Abstract
Provided is a method for manufacturing a sheet for a solar cell encapsulant which has stability against yellowing after a crosslinking process and thus good appearance with improved productivity in the sheet manufacture process, specifically to a method for manufacturing a sheet for a solar cell encapsulant characterized by melt-mixing a resin composition with an organic peroxide, a co-crosslinking agent and a silane coupling agent at the degradation temperature of the organic peroxide or less, wherein the resin composition is obtained by melt-mixing EVA resin with an antioxidant, an UV absorber and a light stabilizer at 80-220° C., and forming a sheet from the obtained melt-mixed resin composition.
