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.
