More Information
Summary:An adhesive composition, including: a reaction product (A) among a bifunctional epoxy resin represented by the formula (2), a tri- or more functional epoxy resin represented by the formula (3), and a saturated acid anhydride represented by the following general formula (4); a UV-sensitive reaction initiator (B); and a dilution solvent (C), wherein the component (A) is a compound represented by the formula (1), a ratio of a total mole of epoxy groups in the multi-functional epoxy resin to a mole of the saturated acid anhydride is 1.30 to 3.00, and a mole of the bifunctional epoxy resin relative to a total mole of the multi-functional epoxy resin is 0.001 to 0.15. This provides a highly reliable epoxy-resin-based adhesive composition and film-shaped sealing material having a low viscosity, curability at low temperature, and high adhesiveness, and retaining power generation performance of a perovskite solar cell before and after sealing.
