The present invention provides a photocurable sealant composition that exhibits sufficient photocurability even in a light-shielding portion, is excellent in adhesiveness to a substrate, and can form a sealant having a highly reliable sealing performance. The present invention also provides an article comprising a sealant having a highly reliable sealing performance. The present invention also provides an organic solar cell with high reliability. The photocurable sealant composition includes (A) liquid rubber, (B) a (meth)acryloyl group-containing compound, (C) an aromatic sensitization assistant capable of absorbing light having a wavelength of 300 nm or more, and (D) a light polymerization initiator. The aforementioned article includes a cured product of a photocurable sealing compound composition selected from solar cells, displays, electronic components, coating materials, and adhesives. In the above-mentioned organic solar cell, a light-shielding member is disposed on the first surface of the first electrode substrate, and the sealant is located at least in a light-shielding portion of the light-shielding member opposite to the light incident surface. |
