Abstract: La invención se refiere a un proceso para producir uniones conductoras de electricidad entre celdas solares, en el cual un adhesivo que comprende partículas conductoras de electricidad se transfiere primero desde un portador al sustrato al irradiar el portador con un láser, el adhesivo transferido al sustrato se seca y/o se cura parcialmente para formar una capa de adhesivo, en una etapa posterior el adhesivo se une a una conexión eléctrica, y finalmente la capa de adhesivo se cura. La invención se refiere además a un adhesivo para llevar a cabo el proceso, que comprende 20 a 98% en peso de partículas conductoras de electricidad, 0.01 a 60% en peso de un componente aglutínate orgánico usado como un material de matriz, con base en cada caso en el contenido de sólidos del adhesivo, 0.005 a 20% en peso de absorbente con base en el peso de las partículas conductoras en el adhesivo, y 0 a 50% en peso de un dispersante y 1 a 20% en peso de solvente con base en cada caso en la masa total del adhesivo húmedo y no curado.

Abstract: The invention relates to a process for producing electrically conductive bonds between solar cells, in which an adhesive comprising electrically conductive particles is first transferred from a carrier to the substrate by irradiating the carrier with a laser, the adhesive transferred to the substrate is partly dried and/or cured to form an adhesive layer, in a further step the adhesive is bonded to an electrical connection, and finally the adhesive layer is cured. The invention further relates to an adhesive for performing the process, comprising 20 to 98% by weight of electrically conductive particles, 0.01 to 60% by weight of an organic binder component used as a matrix material, based in each case on the solids content of the adhesive, 0.005 to 20% by weight of absorbent based on the weight of the conductive particles in the adhesive, and 0 to 50% by weight of a dispersant and 1 to 20% by weight of solvent, based in each case on the total mass of the undried and uncured adhesive.
