Abstract
The present invention relates to a back sheet for solar cell and a method of manufacturing the same. The back sheet for solar cell comprises a substrate and a fluoropolymer layer, wherein the components by weight of the fluoropolymer layer are as follows: 25˜45 parts of fluororesin; 1.5˜3 parts of modified resin; 0.5˜3 parts of polymeric filler; 0.1˜1 parts of inorganic filler; and 50˜70 parts of solvent. The back sheet for solar cell provided by the present invention has low cost and excellent performances, such as high peeling strength, good waterproof performance, and good weathering resistance. The method of manufacturing the back sheet for solar cell provided by the present invention is simple in process, and thus can achieve continuous industrial production.
