Abstract[English]
The invention relates to an optoelectronic component (100) having at least two optoelectronic cells (1) being connected in series, each optoelectronic cell (1) comprises a current-contributing area (I) and at least one non-current-contributing area (II, III), wherein the at least one non-current-contributing area (II, III) and the current-contributing area (I) of the optoelectronic cell (1) share the same stack (10), wherein the at least one non-current-contributing area (II, III) is arranged within the current-contributing area (I) and is delimited from the current-contributing area (I) by separating structures, wherein the current-contributing area (I) and the at least one non-current-contributing area (II, III) of the optoelectronic cell (1) are electrically connected antiparallel to each other, wherein the stack (10) of each optoelectronic cell (1) is structured in such a way that a base electrode (11) of the current-contributing area (I) is electrically separated from a base electrode (11) of the at least one non-current-contributing area (II, III), and the base electrode (11) of the at least one non-current-contributing area (II, III) is electrically connected to a top electrode (12) of the current-contributing area (I).[French]
L'invention concerne un composant optoélectronique (100) comportant au moins deux cellules optoélectroniques (1) connectées en série, chaque cellule optoélectronique (1) comprenant une zone de contribution au courant (I) et au moins une zone de non-contribution au courant (II, III), la ou les zones de non-contribution au courant (II, III) et la zone de contribution au courant (I) de la cellule optoélectronique (1) partageant le même empilement (10), la ou les zones de non-contribution au courant (II, III) étant disposées à l'intérieur de la zone de contribution au courant (I) et étant délimitées par la zone de contribution au courant (I) au moyen de structures de séparation, la zone de contribution au courant (I) et la ou les zones de non-contribution au courant (II, III) de la cellule optoélectronique (1) étant électriquement connectées dans une orientation antiparallèle les unes par rapport aux autres, l'empilement (10) de chaque cellule optoélectronique (1) étant structuré de telle manière qu'une électrode de base (11) de la zone de contribution au courant (I) est électriquement séparée d'une électrode de base (11) de la ou des zones de non-contribution au courant (II, III), et l'électrode de base (11) de la ou des zones de non-contribution de courant (II, III) est électriquement connectée à une électrode supérieure (12) de la zone de contribution au courant (I).
