The invention relates to a photovoltaic cell ( 1 ) having an absorbent photovoltaic material, especially a cadmium-based material, said cell comprising a front face substrate ( 10 ), especially a transparent glass substrate, having, on a main surface, a transparent electrode coating ( 100 ) consisting of a thin-film stack that includes at least one metallic functional layer ( 40 ), especially one based on silver, and at least two antireflection coatings ( 20, 60 ), said antireflection coatings each comprising at least one antireflection layer ( 24, 26; 66, 68 ), said functional layer ( 40 ) being placed between the two antireflection coatings ( 20, 60 ), characterized in that the antireflection coating ( 60 ) placed above the metallic functional layer ( 40 ) on the opposite side from the substrate comprises at least two antireflection layers ( 66, 68 ), the antireflection layer ( 68 ) furthest from the metallic functional layer ( 40 ) being more resistive than the antireflection layer ( 66 ) closest to the metallic functional layer ( 40 ). |
