NOVELTY - A dye-sensitized solar cell comprises a seal member disposed along peripheries of inner surfaces of the electrode substrates to seal a space defined between the electrode substrates. The seal member comprises a material cured by photopolymerizing photopolymerizable composition comprising a hydrogenated elastomer derivative having (meth)acryloyl group(s) and opposite molecular terminal(s).    USE - A dye-sensitized solar cell.    ADVANTAGE - The solar cell is highly resistant to electrolyte solution and has excellent adhesive sealability and durability.    DETAILED DESCRIPTION - A dye-sensitized solar cell comprises:    (A) a pair of electrode substrates where one of the substrate is a metal electrode substrate and the other substrate is a glass substrate (1, 1') having a transparent electrically conductive electrode film;    (B) a seal member disposed along peripheries of inner surfaces of the electrode substrates to seal a space defined between the electrode substrates; and    (C) an electrolyte solution (5) filled in the sealed space.    The metal electrode substrate is a metal oxide coated metal electrode substrate having a surface coated with a metal oxide film. The seal member comprises a material cured by photopolymerizing photopolymerizable composition comprising a hydrogenated elastomer derivative having (meth)acryloyl group(s) and opposite molecular terminal(s). The metal oxide coated metal electrode substrate and the glass substrate each have a portion coated with a silane coupling agent of a (meth)acryloxyalkylsilane in contact with the seal member. The electrode substrates are spaced at a predetermined distance from each other with an electrode surface of the metal electrode substrate and the transparent electrically conductive electrode film facing inward.
