Title: RESIN COMPOSITION, SHEET, SOLAR CELL SEALING MATERIAL, SOLAR CELL MODULE, AND METHOD FOR PRODUCING SHEET FOR SOLAR CELL SEALING MATERIAL
Abstract:
The purpose of the present invention is to obtain: a film or sheet which has high transparency, excellent impact resistance (low density) and high strength and is suitable for a solar cell sealing material; a solar cell sealing material comprising the sheet; and a solar cell module comprising the solar cell sealing material. The present invention pertains to a film or sheet containing an ethylene-propylene-α-olefin copolymer [X] which comprises ethylene, propylene and a C5-C20 α-olefin and satisfies the requirement (x-1): a constituent unit (i) derived from ethylene is contained in an amount of 74-92 mol%, a constituent unit (ii) derived from propylene is contained in an amount of 5-16 mol%, and a constituent unit (iii) derived from the C5-C20 α-olefin is contained in an amount of 3-10 mol% (the total amount of the constituent units (i), (ii) and (iii) is 100 mol%.)
