Estimating the term…
The invention relates to a photovoltaic cell having an absorbent photovoltaic 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 a metallic functional layer (40), especially one based on silver, and at least 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 has an optical thickness equal to about four times the optical thickness of the antireflection coating (20) placed beneath the metallic functional layer (40) in the direction of the substrate.
A photovoltaic cell having an absorbent photovoltaic material, said cell comprising a front face substrate having, on a main surface, a transparent electrode coating comprising a thin-film stack that comprises a metallic functional layer and at least two antireflection coatings, said antireflection coatings each comprising at least one antireflection layer, said functional layer located between the two antireflection coatings, wherein the antireflection coating placed above the metallic functional layer on the opposite side from the substrate has an optical thickness equal to about four times the optical thickness of the antireflection coating placed beneath the metallic functional layer in the direction of the substrate.
