Title (EN) METHOD FOR INSULATING THE EDGES OF A HETEROJUNCTION PHOTOVOLTAIC CELL
(FR) PROCEDE D'ISOLATION DES BORDS D'UNE CELLULE PHOTOVOLTAIQUE A HETEROJONCTION
Abstract:
(EN) The invention relates to a method for electrically insulating the edges (E) of a heterojunction photovoltaic cell. The cell comprises a semiconductor layer stack (110) formed of a first conductive layer (104) arranged on the front surface and the side surfaces of the stack, and a second conductive layer (105) arranged on the rear surface and the side surfaces of the stack. The first and second layers are in electrical contact on the side surfaces. A step of mechanically abrading the edges is carried out so as to eliminate contact between the first and second layer on the side surfaces. Each abraded surface forms an acute angle with the front surface of the cell.
(FR) L'invention concerne un procédé d'isolation électrique des bords (E) d'une cellule photovoltaïque à hétérojonction, la cellule comportant un empilement (110) de couches semi-conductrices formé d'une première couche conductrice (104) disposée sur la surface avant et sur les surfaces latérales de l'empilement, et d'une deuxième couche conductrice (105) disposée sur la surface arrière et sur les surfaces latérales de l'empilement, la première et la deuxième couche étant en contact électrique sur les surfaces latérales. Une étape d'abrasion mécanique des bords est réalisée de sorte à éliminer le contact entre la première et la deuxième couche sur les surfaces latérales, chaque bord abrasé formant un angle aigu avec la face avant de la cellule.
