▎ 摘  要

NOVELTY - An electroconductive composition comprises (a) a silicone resin comprising at least one vinyl-group, (b) a silicone crosslinker containing at least one silane group, (c) electroconductive particles, (d) a solvent, (e) an adhesion promoter, (f) a catalyst, and (g) an inhibitor. The ratio of silane groups and vinyl-groups is 1.3-10. USE - Electroconductive composition used as interconnection material to connect solar cells into photovoltaic module (all claimed). ADVANTAGE - The electroconductive silicone composition has high adhesion strength. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) cured product of electroconductive composition; (2) use of electroconductive composition or use of cured product on a solar cell and/or in a photovoltaic module, preferably as an interconnection material to connect solar cells into a photovoltaic module; and (3) photovoltaic module, which comprises a series-connected string of two or more solar cells in a single pattern having an electroconductive bonding formed with the electroconductive composition between the two or more solar cells. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of structure of ordinary silicon solar cell. Solar cell (1) Busbar (2) Finger (3)
