmosphere. Said fluorine-containing solar-cell coating layer is characterized by a fluorine content of at least 5% by mass. Fumed silica may be blended into a composition comprising: a fluoroalkyl-group-containing methacrylate and/or acrylate compound and/or a fluorine-containing polymer dissolved or dispersed in an organic solvent; an organic compound that has between one and five acryloyl or methacryloyl groups that do not contain fluorine; and a photopolymerization initiator. The result is polymerized and cured to form a protective layer.
