Title (EN) INTERCONNECTION OF BACK-CONTACTED SOLAR CELL, A SOLAR PANEL HAVING SUCH INTERCONNECTION
(FR) INTERCONNEXION DE CELLULE SOLAIRE À CONTACT ARRIÈRE, PANNEAU SOLAIRE DOTÉ D'UNE TELLE INTERCONNEXION
Abstract:
(EN) A solar cell includes a semiconductor substrate, with a front and rear surface. The solar cell is provided in the rear surface with a first type doped area of first conductivity type, and is further provided with a second type doped area of opposite second conductivity type. A dielectric layer on the rear surface covers at least the first type doped area. The rear surface includes on the dielectric layer a metallization pattern connected with the first type doped area and provided with contact pads for locally contacting the metallization pattern with an interconnection layer. The interconnection layer is provided with conductive contacts at locations of corresponding contact pads. Each contact pad is connected with a corresponding conductive contact by an intermediate conductive body, that is laterally extending outside the contact pad area over a rear surface portion covered by the dielectric layer and adjacent to the contact pad.
(FR) Une cellule solaire comprend un substrat semi-conducteur, doté d'une surface avant et d'une surface arrière. La cellule solaire est disposée dans la surface arrière avec une première zone dopée d'un premier type de conductivité, et est en outre dotée d'une seconde zone dopée d'un second type de conductivité opposé. Une couche diélectrique sur la surface arrière recouvre au moins la première zone dopée. La surface arrière comprend sur la couche diélectrique un motif de métallisation connecté à la première zone dopée et pourvu de plots de contact pour la mise en contact locale du motif de métallisation avec une couche d'interconnexion. La couche d'interconnexion est pourvue de contacts conducteurs au niveau d'emplacements de plots de contact correspondants. Chaque plot de contact est connecté à un contact conducteur correspondant par un corps conducteur intermédiaire, s'étendant latéralement à l'extérieur de la zone de plot de contact sur une partie de surface arrière recouverte par la couche diélectrique et adjacente au plot de contact.
