Abstract

L'invention concerne un procédé de production de cellule solaire comprenant les étapes suivantes : fourniture d'une plaquette semiconductrice ayant une face avant et une face arrière, sélectionnée dans le groupe comprenant une plaquette semiconductrice de type p ayant une base de type p et un émetteur dopé n en face avant de résistance supérieure à 70 ohms/carré, de préférence supérieure à 90 ohms/carré, de manière particulièrement préférée supérieure à 110 ohms/carré et/ou de concentration superficielle inférieure à 1020 atomes dopants/cm3, de préférence inférieure à 5x1019 atomes dopants/cm3, une plaquette semiconductrice de type n ayant une base de type n, un segment de type n sur la face avant pour la mise en contact par la face avant de la base de type n et un émetteur de type p, une plaquette semiconductrice de type n ayant une base de type n et un émetteur dopé p en face avant de résistance supérieure à 40 ohms/carré et une plaquette semiconductrice de type n ayant une base de type n et une structure émetteur dopée p pour la mise en contact par la face arrière ou une plaquette semiconductrice de type p ayant une base de type p et une structure émetteur dopée n pour la mise en contact par la face arrière; application d'une structure de couche de germination (4a) pour une structure d'électrode multicouche sur la face avant ou la face arrière de la plaquette semiconductrice; recuit de la plaquette semiconductrice pour diffuser la structure de couche de germination (4a) en couches de germination recuites (4b); dépôt galvanique de métal sur les couches de germination recuites (4b) pour créer une structure d'électrode multicouche (4b, 4c); application d'une métallisation de face arrière pour une structure d'électrode de face arrière correspondant à la structure d'électrode multicouche sur la face arrière de la plaquette semiconductrice. Selon l'invention, la plaquette semiconductrice n'est soumise à une atmosphère réductrice à une température supérieure à 200 °C ni entre l'étape de recuit et l'étape de dépôt galvanique, ni après l'étape de dépôt galvanique, ce qui permet la production d'un contact électrique de facteur de qualité <10 milliohms cm2 uniquement par dépôt galvanique d'un métal sur une plaquette semiconductrice de valeur ohmique élevée (> 70 ohms/carré), par exemple.
