SEALING MATERIAL SHEET FOR SOLAR CELL MODULE AND SOLAR CELL MODULE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a sealing material sheet for solar cell module exhibiting excellent boring characteristics when forming a through hole for taking out electricity safely from a back contact solar cell element.SOLUTION: Sealing material sheets 31, 32 for solar cell module are composed of a sealing material composition containing metallocene straight low-density polyethylene, silane modified polyethylene resin, and 90 mass% or more of polyethylene resin having a density of 0.895-0.910 g/cm. Tensile elongation measured according to JIS K7210 is 3300-3600%.
