ELECTRICALLY CONDUCTIVE COMPOSITION FOR USE AS AN ELECTRICALLY CONDUCTIVE ADHESIVE FOR MECHANICALLY AND ELECTRICALLY CONNECTING ELECTRICAL CONDUCTORS TO ELECTRICAL CONTACTS OF SOLAR CELLS

摘要

Electrically conductive composition comprising(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 thermoplastic polymer system(D) 0 to 25 vol.-% of at least one additive,wherein the sum of the vol.-% of particles (A) and (B) totals 25 to 65 vol.-%.
