SEALING MATERIAL FOR SOLAR CELL, SHEET FOR SOLAR-CELL SEALING, AND SOLAR CELL MODULE EMPLOYING THESE

[Task] To provide a solar battery sealing material obtained by using an olefin-based (co)polymer, which is excellent in flexibility, stress-absorbing property, transparency, and impact-resistant strength at low temperature, and with which the productivity is improved by omitting a cross-linking treatment if necessary. [Solving Means] A solar battery sealing material containing 1 to 40 parts by weight of polypropylene (i) which has a propylene unit of more than 90 mol%; and 60 to 99 parts by weight of a propylene·ethylene-based copolymer (ii) which has a propylene unit of 45 to 90 mol%, an ethylene unit of 10 to 25 mol%, and an ±-olefin unit (a) having 4 to 20 carbon atoms of 0 to 30 mol% ((i) + (ii) = 100 parts by weight). The solar battery sealing material further contains 5 to 95 parts by weight of an ethylene·±-olefin copolymer (B), based on 95 to 5 parts by weight of the total amount of (i) and (ii) ((i) + (ii) + (B) = 100 parts by weight).
