SOLAR BATTERY CELL, SOLAR BATTERY MODULE, AND PRODUCTION METHOD FOR SOLAR BATTERY MODULE

摘要

[Problem] The purpose of the present invention is to reduce the amount of Ag paste used on a back surface of a cell and to reduce cell cost while assuring cell output and the connection strength of the back surface and a tab wire. [Solution] The present invention is a solar battery cell (1) wherein, with regard to a solar battery cell that comprises at least a finger electrode, an Al electrode (2) is provided to a back surface, an opening (2a) is provided to a connection region along the connection region, which is connected by a tab wire, and a Ag electrode (3) is provided so as to span the opening (2a). The width of the Ag electrode may be 0.1-1.5 mm and is preferably 0.2-1.0 mm.
