SOLAR CELL BACK SHEET INCLUDING A FLUORINE-BASED COPOLYMER, AND METHOD FOR MANUFACTURING SAME

摘要

The present invention relates to a solar cell back sheet, comprising a resin layer including: 1) a substrate layer; and 2) a polyvinylidene fluoride-based (PVDF) copolymer having a crystallinity of 50% or less, and to a method for manufacturing same. Since the solar cell back sheet of the present invention can be obtained by freely setting a drying temperature of the resin layer to 250°C or less, preferably to 200°C or less, it is possible to set optimum temperature conditions for obtaining optimum physical properties, to minimize thermal deformation of the substrate layer, to reduce the manufacturing costs of the solar cell back sheet, and to improve productivity.
