Abstract
(EN) A conductive interconnection member of an imbricate assembly, an imbricate assembly, and a manufacturing method, relating to the field of photovoltaic technology. The conductive interconnection member comprises: a conductive layer (1), and an insulating layer (4) and electrical connectors (2) located on one side of the conductive layer (1); the conductive layer (1) is provided with a conductive circuit; the insulating layer (4) is provided with openings (41), and the electrical connectors (2) are located in the openings (41) of the insulating layer (4); the electrical connectors (2) comprise a first electrical connector (21) and a second electrical connector (22); the first electrical connector (21) is used to be electrically connected to a first electrode (31) of a back contact solar cell (3) and the conductive circuit; the second electrical connector (22) is used to be electrically connected to a second electrode (32) of a back contact solar cell (3) and the conductive circuit; and the polarities of the first electrode (31) and the second electrode (32) are opposite. By means of the first electrical connector (21) and the second electrical connector (22), the two back contact solar cells (3) arranged in an overlapping manner are connected in series to the conductive layer (1), thereby forming a cell string. The process is simple, and the first electrode (31) and the second electrode (32) are electrically isolated by means of the insulating layer (4) which has no other openings, being able to avoid a short circuit therebetween.
(FR) L'invention concerne un élément d'interconnexion conducteur d'un ensemble imbriqué, un ensemble imbriqué, et un procédé de fabrication, se rapportant au domaine de la technologie photovoltaïque. L'élément d'interconnexion conducteur comprend : une couche conductrice (1), et une couche isolante (4) et des connecteurs électriques (2) situés sur un côté de la couche conductrice (1) ; la couche conductrice (1) comporte un circuit conducteur ; la couche isolante (4) comporte des ouvertures (41), et les connecteurs électriques (2) sont situés dans les ouvertures (41) de la couche isolante (4) ; les connecteurs électriques (2) comprenant un premier connecteur électrique (21) et un second connecteur électrique (22) ; le premier connecteur électrique (21) est utilisé pour être connecté électriquement à une première électrode (31) d'une cellule solaire à contact arrière (3) et le circuit conducteur ; le second connecteur électrique (22) est utilisé pour être connecté électriquement à une seconde électrode (32) d'une cellule solaire à contact arrière (3) et au circuit conducteur ; et les polarités de la première électrode (31) et de la seconde électrode (32) sont opposées. Au moyen du premier connecteur électrique (21) et le second connecteur électrique (22), les deux cellules solaires à contact arrière (3) agencées de manière chevauchante sont connectées en série à la couche conductrice (1), formant ainsi une chaîne de cellules. Le procédé est simple, et la première électrode (31) et la seconde électrode (32) sont isolées électriquement au moyen de la couche isolante (4) qui n'a pas d'autres ouvertures, étant apte à éviter un court-circuit entre celles-ci.
