The invention discloses an encapsulation polyolefin film prepared by the radiation pre-crosslinked and preparation method therefor, and further an encapsulation method and module with same. The preparation Method for producing the radiation pre-crosslinked polyolefin film for encapsulation comprises the following steps: preparing a film by mixing polyolefin raw materials together; using the radiation energy source to irradiate the film, wherein the radiation energy source can directly stimulate crosslinking reaction of the polyolefin raw materials to occur; adjusting the radiation dose of the radiation energy source, in order to make the crosslinking degree of the film reach 3% to 95%; adjusting the energy of radiation, in order to make the thickness of crosslinked part reach 5% to 100% of the film, wherein 100% means all the film are crosslinked. Since the film has been crosslinked before used, the dimensional stability and heat resistance of the film are remarkably improved, which is advantageous for capsulated module to obtain a clear interface of encapsulation. |
