Abstract: A dye-sensitized solar cell is provided, which includes: a pair of electrode substrates (1,1?) bonded to each other with a seal member (7) with their electrically conductive electrode surfaces facing inward, one of the electrode substrates being opaque or translucent, the other electrode substrate being transparent; and an electrolyte solution contained therein. The seal member (7) is composed of a material cured by photopolymerizing a photopolymerizable composition essentially comprising a hydrogenated elastomer derivative having at least one (meth)acryloyl group at least one of its opposite molecular terminals, and the electrode substrates (1, 1?) each have a portion coated with a silane coupling agent of a (meth)acryloxyalkylsilane in contact with the seal member (7). Therefore, the dye-sensitized solar cell has higher adhesive sealability and excellent durability.

Abstract: A dye-sensitized solar cell is provided, which includes glass substrates (1, 1?) each formed with an electrically conductive transparent electrode film and bonded to each other in opposed relation with a seal member (7), and an electrolyte solution filled in a space between the glass substrates. The seal member (7) is composed of a material cured by photopolymerizing a photopolymerizable composition essentially containing a hydrogenated elastomer derivative having at least one (meth)acryloyl group at least one of its opposite molecular terminals, and the glass substrates (1, 1?) each have a portion coated with a silane coupling agent of a (meth)acryloxyalkylsilane in contact with the seal member (7). Therefore, the dye-sensitized solar cell has higher adhesive sealability and excellent durability.

Abstract: Provided is a photovoltaic power generation and solar heat collector which can be installed in a small area and can simultaneously maintain a high collection efficiency and a high photoelectric conversion efficiency. The photovoltaic power generation and solar heat collector (10) includes a dye-sensitized photovoltaic cell (11); and a heat collection panel (12) provided on top of the dye-sensitized photovoltaic cell (11). Sunlight is incident on a top surface of the heat collection panel (12).
