Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a sealant-integrated backside protection sheet which can make contribution to the thinning of a solar battery module in thickness and the cutting of a manufacturing cost, and which can make contribution to the increase in long-term reliability of a solar battery module by exhibiting excellent contact durability when integrated into the solar battery module.SOLUTION: A sealant-integrated backside protection sheet 10 for a solar battery module is arranged by laminating a sealing material layer 1 and a backside protection layer 2. In the sealant-integrated backside protection sheet 10, the sealing material layer 1 has a multilayer structure, in which at least a core layer 11 and a first skin layer 12 include a silane-modified polyethylene; the first skin layer 12 is larger than the core layer 11 in content rate of the silane-modified polyethylene; and the second skin layer 13 does not include the silane-modified polyethylene, otherwise it includes the silane-modified polyethylene at a content rate smaller than that in the core layer 11.SELECTED DRAWING: Figure 2
【課題】太陽電池モジュールの薄型化と製造コスト低減に寄与しうる封止材一体型裏面保護シートであって、太陽電池モジュールとしての一体化時に優れた密着耐久性を発揮することにより、太陽電池モジュールの長期信頼性の向上に寄与しうる封止材一体型裏面保護シートを提供すること。【解決手段】封止材層1と裏面保護層2とが積層されてなる、太陽電池モジュール用の封止材一体型裏面保護シート10において、封止材層1を多層構造とし、少なくともコア層11及び第1スキン層12は、シラン変性ポリエチレンを含有し、第1スキン層12は、コア層11よりも前記シラン変性ポリエチレンの含有量比が大きく、第2スキン層13は、シラン変性ポリエチレンを含有しないか、或いは、シラン変性ポリエチレンをコア層11よりも小さい含有量比で含有する、封止材一体型裏面保護シート10とする。【選択図】図2 |
