Resumen de: US12584025B2
Concentrated dispersions of silver nanowires are used to prepare qualitatively distinct silver structures with a range of properties. The concentrated dispersions can have a high weight percent of silver nanowires and can be formulated to be flowable liquids or non-flowing pastes. The concentrated dispersions can be stable with no visible settling over the course of a week, can have non-Newtonian rheology, and can be diluted to a desired weight percent of silver nanowires without detrimental effects on the uniformity of the dispersions. The concentrated dispersions can be formulated with or without polymers or pre-polymer components. The concentrated dispersions can be formulated with silver salts to adjust dispersion of the silver nanowires and to improve electrical conductivity of cured silver structures formed from the dispersions. Methods for forming the concentrated dispersions are described as are methods to form silver structures from the dispersions.

Resumen de: FR3168077A1
La présente invention concerne une pâte conductrice à base de poudre d'argent de semence et son procédé de préparation, appartenant au domaine technique des cellules photovoltaïques. Cette pâte conductrice est composée de : 10-85% en poids de poudre d'argent de semence, 2-5% en poids de poudre de verre et 8-12% en poids de support organique, le reste étant de la poudre d'argent sphérique ; la poudre d'argent de semence utilise une poudre de métal commun comme base, sur laquelle l'argent croît par réduction en phase liquide à la surface grâce à un agent de revêtement, formant de nombreux pores d'argent à la surface de la poudre de métal commun après calcination. Après le dépôt d'argent photo-induit, des "pieds d'argent" se forment et s'entrelacent dans la couche frittée, augmentant la surface de contact entre la couche frittée et la couche électrodéposée, réduisant la résistivité globale des électrodes, améliorant la force de liaison entre les couches, ralentissant l'augmentation de la résistance entre les couches, améliorant efficacement l'efficacité de conversion photoélectrique des cellules tout en réduisant le coût d'application de la pâte conductrice.
