Zusammenfassung

The beneficial effect of a forming gas anneal (FGA) in hydrogen atmosphere on the fill factor (FF) of screen printed solar cells has been shown previously [1, 2]. In this contribution the effect of a FGA on the mechanical properties of the silver printed front side contact of solar cells is investigated for most relevant wafer surfaces (mc, Cz, EFG, each flat as well as textured). In particular, the adhesion of the busbar to the surface of the silicon wafer is examined by using standardized pull test conditions after soldering pre-soldered Cu-ribbons onto the busbars of the solar cells. It was found that the FGA has no significant influence on the mechanical properties of the busbars including the adhesion strength. Samples which experienced higher than optimal firing conditions show slightly higher adhesion strength and a wider distribution of the forces needed to detach the busbar.
