<P>PROBLEM TO BE SOLVED: To provide an encapsulation sheet for a solar cell excellent in power generation efficiency when used in a solar cell module, as well as having a good heat resistance. <P>SOLUTION: An encapsulation sheet for a solar cell contains 50 wt.% or more of ethylene-α-olefin copolymer satisfying requirements of (i) to (iii): (i) a density is 880 to 915 kg/m<SP POS="POST">3</SP>; (ii) a fusion peak temperature is 75°C or more and 125°C or less observed by differential scanning calorimetry in a range of 20°C to 150°C; and (iii) when the fusion calorie observed by differential scanning calorimetry in a rage of 20°C to 150°C is 100%, a ratio of the fusion calorie observed in a range of 20°C to 50°C is 5% or less, and a ratio of the fusion calorie observed in a range of 20°C to 100°C is 60% or more and 95% or less. <P>COPYRIGHT: (C)2013,JPO&INPIT |
