SOLAR CELL MODULE, MANUFACTURING METHOD FOR SOLAR CELL MODULE, AND REEL-WOUND BODY WITH TAB WIRE WOUND THEREAROUND

摘要

The present invention improves connection reliability when using a conductive adhesive agent to connect a tab wire and an electrode of a solar cell. The invention is provided with: a plurality of solar cells (2); and tab wires (3) that are connected via a conductive adhesive agent (17) including spherical conductive particles (23) to electrodes (11, 13) that are respectively formed on the surfaces of the solar cells (2) and the rear surfaces of adjacent solar cells (2) to connect pairs of solar cells (2). One surface of each tab wire (3) in contact with the conductive adhesive agent (17) has a convexo-concave portion (18) formed thereon, wherein an average height (H) of the convexo-concave portion (18) and an average particle diameter (D) of the conductive particles satisfy D ‰§ H.
