PHOTOCURABLE SEALANT COMPOSITION, COMMODITY, AND ORGANIC SOLAR CELL

WIPO Patent Application WO/2017/169986

A1

The purpose of the present invention is to provide the following: a photocurable sealant composition capable of forming a sealant that exhibits adequate photocuring properties even in a light-blocking section, has excellent adhesiveness with a base material, and has highly-reliable sealing performance; a commodity containing the sealant having highly-reliable performance; and a highly-reliable organic solar cell. Provided are the following: a photocurable sealant composition containing (A) liquid rubber, (B) a (meth)acryloyl group-containing compound, (C) an aromatic sensitizer capable of absorbing light having a wavelength of 300 nm or greater, and (D) a photopolymerization initiator; a commodity selected from a group consisting of a solar cell, display, electronic component, coating material, and adhesive agent, which all contain a cured product of the photocurable sealant composition; and an organic solar cell having a light-blocking member disposed on a first surface of a first electrode base material and having the sealant located on at least a light-blocking section of the light-blocking member on a side opposite the light-receiving surface thereof.
