    Abstract: The present disclosure provides a window for a building or structure. The window comprises first and second panels which have major surfaces and are at least largely transmissive for visible light. The second panel has major surfaces which are smaller than the major surfaces of the first panel. Further, the second panel is positioned parallel to the first panel such that the second panel is within a projection of the circumference of the first panel in a direction along the surface normal of the first panel. The first and second panels are laminated together. The first and second panels are arranged such that the first panel has a border region which extend beyond the circumference of the second panel and the laminated first and second panels can be supported at the border region of the first panel.

    Abstract: Methods of producing a graphic mesh for a solar module are described in which mesh parameters such as warp fiber thickness, weft fiber thickness, and open area size are determined to meet a target energetic efficiency and a chromatic effectiveness. In some embodiments, chromatic effectiveness is based on mesh count, where the mesh count is set according to a distance at which the mesh will be viewed when assembled into the solar module. The mesh has a plurality of warp fibers having the warp fiber thickness and a plurality of weft fibers having the weft fiber thickness, that are interlaced to form a plurality of mesh unit cells. A graphic appearance is printed into the mesh using a coloring substance, where the coloring substance is absorbed by the fiber material to form the graphic mesh.

    Abstract: A polymer composite for use as a solar cell encapsulant is defined by a thin film having a first side and an opposing second side and at least one optical structure formed in the film. The least one optical structure includes one or more waveguide formed by a core of a high-refractive index polymer, such as an acrylate and a cladding of a low refractive index polymer, such as a silicone. In a preferred embodiment, two intersecting waveguide arrays are defined, each having waveguides disposed at equal and opposite angles in relation to a normal of a surface of the film. The polymer composite further includes at least one light conversion material that is capable of upconverting and/or downconverting UV and/or IR portions of light entering the film into visible light.
