    Description TECHNICAL FIELD The invention relates to a photovoltaic module according to the preamble of claim 1, as well as to a shutter and a method according to the independent claims.
    Background Art [0002] Photovoltaic modules are used in many places today. One possible site for photovoltaic systems is building facades, which is also referred to as BIPV applications, with BIPV standing for "building-integrated photovoltaics".
    Such BIPV applications are not necessarily concerned with the fact that the photovoltaic modules used produce electric current as efficiently as possible. Rather, in the integration of photovoltaic modules in building facades also aesthetic aspects play a crucial role in the approval of construction projects.
    In this context, inter alia, there is a need for photovoltaic modules, which can be integrated into the building facade, without being recognizable as such at first glance, and / or without the structural character of the building in question is too changed ,
    From the prior art is already known to integrate photovoltaic modules in shutters. For example, DE 60 2004 006 316 T2 discloses shutter blades in which photovoltaic modules are integrated. The construction disclosed there, however, has the disadvantage that it consists of a large number of components, is constructed in a generally complicated manner, and moreover is not suitable for permanent power generation, but rather for the temporary drive of the shutter.
    OBJECT OF THE INVENTION It is the object of the invention to remedy or at least mitigate the disadvantages of the aforementioned prior art. In particular, it is the object of the invention to provide a way to integrate photovoltaic modules in building facades, through which the structural character of the building in question is changed as little as possible, and by which a permanent power production is possible. SOLUTION OF THE OBJECT The object is achieved by a photovoltaic module, wherein the photovoltaic module comprises a front side and a rear side, wherein the photovoltaic module is suitable to be integrated into a shutter, the photovoltaic module being suitable for current from light incident on its front side and wherein the photovoltaic module is adapted to generate power from light incident on its backside.
    The solution of the problem is based on the following multi-level knowledge: shutters, in particular pivotable about a vertical axis wing shops, which are typically located right and left of the windows of buildings, typically contribute a considerable part of the structural character of a building and thus both in existing buildings as are often present in new buildings. These shutters are often exposed to strong sunlight and are therefore suitable in principle as installation location for photovoltaic modules. Shutters are particularly well suited as installation locations for photovoltaic modules, as they are often present anyway and can therefore be used ideally as a basis for photovoltaic modules, without changing the appearance of the building too much. In contrast, the appearance of photovoltaic modules, which are integrated into the facade itself, changed significantly stronger. However, in order to ensure electricity production in photovoltaic modules integrated in shutters, the photovoltaic modules must be able to generate power both when the shutters are open and when the shutters are closed. A photovoltaic module according to the invention, which can be integrated in particular in a shutter and can generate current from light incident on the front side as well as from light incident from the rear, thus solves the problem mentioned at the outset.
    In advantageous embodiments, the photovoltaic module comprises a solar cell, wherein the solar cell is advantageously a bifacial solar cell. Preferably, the photovoltaic module comprises a plurality of bifacial solar cells. The advantage of using bifacial solar cells is that the complexity of the photovoltaic module can be greatly reduced because one and the same solar cell can be used to produce electricity both when the shutter is open and closed. Alternatively, however, it is also possible to use a module with solar cells, which are aligned to different sides.
    In advantageous embodiments, the photovoltaic module is at least partially translucent. This has the advantage that even with the shutter closed still a certain amount of residual light penetrates into the building. Namely, typical shutters often include an insert made of struts, through which just a certain amount of residual light is transmitted. An at least partially translucent - or in other words semitransparent - photovoltaic module thus has the advantage that this typical shutter functionality is maintained.
    In advantageous embodiments, the photovoltaic module is colored, wherein preferably the front and / or the back is colored or are, wherein the front and the back are preferably substantially the same color. Such a photovoltaic module has the advantage that it is particularly well adaptable to an existing building facade and / or to an existing or desired type of shutter. In typical embodiments, the front side and / or the back side for this purpose comprises a color layer, for example a green, blue, red, yellow, white or black color layer. The ink layer is preferably at least partially translucent. However, it is also possible that the photovoltaic module is not colored but transparent, for example.
    In advantageous embodiments, the photovoltaic module comprises a light source, preferably an LED, preferably several LEDs.
    In advantageous embodiments, the photovoltaic module comprises a battery.
    In advantageous embodiments, the photovoltaic module comprises a lightning and / or overvoltage protection.
    In advantageous embodiments, the photovoltaic module is suitable for wireless and / or contactless energy transmission.
    A shutter according to the invention comprises a photovoltaic module according to the invention. In this case, the shutter is preferably a wing store, which is preferably suitable to be pivoted about a vertical axis, preferably by 180 degrees.
    In advantageous embodiments, the shutter comprises a first frame, preferably metal frame, which surrounds the photovoltaic module and / or the shutter comprises a second frame, preferably wooden frame, which surrounds the photovoltaic module. In advantageous embodiments, the first frame and / or the second frame is so wide that a surface of the photovoltaic module is at most 80%, advantageously at most 65%, advantageously at most 50% of an area of the entire shutter. A photovoltaic module, which is thus surrounded by a frame and thus is significantly smaller than the entire shutter, has the advantage that it is relatively easy. In particular, a shutter, which is, for example, only 65% filled by a photovoltaic module according to the invention, is significantly lighter than a shutter in which e.g. 95% of its surface is filled by a photovoltaic module according to the invention. This lower weight is advantageous because such a relatively light shutter can be better integrated into an existing building facade, as a heavier, because the risk of breaking out of existing hinges from the building facade is minimized. However, it is also possible that the surface of the photovoltaic module substantially corresponds to the area of the shutter and / or that the shutter is frameless.
    In advantageous embodiments, the shutter comprises a light source and / or a battery. The light source typically comprises one LED, preferably several LEDs. In general, a light source in the shutter has the advantage that a space arranged behind the closed shutter can be supplied with power by the light source when the shutter is closed. The light source is typically arranged at the shutter so that it is suitable when the shutter is closed, to provide a room at the window of the shutter is provided with light. A battery has the advantage that at least part of the electrical energy generated by the photovoltaic module can be temporarily stored in the shutter itself. This battery can then be e.g. be used to operate the light source. However, neither a light source nor a battery are mandatory. Rather, it is also possible to easily connect the photovoltaic module to a building electricity network.
    In advantageous embodiments, the shutter comprises a lightning and / or overvoltage protection. For this purpose, the shutter typically comprises at least one surge arrester and / or a varistor and / or a thyristor. Lightning and / or overvoltage protection has the advantage that damage to the photovoltaic module as a result of direct and especially indirect lightning strikes can be avoided. As indirect lightning strikes here currents and voltages are referred to, which are induced as a result of near lightning currents in the photovoltaic module. Such near lightning currents can flow, for example, by external lightning conductors on the facade or by gutters in the immediate vicinity of the shutters.
    In advantageous embodiments, the shutter is suitable to transmit wirelessly and / or contactless energy to a building power system. In typical embodiments, the shutter for this purpose comprises a sliding contact, which is advantageously suitable for electrically interacting with a suspension of the shutter and / or the shutter comprises a device for contactless energy transmission, for example an inductive energy transmission device. This has the advantage that no cabling is necessary. Alternatively, however, cables can be used.
    In a method according to the invention for renovating a building, an inventive photovoltaic module is inserted into an existing shutter and / or the existing shutter is replaced by a shutter according to the invention.
    DESCRIPTION OF THE FIGURES
    The invention will be described in more detail below with the aid of drawings, in which:
    1 is a schematic front view of a conventional shutter,
    2 shows a schematic front view of a shutter according to the invention,
    3 shows a schematic front view of another inventive shutter, and
    4 shows a schematic sectional view of a photovoltaic module according to the invention.
    DESCRIPTION OF PREFERRED EMBODIMENTS Fig. 1 shows a schematic front view of a conventional shutter L. The shutter L comprises a frame 1, which is typically made of wood, and an inner part 2 comprising a plurality of strips. By unspecified spaces between these strips light can pass. By means of two fasteners 3 (e.g., hinges), the shutter L can be fixed to a building facade.
    FIG. 2 shows a schematic front view of a shutter F according to the invention. The shutter F is very similar to the shutter L shown in FIG. 1, but in the shutter F the interior portion 2 has been replaced by a photovoltaic module P according to the invention. This photovoltaic module P comprises a plurality of solar cells 4. These solar cells 4 are bifacial solar cells, which both light, which falls from the viewer's view of the photovoltaic module P, as well as light, which falls from the Bertachter side facing away from the shutter F on the photovoltaic module P, able to convert into electricity. The photovoltaic module P has an area which corresponds to approximately 52% of a total area of the shutter F.
    FIG. 3 shows a schematic front view of another shutter F according to the invention. The shutter F shown in FIG. 3 essentially corresponds to the shutter F shown in FIG. 2, but the shutter F in FIG. 3 does not comprise a wide wooden frame 1 only a narrow metal frame 1. The surface of the photovoltaic module P is almost as large as the total area of the shutter F - in other words: The photovoltaic module P fills the shutter F completely, except for the narrow, preferably at most 5 cm wide Metal frame 1, which surrounds the photovoltaic module P.
    Fig. 4 shows a schematic sectional view of a photovoltaic module according to the invention P. The photovoltaic module P comprises in its center a plurality of bifacial solar cells 4. Between the bifacial solar cells 4 gaps 5 are arranged so that the photovoltaic module P is at least partially translucent. The solar cells 4 are embedded between a first melt film 7.1 and a second melt film 7.2. On a front side of the photovoltaic module P, a first glass pane 6.1 is arranged, and on a rear side of the photovoltaic module P, a second glass pane 6.2 is arranged. The first glass pane 6.1 comprises on its rear side - ie its side facing the first melting film 7.1 - a first colored printing 8.1. The front of the photovoltaic module P thus appears colored to a viewer - in other words: the front side of the photovoltaic module P is colored. Analogously, the second glass pane 6.2 of the photovoltaic module P comprises a second colored printing 8.2. The colored printing 8.1, 8.2 are shown in Fig. 4 by small horizontal lines. The colored printings 8.1 and 8.2 can be the same color or different colors. The photovoltaic module P shown in Fig. 4 is adapted to generate electric current from light incident on its front side. Moreover, since the solar cells 4 are bifacial solar cells, the photovoltaic module P is capable of generating electric power also from light incident on its backside.
    The invention is not limited to the described embodiments. Rather, the scope of protection is determined by the claims.
