Abstract:
1. A solar cell module which is obtained by using a solar cell encapsulating material comprising a non-crystalline or low-crystalline α-olefin-based copolymer or its composition (I), wherein the non-crystalline or low-crystalline α-olefin-based copolymer or its composition (I) is a resin composition (C) containing 50 to 100 parts by weight of non-crystalline α-olefin polymer (A) meeting the following requirements (a) through (c) and 50 to 0 parts by weight of crystalline α-olefin polymer (B) (the total of (A) and (B) being 100 parts by weight): (a) a polymerization unit based on α-olefin having 3 to 20 carbon atoms is not less than 20 mol %; (b) practically no melt peak as measured by a differential scanning calorimeter is observed; (c) the Mw/Mn is not more than 5, and wherein the non-crystalline or low-crystalline α-olefin-based copolymer or its composition (I) does not contain a cross-linking agent or cross-linking accelerator.
