    • The present invention relates generally to photovoltaic devices. The present invention relates more particularly to photovoltaic roofing products in which a photovoltaic element is affixed to a roofing substrate. In one embodiment, the present invention provides a photovoltaic roofing element comprising a roofing substrate having a solar reflectivity of greater than 0.25, and one or more photovoltaic elements affixed to the roofing substrate. In another embodiment, the present invention provides a photovoltaic roofing element comprising a roofing substrate comprising a bituminous substrate, and a plurality of colored roofing granules disposed on the bituminous substrate, the roofing substrate having color within the color space of CIE Lab coordinates L* in the range of about 20 to about 20, a* in the range of about -5 to about 5, and b* in the range of -15 to about -5; and one or more photovoltaic elements affixed to the roofing substrate.
    • 本发明一般涉及光伏器件。 本发明更具体地涉及光伏屋顶产品,其中光伏元件固定在屋顶基板上。 在一个实施例中,本发明提供了一种光伏屋顶元件,其包括具有大于0.25的太阳能反射率的屋顶基板和固定到屋顶基板的一个或多个光伏元件。 在另一个实施例中,本发明提供了一种光伏屋面元件,其包括包括沥青基板的屋顶基板和设置在沥青基板上的多个着色屋顶颗粒,屋顶基板在CIE实验室坐标L *的颜色空间内具有颜色 约20至约20的范围,a *在约-5至约5的范围内,b *在-15至约-5的范围内; 以及固定到屋顶基板上的一个或多个光伏元件。
