    • A photovoltaic cell includes transparent glazing substrate, protecting a thin-film multilayer including a film having photovoltaic properties; and two films forming electrodes, one the bottom electrode film and the other the top electrode film, placed on either side of the photovoltaic film, the bottom electrode film being a TCO including a zinc oxide substituted by an element selected from Al, Ga, In, B, Ti, V, Y, Zr and Ge or any combination thereof. The cell includes, between the substrate and the bottom electrode film, a succession of at least two films of dielectric materials, including a first film of a material forming a barrier to the alkali metals coming from the glazing substrate, especially during a tempering or annealing operation; and a second film including aluminum nitride AlN, gallium nitride GaN or a mixture thereof, the second film being in contact with the bottom electrode film.
    • 光伏电池包括透明的玻璃基板,保护包括具有光伏特性的薄膜的薄膜多层; 和形成电极的两个膜,一个底部电极膜,另一个位于顶部电极膜上,放置在光伏膜的任一侧上,底部电极膜是包含被选自Al,Ga,In中的元素取代的氧化锌的TCO ,B,Ti,V,Y,Zr和Ge或其任何组合。 该电池在基片和底部电极膜之间包括一系列至少两层的电介质材料,包括形成对来自玻璃基板的碱金属形成阻挡层的材料的第一薄膜,特别是在回火或退火过程中 操作; 以及包括氮化铝AlN,氮化镓GaN或其混合物的第二膜,第二膜与底部电极膜接触。
