METAL FOIL LAMINATION BODY FOR SOLAR CELL, SOLAR CELL MODULE, AND MANUFACTURING METHOD OF METAL FOIL LAMINATION BODY FOR SOLAR CELL

摘要

PROBLEM TO BE SOLVED: To provide a metal foil lamination body for a solar cell which easily makes secure electric connection with aluminium foils at low costs without performing chemical treatment to surfaces of the aluminium foils.SOLUTION: A metal foil lamination body 10 for a solar cell is used for arranging wiring in a solar cell 20 having a wiring connection electrode 21 and comprises: a flexible sheet-like base material 11; aluminum foils 13 which are laminated on one surface 11a of the base material through an insulative adhesive layer 12 and form a wiring pattern on the base material; and solder parts 14, each of which is provided at a position on the aluminum foil that may face the connection electrode. The solder part is formed so as to linearly extend on the aluminum foil when viewed in a thickness direction D of the base material.
