These are in particular a) a reduced penetration of the radiation into an interior space, b) a reduced heat input at high sun position, c) the light guidance of the natural light at low sun position, e.g. to the ceilings of rooms, d) a view of the exterior of a building without glare, e) the generation of electrical energy by means of the photovoltaics (PV) integrated into the new window elements, 0 the concentration of the interlacing light on the individual photovoltaic cells and last but not least g) an appealing architectural effect, ie a homogeneous, planar appearance despite the three-dimensional topography on one side or between the panes. In conventional applications, windows and glass facades are intended to allow daylight into interiors, provide thermal insulation, weather and sound insulation, and allow for a clear view, especially from the inside to the outside. The incident light should also cause no glare and / or overheating of the interiors. According to the state of the art of structural engineering, in most cases single-pane glasses, multi-pane glass composites or glass-glass laminates are installed in a multi-pane laminated gas window in the façade. Also embodiments as sunscreens, e.g. By means of infrared-blocking coating are possible, these fixtures usually bring high light inputs, but low glare protection. This leads at least in summer to overheating of the interiors and to an often perceived as unpleasant Blendwirkurg, which is not desirable, for example, at computer workstations. All other known shading elements, e.g. Exterior blinds, shading panels, indoor blinds or interior blinds must be produced and installed in addition to the finished windows or façade elements in order to provide glare protection. 30/03/2012 12:51 Nr .: R289 P.004 / 024 30/03/2012 12:52 WILDHACK JELLINEK »53424535 NUM538 D05 30/03/2012 12:52 WILDHACK JELLINEK» 53424535 NUM538 D05 ·· «« · # IS ' Floating systems, such as e.g. Exterior or interior blinds are also mounted in addition to the finished windows or facade elements. They usually allow variable switching between light control or shading or glare protection. There are also photovoltaic window or facade elements as shading elements or as antiglare conventionally available and common, which actively generate electrical energy. These known building integrated photovoltaic elements have partial transparency, and are based e.g. on crystalline technologies between, for example, 15 cm * 15 cm photovoltaic cells and / or holes in the cells, or semi-transparency between about 5 mm * 1 cm thin-film cells. A shading dependent on the position of the sun is also achieved according to the prior art, for example, by mounting two glass panes provided with horizontal photovoltaic strips at a small distance and offset from one another, cf. Sun protection device according to DE 10 2007 013 331 A1 of 2008. The advantages and disadvantages of the relevant solutions of the prior art are in particular the following: If only a conventional sunshade is mounted, it is usually necessary to pull a shading element from top to bottom, such as ζ, Β. Exterior blinds, shading panels, interior blinds or interior blinds, and in the case of glare protection, the light input over the entire window or facade area is greatly reduced and it is then usually an additional interior lighting necessary. This is in particular energy-technically not profitable. Uchtlenkende systems usually allow variable between light control or shading or glare switch, but must also be mounted in addition, which means a considerable material and cost. Photovoltaic elements: Previously known photovoltaic facade elements allow in addition to the production of electricity a constant shading effect and thus a glare protection and quite a certain view to the outside. They offer homogeneous shading or semitransparency or a high-contrast shadow pattern, ie a partial transperency. The disadvantage is that the shading effect and thus the glare protection and the light entry regardless of the season and sun position always remains the same. Although these known systems actively generate energy, but by the angle to the horizon of 90 *. that is, as a result of the vertical orientation of the light input to the photovoltaic cells is only about 70% of the maximum possible light input. 30/03/2012 12:52 No .: R289 P.005 / 024 30/03/2012 12:52 UIILDHACK JELL1NEK * 53424535 NUM538 G> 06 »· • ψ ···· • ** s» «* ψ · • ♦ · * • Ψ ψ · • t · 1 ··:: 4 · e ** s · · 4 * «· * * •» ·· »· • V •« * ·· * · An ideal orientation is only possible when using photovoltaic shading panels. However, these must be mounted in turn. In a known photovoltaic system, there is a system solution with two glass panes with strip-shaped photovoltaic cells. The distance of the glass panes, the distance of the photovoltaic strips from each other and their width determine the angles under which review, light or glare. Disadvantage of this system has become known that in order to achieve a glare protection, the light must be blocked from above obliquely. Thus, a light entry in the sense of a light control to the ceiling and thus in the depth of the room is not possible. Furthermore, depending on the position of the beholder, in the depth of the room, at the window, sitting or standing, a different and always only partial view is possible, and the sky is not visible at all. Old outdoor systems not completely integrated in the window or façade surface, e.g. Blinds, roller blinds, shading panels, photovoltaic panels udgl. can at high wind speeds, such as ζ, Β. from about 100km / h, not or only conditionally used. In addition, old systems that are not completely integrated into the window or façade surface require a substantial amount of installation space, ie additional costs and additional costs, due to the fact that two systems, e.g. Windows and shading elements, with separate functionalities, in place of a window or façade-integrated multifunctional system, which saves on "sublimation costs". allows to be used.

In a two-pane laminate, the patterned photovoltaically active side may cover the inside of an outer pane according to the 'superstrate geometry'. or the outwardly facing side of an inner pane according to the " substrate geometry " form. In a multi-pane composite, the structured thin-film photovoltaic window or façade element is installed as a completely outer pane or laminate. In this case, the structured, photovoltaically active disk can also be found in " Superstrate geometry " or " substrate geometry " to be built in.

The resulting photovoltaic " semi-finished product " is then further processed in a conventional manner, as is customary in window and facade construction, and installed in facades or in prefabricated façade elements. The production of the photovoltaic disk element can of course also be done in any other way, which leads to a corresponding surface structuring of the substrate or Superstrat · material and thus the PV coating. 2 B. For example, glass prisms or similar geometrical structures or structures may be applied to existing double-sided smooth glass or other substrates, e.g. be glued, and be applied to the photovoltaically active layers on their faces, but this requires much more effort It should also be mentioned that other geometrically arranged geometrically arranged structures are also suitable as strip-shaped, parallel arranged prisms for the surface structuring, such as e.g. Raster of pyramids.

When Zweischibenlaminat the structured glass or the module thus formed, which carries the photovoltaic cells, as a semi-finished with a second transparency, in particular glass, laminated. In the multi-pane laminated safety glass window composite, the surface-structured glass carrying the photovoltaic cells is prefabricated as a semifinished product with a second glass pane and then installed in the multi-pane composite, or installed directly as a semi-finished product in the production of the multi-pane laminated safety glass window composite , In the case of a two-pane laminate, the laminate is prefabricated as an outer pane in a window, ie as a multi-pane laminated safety glass window composite, or installed on its own as fixed glazing in the façade on site. In the multi-pane laminated safety glass window composite, the structured glass carrying the photovoltaic cells is prefabricated as a semi-finished product in a composite multi-pane safety glass composite window system. In the facade then the whole composite is installed on site. The dimensions define the electrical parameters of the solar cells and of the solar module and thus of the structured dwarf photovoltaic facade element. i.e. photovoltaic module. In order for a structured thin-film photovoltaic facade cladding, i. a photovoltaic module that can adjust the electrical characteristics, as in the simultaneously submitted Austrian Patent application A ..... / 2012, in each case a plurality of cells connected in series Blocks are combined, which can then be connected in parallel, for example, in the module edge area. This increases the rated current while reducing the nominal voltage. The process of forming these blocks is described in detail in the aforementioned Austrian patent application. The new, structured thin-film photovoltaic window or facade element, ie the photovoltaic module, can be used in facades with various other applications and / or properties. In the case of prismatic structure surfaces, these are achieved by selecting the different values for the prism edge angles α and, in particular, for their partial angles β and p, for the variables hd and Ib, the most important of which are already mentioned above: Further applications are possible with the new PV window and façade elements: 30/03/2012 12:54 No .: R289 P, 010/024 30/03/2012 12:52 WILDHACK JELLINEK - > 53424535 NUM538 Cll * · · 0 I ·· ¢: For example, the structured thin-film photovoltailc façade element, ie the photovoltaic module, can also be used in various other types of applications, except in facades: Apart from the cases described above, it can also be (a) as a spilling roof element, for example with β * y, or also with β> γ see FIG. 6a, in the east-west orientation of the lines, the microstructure of a Shed roofs - with the advantage of interconnecting or receiving light depending on the position of the sun and always also directing diffuse light from the sky to the interior of the building from the north, or (b) being used as an open space module, eg if ß > γ, b »d - with the advantage that even with a little inclined elevation and thus reduced land factors, the optimal orientation can be achieved to the south, i. be used with respect to conventional systems increased area occupation density, for which reference is made to Fig. 6b. As an alternative to a transparent substrate, an opaque carrier material can serve as a substrate. The functionalities that affect the Lichtdurchlaes, then of course fall away. However, all other relevant properties or criteria, ie angles, shading and light concentration are retained.

The photovoltaic substrate 1 shown in Figures 1 and 2 has a structured, i. surface 0 formed with three-dimensional regular bumps in the form of parallel elongated triangular prisms, and consists of " superstrat structure " typically made of a low-iron solar glass of total thickness D, but may also be an opaque metal foil, a semiconductor material, a ceramic or a plastic material in the case of the substrate geometry. The surface structuring is carried out in an ideal and moderately easy to manufacture way by straight-line, triangular in cross-section, usually prismatic elevations. The height hd and width b of the prismatic protrusions 10 have a dimension in the range of mm to cm. Preferably, the length L is equal to the width B of the PV module and is, for example, typically 50 cm for small open space modules, 70 cm for windows or 100 cm and more for large open space modules or in particular facade elements. The number of bumps times their width Ib corresponds to the longitudinal dimension L of the module, typically about 1 to 2 m for open space applications and up to 3 m for windows and e.g. storey-high facade elements. The prism edge angle α, which the legs of the triangular tip or the prism faces assume at the free prism edge, corresponds to the sum of the partial angles β, γ of the two sides or the distance Ib respectively relative to the height hd of the prism cross-section triangle. The angle α is typically 90 ° or near 906. When used in different installation situations of the new window and façade element, however, the angle can vary between 70 and 110 *.

The respective outer pane 2 shows with its smooth surface 20 to the light incidence side or to the influence of weather, while the disc 4 points with its smooth surface 40 inwards. Furthermore, the partial area widths of the triangular prisms 45 and 25 are designated 41, 42 (FIG. 3a) and 21, 22 (FIG. 3b). The ridge angle a of the prisms 45, 25 is divided by the vertical V on the surfaces 40 and 20 into the two partial angles 0 and γ. The base length of the prisms 45, 25 is I, the part length lb associated with the tall angle γ and their height hd. Further, the directions -R * and -R1 indicate the directions of the reflected light, and the current-supplying single elements are denoted by 5.11. FIGS. 4a, 4b, 4c show - with otherwise constant Reference numerals - the basic operation of the new structured thin-film photovoltaic window or facade element. In this case, the variant was selected according to FIG. 3a (Substnatgeometrie) and neglected the beam path through a front glass smooth on both sides. The passage through this disc leads according to the laws of refraction only to a parallel displacement of the incoming light rays. With a full illumination of the facade by the sun, this has no effect on the functioning of the product proposed according to the invention. The passage through the laminating film - that is to say through the film which structurally connects the two glasses - results in a more or less large refraction of light depending on the refractive index. Depending on the refractive index, the angles β and v at the prismatic ridges or edges 12 must be adapted to it in the case of the specific product. The degree of shading of the element and the transparency component can be determined by selecting the angles β and γ and the lengths 11, I2 of the triangle sides or width of the prism surface strips.
