The present invention relates to an electrically conductive composition comprising a) a resin selected from the group consisting of epoxy (meth)acrylate, (poly)ester (meth)acrylate, urethane (meth)acrylate, silicone (meth)acrylate, poly(iso)butylene (meth)acrylate, (poly)isoprene (meth)acrylate, polybutylene (meth)acrylate and mixtures thereof; b) an acrylic monomer; c) an electrically conductive filler; and d) a curing agent. The composition is particularly suitable for use in a solar cell and/or a photovoltaic module, especially in the photovoltaic module, wherein the solar cells are shingled.

An adhesive composition having two distinct reaction mechanisms, a first being the reaction between a tri-functional isocyanate and an active hydrogen compound and a second begin the free radical initiation of an acrylic monomer. This adhesive develops tack strength through the first reaction allowing two substrates to remain in position relative to one another while the free radical cure of the acrylic monomer takes place to fully bond the substrates together, for example when adhering a rubber liner to the inside of a metallic tank.
