A PROCESS FOR ANNEALING PHOTOVOLTAIC POLYMER ENCAPSULATION FILM AND METHOD FOR MANUFACTURING PHOTOVOLTAIC MODULE

摘要

The present invention relates to an annealing method for a photovoltaic polymer sealing film and a method for manufacturing a photovoltaic module, wherein the annealing method is prepared by extruding ethylene vinyl-acetate functional polyolefin along an extrusion direction. And a film production step of producing a photovoltaic polymer sealing film comprising polymer molecules stretched along a machine direction (MD), and the prepared photovoltaic polymer sealing film on the support surface of the support means in a continuous sheet form. Annealing the substrate to at least partially anneal while increasing the isotropy of the polymer molecules by infrared heating of the film to a relaxation temperature of the film while supplying fluid between the film and the support surface. Steps.
