Abstract
A sealant composition which may be applied between two substrates in a solar panel provides consistent rheology, high weatherability resistance, acts as a moisture barrier, and has low conductivity. The sealant composition preferably includes a rubber component, at least one rheology modifier, an adhesion promoter, a flow modifier, and a stabilizer.

4 more elements
An assembly comprising:
- a first substrate;
- a second substrate;
- a solar cell located between the first substrate and the second substrate;
- a first seal disposed between the first substrate and the second substrate, the first seal disposed along a periphery of the first substrate and the second substrate;
- and
- a second seal disposed between the first substrate and the second substrate and disposed between the first seal and the solar module, the second seal having a composition comprising:
