Abstract
Official abstract text for this publication.
The invention relates to a composition for printing conductor tracks onto a substrate, especially for solar cells, using a laser printing process, which composition comprises 30 to 90% by weight of electrically conductive particles, 0 to 7% by weight of glass frit, 0 to 8% by weight of at least one matrix material, 0 to 8% by weight of at least one organometallic compound, 0 to 5% by weight of at least one additive and 3 to 69% by weight of solvent. The composition further comprises 0.5 to 15% by weight of nanoparticles as absorbents for laser radiation, which nanoparticles are particles of silver, gold, platinum, palladium, tungsten, nickel, tin, iron, indium tin oxide, titanium carbide or titanium nitride. The composition comprises not more than 1% by weight of elemental carbon.
