SEALING AGENT COMPOSITION FOR DYE-SENSITIZED SOLAR CELL

摘要

[Problems] In a conventional sealant for a dye-sensitized solar cell, there has not been present such a type that has no leak or evaporation of an electrolyte after a reliability test, and is cured upon irradiation of energy rays. It has been known that cracking in the sealant or interfacial peeling between the sealant and a substrate by the reliability test raised critical defect, and ingress of moisture into a cell by a moisture resistance test, or evaporation of an electrolytic solution through the sealant in a test to be exposed at high-temperature or the like results in deterioration of reliability. [MEANS FOR SOLVING THE PROBLEMS] A sealant composition for a dye-sensitized solar cell comprising (A) to (D) components.
An (A) component: a hydrogenated polybutadiene compound having a (meth)acrylic group;
A (B) component: a hydrogenated polybutene compound having a kinematic viscosity of 100 to 5000 cSt at 98.9°C;
A (C) component: a (meth) acrylic compound having an alicyclic hydrocarbon; and
A (D) component: a photo initiator.
