Title:
太陽電池素子封止用樹脂組成物及び太陽電池モジュール
Document Type and Number:
Japanese Patent JP5765238
Kind Code:
B2
Abstract:
A resin composition comprising a hydrogenated block copolymer which is used for a resin composition for encapsulating a solar cell is provided. The hydrogenated block copolymer can be obtained by hydrogenating 90% or more of the total unsaturated bonds of block copolymers which comprise at least two polymer blocks [A] having an aromatic vinyl compound-origin repeating unit as the main component and at least one polymer block [B] comprising a chain-type conjugated diene compound-origin repeating unit as the main component and in which the ratio (wA:wB) of the weight fraction (wA) of the total polymer blocks [A], relative to the total block copolymer, to the weight fraction (wB) of the total polymer block [B] is 20:80 to 60:40. The resin composition has a tensile elasticity (at 23°C) of 1.0-500 MPa and is excellent in low hygroscopicity, non-hydrolyzablity, weather resistance, transparency, adhesiveness, flexibility, and adhesive properties with glass, and can be used for encapsulating a solar cell without providing special impermeable treatment. Also provided is a solar module in which a solar cell is encapsulated with the resin composition.
