    • The invention relates to a photovoltaic cell comprising a photovoltaic absorbent material, said cell including a front face substrate (10), particularly a transparent glass substrate. A main surface of the substrate is provided with a transparent electrode coating (100) formed by a stack of thin layers including at least one metal functional layer (40) based, in particular, on silver, and at least two anti-reflective coatings (20, 60). The invention is characterised in that the anti-reflective coating (60) disposed on top of the metal functional layer (40) on the side opposite that of substrate includes a current-conducting layer (66) located farthest from the substrate and having a resistivity ρ of between 2.10−4 Ω·cm and 10 Ω·cm, based, in particular, on TCO.
    • 本发明涉及一种包含光伏吸收材料的光伏电池,所述电池包括前面基板(10),特别是透明玻璃基板。 基板的主表面设置有透明电极涂层(100),该透明电极涂层(100)由一叠薄层组成,该薄层包括至少一个基于银的金属功能层(40),并且至少两个抗反射涂层 20,60)。 本发明的特征在于,设置在与衬底相反一侧的金属功能层(40)的顶部上的抗反射涂层(60)包括导电层(66),导电层(66)位于距衬底最远的位置并具有电阻率 &rgr; 在2.10-4&OHgr;·cm和10&OHgr·cm之间,特别是基于TCO。
