| 发明名称 | Sealing material sheet for solar cell modules | ||
| 摘要 | Provided is a sealing material sheet for solar cell modules, which is obtained by irradiating a polyethylene resin with ionizing radiation and has high transparency, heat resistance and adhesion at the same time. This sealing material sheet for solar cell modules contains a low density polyethylene having a density of 0.900 g/cm3 or less, while having a gel fraction of from 0% to 40% (inclusive) and a degree of dispersity (Mw/Mn), which is the ratio of the weight average molecular weight (Mw) to the number average molecular weight (Mn) in terms of polystyrene, of from 2.5 to 3.5 (inclusive). | ||

| 主权项 | 1. A sealing material sheet for a solar cell module, comprising a low density polyethylene having a density of 0.900 g/cm3 or less in an amount of 90 parts by mass or more relative to 100 parts by mass of total resin components in the sealing material composition, wherein a gel fraction is 0% or more to 10% or less, and a degree of dispersity (Mw/Mn) being a ratio of weight average molecular weight (Mw) to number average molecular weight (Mn) in terms of polystyrene is 2.5 or more to 3.5 or less. | ||
