Zusammenfassung:	The invention relates to a solar cell encapsulating film and a preparation method thereof. According to the encapsulating film, a fluorine-containing thin film is prepared in an extrusion tape-casting or film blowing way from the following raw materials: 40-55 parts of fluororesin which is added with a small amount of silane coupling agent, organic hyperoxide and a crosslinking catalyst; 10-45 parts of inorganic filler; 10-45 parts of modified resin; 0.05-1.0 part of lubricant; and 0-2 parts of functional assistant. The fluororesin is a copolymer of ethylene, tetrafluoroethylene, hexafluoropropylene and 1,2,2-trifluorostyrene; and the modified resin is polyacrylate, polymethyl methacrylate or polyethyl methacrylate. The invention also provides the preparation method of the solar cell encapsulating film. The solar cell protecting film prepared by the method is low in fluorine content and is excellent in anti-ultraviolet-aging characteristic, humidity-resistant performance and weather-proof performance; and sim
