Abstract

Use of an electrically conductive composition as an electrically conductive adhesive for mechanically and electrically connecting at least one contact of a solar cell with an electrical conductor, wherein said at least one contact is selected from the group consisting of emitter contacts and collector contacts, characterized in that the electrically conductive composition comprises (A) 2 to 35 vol.-% of silver particles having an average particle size in the range of 1 to 25 µm and exhibiting an aspect ratio in the range of 5 to 30 : 1, (B) 10 to 63 vol.-% of non-metallic particles having an average particle size in the range of 1 to 25 µm, exhibiting an aspect ratio in the range of 1 to 3 : 1, (C) 30 to 80 vol.-% of a curable resin system, and (D) 0 to 10 vol.-% of at least one additive, wherein the sum of the vol.-% of particles (A) and (B) totals 25 to 65 vol.-%.
