Title (EN) SOLAR CELL AND MANUFACTURING METHOD OF THE SAME
(FR) CELLULE SOLAIRE ET SON PROCÉDÉ DE FABRICATION
Abstract:
(EN) A method for manufacturing a solar cell, comprising steps of: a) providing a semiconductor substrate having a light-receiving side and a back side, wherein a passivation layer is formed on the back side; b) forming a silver conductor pattern on the back side of the semiconductor substrate; c) forming an aluminum conductor pattern on the back side of the semiconductor substrate, at least part of the aluminum conductor pattern being superimposed on at least part of the silver conductor pattern; and d) firing the silver conductor pattern and the aluminum conductor pattern at the same time, thereby forming an electric contact between the semiconductor substrate and the aluminum conductor pattern by way of fire through in a region where the silver conductor pattern and the aluminum conductor pattern are superimposed.
(FR) La présente invention concerne un procédé de fabrication d'une cellule solaire. Selon l'invention, le procédé comprend les étapes consistant : a) à utiliser un substrat semi-conducteur ayant un côté réception de lumière et un côté arrière, une couche de passivation étant formée sur le côté arrière ; b) à former un motif conducteur d'argent sur le côté arrière du substrat semi-conducteur ; c) à former un motif conducteur d'aluminium sur le côté arrière du substrat semi-conducteur, au moins une partie du motif conducteur d'aluminium étant superposée sur au moins une partie du motif conducteur d'argent ; et d) à allumer le motif conducteur d'argent et le motif conducteur d'aluminium en même temps, en formant ainsi un contact électrique entre le substrat semi-conducteur et le motif conducteur d'aluminium au moyen d'un allumage traversant dans une région dans laquelle le motif conducteur d'argent et le motif conducteur d'aluminium sont superposés.
