[0172]

[0173] As the copper powder, what was obtained by mechanically pulverizing the atomized copper powder obtained by the manufacturing method called the atomization method was used. In addition, at the time of mechanical stirring, it is presumed that fatty acid is added for the purpose of preventing coarsening due to aggregation of copper powders. Specifically, flaky copper powder (AFS-Cu7 μm) manufactured by Nippon Artemis Processing Co., Ltd. was used. The weight cumulative particle diameter D obtained by the copper powder by laser diffraction scattering particle size distribution measurement method 50 is 7.9 μm.

[0174] 500 g of this flaky copper powder was heat-treated at 250° C. for 5 minutes in the air (oxidation treatment). After that, the oxidized copper powder was put into a mortar and coarsely pulverized. 500 g of this copper powder was added to 1,000 mL of a 1% by mass potassium hydroxide aqueous solution and stirred for 20 minutes. Then, the first decan...

Abstract

A conductive adhesive for connecting an electrode of a solar cell and a tab wire, which contains a curable resin, conductive particles, a curing agent and a black coloring agent that is formed only of titanium black.

Description

technical field [0001] The present invention relates to a conductive adhesive, a solar cell module using the conductive adhesive, and a method of manufacturing the same. Background technique [0002] Since solar cells directly convert clean and inexhaustible sunlight into electricity, they are expected as new energy sources. [0003] The solar cell described above is used as a solar cell module in which a plurality of solar cell cells are connected via bonding wires. [0004] Conventional bonding wires use solder coated on the surface of copper wires. However, since high temperature is required for solder connection, cracks or warpage of the panel on the light-receiving surface, short circuit due to protruding (leaked) solder of the bonding wire, etc., cause defects. [0005] Therefore, adhesives such as conductive adhesives are used as connecting materials instead of solder. As a bonding wire coated with such an adhesive, there is a bonding wire in which a conductive adh...
