    • The present invention relates to a photovoltaic cell that includes a transparent substrate that has a first surface and a second surface. A transparent conductive oxide coating resides over the second surface of the transparent substrate. A photovoltaic coating resides over the transparent conductive oxide coating. The photovoltaic cell also includes an antireflective coating that resides over the first surface of the transparent substrate. The antireflective coating includes, in order from the first surface of the transparent substrate: a first layer that includes one or more metal oxides, for example, zinc stannate; a second layer that includes one or more metal oxides, for example, silica and alumina; a third layer that includes one or more metal oxides, for example, zinc stannate; and a fourth layer that includes one or more metal oxides, for example, silica.
    • 本发明涉及一种包括具有第一表面和第二表面的透明基板的光伏电池。 透明导电氧化物涂层位于透明基板的第二表面上。 光伏涂层位于透明导电氧化物涂层之上。 光伏电池还包括位于透明基板的第一表面上的抗反射涂层。 抗反射涂层从透明基板的第一表面依次包括:第一层,其包括一种或多种金属氧化物,例如锡酸锌; 包括一种或多种金属氧化物的第二层,例如二氧化硅和氧化铝; 包括一种或多种金属氧化物的第三层,例如锡酸锌; 以及包括一种或多种金属氧化物的第四层,例如二氧化硅。
