Abstract

L'invention concerne une boîte de jonction d'une cellule photovoltaïque et le procédé de fabrication de celle-ci. Une pluralité de bandes métalliques conductrices (2) est disposée dans le corps de boîte de jonction (1). Les bandes métalliques conductrices sont obtenues en découpant une tôle métallique entière au niveau des joints (7). Une surface inférieure du corps de boîte en plastique comprend des trous (6) correspondant aux jonctions entre deux bandes métalliques conductrices adjacentes. Le procédé comprend les étapes suivantes. Une tôle de métal conducteur est fabriquée selon la forme prédéterminée. La tôle de métal conducteur est subdivisée en une pluralité de zones dans le sens du profil, qui sont connectées physiquement. Des diodes (4) sont soudées sur la tôle de métal conducteur. La tôle de métal conducteur munie des diodes est installée dans le corps de boîte de jonction. La tôle de métal conducteur est découpée en introduisant un outil dans les trous, ce qui obtient physiquement une pluralité de rubans séparés les uns des autres. Le procédé réduit la difficulté d'assemblage, améliore la qualité du soudage entre la tôle de métal conducteur et les diodes et améliore l'efficacité de la production.
