| 摘要 |
The invention relates to a photovoltaic cell (1) 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 (20) placed beneath the metallic functional layer (40) in the direction of the substrate has an optical thickness equal to about one eighth of the maximum absorption wavelength of the photovoltaic material and 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 one half of the maximum absorption wavelength of the photovoltaic material. |
