▎ 摘　　要

NOVELTY - An electroconductive composition comprises a resin component (a) comprising an epoxy resin (A) and an epoxy resin (B) and/or a functionalized polybutadiene resin and/or a functionalized butadiene-acrylonitrile copolymer, an electroconductive filler (b), a curative (c) for epoxy resin, a core-shell rubber toughener (d), and a reactive diluent component (e) which comprises a monofunctional epoxy reactive diluent and/or a polyfunctional epoxy reactive diluents. The composition further comprises a curing agent if the functionalized polybutadiene resin is present in the resin component. USE - Electroconductive composition is used for forming cured material used as interconnection material to connect solar cells into photovoltaic module (all claimed). ADVANTAGE - The composition has excellent mechanical and electrical properties, and contribute to low power loss values, and has low bulk and contact resistivity. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) use of the electroconductive composition or a cured product of the composition as an interconnection material to connect solar cells into a photovoltaic module; and (2) photovoltaic module comprising a series-connected string of two or more solar cells in a shingle pattern having an electroconductive bonding between the two or more solar cells. The electroconductive bonding is formed with the electroconductive composition or with the cured product.
