Abstract

The object of the invention is to functionally improve a profiled glass sheet. The invention relates to a profiled glass sheet with photovoltaic function (10), comprising a profiled glass sheet (11), which has at least one web (12) with an inner web surface (14) and an outer web surface (16) and at least one flange (18) with an inner flange surface (20) and an outer flange surface (22 ), and a photovoltaically effective PV layer system (24) which is applied to one or more of the inner surfaces (14, 20) and/or outer surfaces (16, 22) of the profiled glass sheet (10).

Description

The invention relates to a multifunctional profiled glass sheet that has at least one web and at least one flange. The invention further relates to a profiled glass arrangement comprising at least one row of profiled glass sheets arranged next to one another, which include such profiled glass sheets. The invention also relates to a kit-of-parts and a manufacturing process for producing multifunctional profiled glass sheets.

Profiled glass sheets with dimensionally stable, translucent components fitted therein, such as further glass plates for mechanical stabilization or translucent capillary devices for thermal insulation, as well as profiled glass arrangements comprising such profiled glass sheets are, for example, from the EP 1 058 760 B1 or EP 0 742 34 B1 known.

Profiled glass sheets are formed in particular by glass profiles. In particular, U-glass profiles with a web and two flanges, which together form a U-profile, or L-profiles with a web and a flange on the side come into consideration. They are assembled into profiled glass arrangements for glazing and buildings.

The profiled glass sheets can be assembled in a single layer in a single row of profiled glass sheets arranged next to one another and connected to one another. The profiled glass sheets and the profiled glass arrangements then preferably have recesses that are open on one side and are formed by the web and a flange (when combining L-glass profiles) or two flanges (when combining U-glass profiles).

The profiled glass sheets can still be put together in a double-layered manner. In a double-shell design, a first row of profiled glass sheets and, in parallel, a second row of profiled glass sheets are joined together to form a two-row profiled glass arrangement, with the flanges of the first row and the flanges of the second row preferably facing each other. In the case of U-shaped profiled glass sheets, the flanges can be arranged butt-butting together or nested one inside the other. In both configurations, cavities are created between the two rows of profiled glass sheets, which are open on the end faces of the profiled glass sheets.

For a three-shell or multi-shell design of the profiled glass arrangement, further rows of profiled glass sheets can be placed on a double-shelled profiled glass arrangement, which creates additional cavities or open recesses depending on the orientation of the flanges of the profiled glass sheets of this bottle.

From the EP 0 742 324 B1 It is known to provide transparent thermal insulation devices on the inside of the webs. For example, capillary packings, capillary plates, capillary tube packings or glass ball packings are arranged for this purpose.

The further state of the art is referred to DE 36 16 332 A1 , the DE 103 06 529 A1 and the WO 2014/097 326 A1 referred. Accordingly, multifunctional assemblies are known that contain glass elements and photovoltaic elements. The construction, handling and connection of the photovoltaic elements are complicated, and special measures are necessary to protect the photovoltaic elements.

The invention has set itself the task of functionally improving profiled glass sheets and profiled glass arrangements.

To solve this problem, the invention proposes a profiled glass sheet according to claim 1.

Advantageous embodiments of the invention are the subject of the subclaims.

According to a first aspect, the invention creates a profiled glass sheet with a photovoltaic function, comprising a profiled glass sheet which comprises at least one web with an inner surface of the web and an outer surface of the web and at least one flange with an inner flange surface and an outer flange surface, and a photovoltaically effective PV layer system which is on one or more of the inner surfaces and/or or external surfaces of the profiled glass sheet is applied.

Preferred embodiments of the invention relate to profiled glass with laminated PV cells or with films onto which PV cells are printed. Preferably, profiled glass is created with PV modules and/or PV films.

It is preferred that the PV layer system has at least one solar cell selected from the group including an organic solar cell, a hybrid solar cell, a dye solar cell and a thin film solar cell.

It is preferred that the PV layer system has a flexible PV film or solar film that is glued to the profiled glass sheet.

The PV layer system is preferably semi-transparent. The PV layer system is preferably manufactured on the basis of polymer-based, organic semiconductors. Fine layers of ink are preferably applied to a thin and elastic film or directly to the profiled glass sheet using a coating process.

According to a further aspect, the invention creates a method for producing a profiled glass sheet with photovoltaic function comprising:

• Providing an L or U glass profile that includes a web with an inner web surface and an outer web surface and at least one flange with an inner flange surface and an outer flange surface, and
  1. a) printing an organic solar cell on the inner surface of the bar or

Profiled building glass, which was initially used as a cost-effective economical solution in simple industrial and commercial buildings in the first decades after the Second World War, is now used as U-glass even in the highest quality architectural projects such as museums, due to its product refinement, quality, clear shapes and technical diversity. Theaters, hospitals, shopping centers, sports stadiums as well as company and office buildings, often used in a design-oriented manner all over the world.

According to one embodiment, U-glass is used as a profile building glass sheet. The U-glass can be provided in large lengths, e.g. up to 7 m, in thermally toughened finish as safety glass, with and without colored enamel or sandblasting. There are also a variety of possible glass surfaces to meet the constant desire for attractive aesthetic solutions and stylish design. A point-supported profile glass facade fastened using a hole is also possible as a profile building glass arrangement.

The profiled glass sheet can have a maximum glass length of preferably up to 700 cm. The visible width of the profiled glass sheet, which corresponds to the web width b, is as large as technically and statically possible. It can be, for example, about 200 to 600 mm, preferably about 300 to 500 mm. A special web width is around 400 mm. The aim of using large web widths is to maximize the visible width and minimize the sealant joints so that maximum daylight entry is achieved inside. The flange height h can preferably be in the range from 30 to 100 mm and is, for example, 60 mm. The glass thickness d is preferably 5 to 10 mm and is, for example, 7 mm.

The permissible lower limit for the glass thickness d depends on the stability of the glass used. External thermal toughening leads to a significant increase in glass strength and allows the use of thinner glass in more demanding situations, such as when exposed to strong wind loads.

Thermal toughening enables a 5-fold increase in profile glass, which is already strong due to its U-profile, and makes it possible, for example, to successfully use a 400 mm wide and 7 m long profile glass sheet.

• • Natürliches Tageslicht
• • Hohe Lichttransmission
• • Große Einbaulängen für Fassaden
• • Hervorragender Schallschutz
• • Einschalige-, doppelschalige- und mehrschalige Verglasungen, vertikal und horizontal
• • Gekrümmte Verglasung z.B. Rundverglasungen
• • Schnelle und einfache Wartung und Ersatz

Due to its L or U shape, profiled glass can withstand excellent loads in contrast to flat glass panes and can therefore be installed in very considerable lengths (up to 7m depending on wind load) without crossbars. Profiled glass has such a high static strength that there is no need for side bars. The result is a facade that offers a maximum of glass and uses a minimum of frame profiles. Further advantages of preferred embodiments are:

• • Natural daylight
• • High light transmission
• • Large installation lengths for facades
• • Excellent sound insulation
• • Single-skin, double-shell and multi-skin glazing, vertical and horizontal
• • Curved glazing e.g. round glazing
• • Quick and easy maintenance and replacement

Because of this, a very high proportion of glass can be used in a building with profiled glass sheets. Thanks to the preferred embodiments of the invention, a large proportion of the building can now also be used to generate electricity.

The particular advantages are that the profiled glass sheet itself is used as a substrate for applying a PV layer system. This creates a very resilient element. The PV layer system is optimally protected. This is of course particularly true if this is applied to one of the insides or to an outside of a profiled glass sheet used further inside in a profiled glass arrangement or with its outside oriented towards the interior of the building.

Sensitive layers can also be used for the PV layer systems. Due to the large glass surfaces available, high electricity production is achieved even with layers with relatively low photovoltaic efficiency. This means that inexpensive PV layer systems, such as organic solar cells, hybrid solar cells or solar films (PV films) can also be used.

Thermally pre-stressed profiled glass sheets have an extraordinarily high temperature resistance. The PV layer system can therefore also be applied using thermal application processes.

In inexpensive variants, the PV layer system can be provided as a flexible film. For this purpose, the PV layer system can be used, for example, as a solar film, with thin-film solar cells or with color fabric solar cells are provided. The application can be done by squeegeeing (holding in place by excluding air), laminating or gluing. Thermal connection techniques are also easily possible - especially with thermally pre-stressed profiled glass sheets - without there being an increased risk of breakage in the profiled glass sheet.

In particularly preferred embodiments, the PV layer system is produced directly on the profiled glass sheet, in particular by printing or by other deposition processes.

Examples of embodiments are explained in more detail below using the accompanying drawings. It shows:

• 1 a cross-sectional view of a profile building glass sheet with a U-profile and a PV layer system applied therein;
• 2 a single-shell profiled glass arrangement made of four profiled glass sheets, as shown in 1 are shown, according to a first preferred embodiment;
• 3 a double-shell profiled glass arrangement made of eight profiled glass sheets, as shown in 1 are shown, according to a second preferred embodiment;

• 1 shows a cross-sectional view of a profiled glass sheet with photovoltaic function 10 with a U-profile with a photovoltaically effective PV layer system 24 applied therein, for example glued, doctored or printed.

The U-profile glass sheet comprises a web 12 with an inner web surface 14 and an outer web surface 16 as well as two flanges 18 with an inner flange surface 20 and an outer flange surface 22. On the web inner surface 14 is a PV layer system 24 in the form of a PV film, such as the “ASCA® film” from ASCA ^® by Armor glued or laminated. An equivalent design based on a profiled glass sheet with an L-profile, which also includes a web and an inner web surface for fastening the PV layer system 24, is also possible.

The PV film “ASCAO-film” has a mass of 450 g/m2 +/-50g/m2, is bendable and easy to roll up and is semi-transparent (up to 20% or more light transmission). It is available in different colors and in different dimensions. An electrical output of up to 40 Wp/m2 can be achieved and can be operated in the temperature range -20° to +65° C.

The profiled glass sheet 10, 11 has a web width b of, for example, approximately 200 to 600 mm, preferably approximately 300 to 500 mm, here approximately 400 mm. The profiled glass sheet 10, 11 has a flange height h of, for example, approximately 30 to 100 mm, here approximately 60 mm. The glass thickness d is preferably about 5 to 10 mm and here is about 7 mm. The glass thickness d depends on the desired stability of the profiled glass sheet and can be reduced with thermally toughened glass. The profiled glass sheet 10, 11 can have a maximum glass length of preferably up to 700 cm (not visible in cross section).

The profile glass sheets 10, 11 are manufactured and designed as described in the company publication “Lamberts LINIT - Technical Introduction to U-Glas”, 6th edition, print reference Lamberts/Linit TE 6 de/012009 from September 2012 and/or in the general building regulations Approval No. Z-70.4-44 dated December 21, 2012 is described and shown. These two documents are incorporated herein by reference and form parts of the disclosure herein.

The profile glass sheet 10, 11 are formed, for example, from natural glass profiles, ornamental glass profiles, profile glasses with heat protection coating, sandblasted profile glasses, UV protection profile glasses, toughened profile glasses and / or prism profile glasses. The profile glass 10, 11 can be provided with a prism structure on its outer web surface 16.

The profile building glass sheet 10, 11 according to 1 can be assembled as a single-shell 110 or double-shell 120, 130 to form a profiled glass arrangement 100. When assembled in a double-shell profile glass arrangement 100, cavities 140 are created within the arrangement 100 for receiving the heat-insulating mat 24 made of a flexible, fibrous polymer composite material.

2 shows a single-shell profiled glass arrangement 100 made from a single row 110 of profiled glass sheets with photovoltaic function 10. The side below the profiled glass arrangement 100 corresponds to the outside 150, the side above the profiled glass arrangement 100 corresponds to the side of the building 160. The flanges 18 point towards the building. The flanges 18 can also point outwards in the opposite arrangement. In addition, the profiled glass sheets with heat-insulating properties 10 can be lined up in a sheet pile wall or hooked together. The attachment of profile building glass sheets with heat-insulating properties 10 to a building takes place, for example, via aluminum frame profiles (not shown) on the end faces of the profiled glass sheets.

In the 3 The embodiment shown relates to a double-shell arrangement of profiled glass sheets 10, 11, with only the profiled glass sheets arranged on the outside 150 being profiled glass sheets with photovoltaic function 10.

Alternatively or additionally, the profile building glass sheets on the building side 160 can be equipped with the PV layer system 24. In this double-shell design, the profiled glass sheets 10, 11 are each arranged butt-butting against one another via their flanges (flange-to-flange arrangement), whereby cavities 140 are formed. All profiled glass sheets 10, 11 are connected via profile strips 180, such as cushion profiles, which have a total of four grooves into which the flanges of adjacent professional glass sheets 10, 11 of both shells 120, 130 can be inserted. For further details on connecting the profiled glass sheets 10, 11 with such profile strips 180, see the document EP 0 742 324 B1 and the company publication “Lamberts LINIT - Technical Introduction to U-Glas” mentioned above.

In the 4 The embodiment shown relates to a double-shell arrangement of profiled glass sheets 10, 11, with only the profiled glass sheets arranged on the building side 160 being profiled glass sheets with photovoltaic function 10. It is also possible for the profiled glass sheets on the outside to be 150 profiled glass sheets with photovoltaic function 10. The flanges of the profiled glass sheets 10, 11 interlock with one another (flange joints in pairs) and thus form cavities 140 for receiving the heat-insulating mat 24. The profiled glass sheets are connected via profile strips 180. The shells formed from the two rows 120, 130 of profiled glass sheets are also included Sealed with silicone 190. For further details on this type of connection of the profiled glass sheets 10, 11, see the document EP 0 742 324 B1 and the company publication “Lamberts LINIT - Technical Introduction to U-Glas” mentioned above.

In alternative versions, the PV layer system 24 is printed directly onto the profiled glass sheet in the form of organic solar cells; see the reference [4] for more details. Hybrid solar cells, thin-film solar cells or Grätzel cells can also be used to form the PV layer system 24.

Due to the open structure of the profiled glass sheets with photovoltaic structure 10, the electrodes of the PV layer system 24 can easily be electrically connected. In addition, thermal insulation, for example a TWD (not shown), can be applied further inside on the PV layer system 24 in the profiled glass sheet.
