Abstract: We describe a window assembly (100) comprising: a window pane (102) comprising a glass or plastic sheet; and a layer of holographic recording medium (104) attached to said glass or plastic sheet; wherein said layer of holographic recording medium has recorded within the medium a volume hologram (106) configured to direct light incident onto said glass or plastic sheet to propagate within a thickness of said glass or plastic sheet, preferably to a photovoltaic element (120). In embodiments the volume hologram is fabricated by recording a transmission hologram and shrinking the recorded hologram to convert the transmission hologram to an edge-directing hologram configured to direct light in a direction to be totally internally reflected within the window pane, for example at greater than 40°, 50°, 60°, 70°, 75° or 80° to a normal to the surface of the hologram.
Abstract translation: 我们描述了一种窗户组件（100），包括：包括玻璃或塑料片的窗玻璃（102） 以及附接到所述玻璃或塑料片的全息记录介质层（104）; 其中所述全息记录介质层已经在所述介质内记录了体积全息图（106），所述体积全息图被配置为引导入射到所述玻璃或塑料片上的光在所述玻璃或塑料片的厚度内传播，优选地传播到光电元件（120）。 在实施例中，体积全息图是通过记录透射全息图并收缩所记录的全息图来制造的，以将透射全息图转换成边缘定向全息图，该边缘定向全息图被配置为将光引向在窗玻璃内完全内部反射的方向，例如大于 40°，50°，60°，70°，75°或80°，与全息图表面垂直。
