Beschreibung
Zusammenfassung:	The invention relates to a method for connecting solder-coated connection leads (3) made of aluminium or an aluminium alloy having a 0.2% yield strength of less than 120 N/mm2 to photovoltaic solar cells (7, 7a, 7b, 7c) which have metallizations on the upper side and the lower side, by a soldering method such as IR soldering, inductive soldering, thermal contact soldering, ultrasonic soldering or hot air soldering. The metallizations of the solar cells can be precoated with solder. A further solder material (2a, 2b) can be arranged between the connection lead (3) and the metallization of the solar cell (7, 7a, 7b, 7c). The solar cells (7, 7a, 7b, 7c) are connected in series with one another by this procedure.
