Abstract

Provided is an electrically conductive adhesive composition including: electrically conductive particles (A) containing metal having a melting point of equal to or lower than 220° C.; a thermosetting resin (B); a flux activator (C); and a curing catalyst (D), in which a reaction start temperature of the thermosetting resin (B) and the curing catalyst (D) is 130 to 200° C.

Claims (23)

1 . An electrically conductive adhesive composition comprising:

electrically conductive particles (A) containing metal having a melting point of equal to or lower than 220° C.;

a thermosetting resin (B);

a flux activator (C); and

a curing catalyst (D),

wherein a reaction start temperature of the thermosetting resin (B) and the curing catalyst (D) is 130 to 200° C.

2 . The electrically conductive adhesive composition according to claim 1 , wherein the metal of the electrically conductive particles (A) contains at least one component selected from a group consisting of bismuth, indium, tin, and zinc.

3 . The electrically conductive adhesive composition according to claim 1 , wherein the thermosetting resin (B) contains an epoxy resin.

4 . The electrically conductive adhesive composition according to claim 1 , wherein the flux activator (C) contains a compound having a hydroxy group and a carboxyl group in a molecule.

5 . The electrically conductive adhesive composition according to claim 1 , being used for electrical connection of the electrodes of solar battery cells and a wiring member.

6 . A connected body in which a plurality of solar battery cells are connected via a wiring member,

wherein electrodes of the solar battery cells and the wiring member are connected via the electrically conductive adhesive composition according to claim 1 .

7 . A method for producing a solar cell module comprising:

a step of applying the electrically conductive adhesive composition according to claim 1 onto electrodes of solar battery cells;
