Abstract: Provided are novel crosslinkers and curable compositions including such crosslinkers. Bonded constructions including the disclosed curable compositions display high adhesion, elongation, and impact resistance even if the bonded substrate receives no surface treatment prior to bonding. Provided are elastomeric products including the curable compositions, methods of making the same, and uses thereof.

Abstract: An adhesive composition is described comprising unpolymerized cyclic olefin, a ring opening metathesis polymerization (ROMP) catalyst or precatalyst thereof, and one or more adhesion promoter polymers. In one embodiment, the adhesion promoter is a polyolefin comprising maleic anhydride or silicon-containing moieties. In one embodiment, a combination of at least one polymeric polyisocyanate and at least one polyolefin comprising maleic anhydride or silicon-containing moieties provides a synergistic improvement. In another embodiment, a polymeric polyisocyanate adhesion promoter comprising oxygen atoms in the backbone has been found useful for bonding substrates such as polyamide, polyether ether ketone, or polyether imide. Also described are methods of bonding a substrate and articles, such as an electric battery cold plate assembly.

Abstract: The present disclosure relates to photovoltaic (“PV”) solar cell comprising a frontside busbar tape in electrical contact with narrow front busbars (e.g., silver busbars). A single frontside busbar tape may be in electrical contact with a single narrow front busbar or with a dual set of narrow front busbars. The disclosure also relates to modified gridlines and methods of enhancing the electrical connection between gridlines and narrow busbars and busbar tape on a solar PV cell.
