    TITLE
    Solar Module
    TECHNICAL FIELD
    The present disclosure relates to solar modules, also referred to as solar panels or photovoltaic modules, and are modules or panels that absorbs the photons of light to thereby convert the energy of light into electricity. The present invention relates in particular to solar panels that have an aesthetic look that allows the solar panels to be included in buildings and other structures in an aesthetic way. A solar panel typically comprises a number of photovoltaic solar cells and is e.g. used as surface covering on buildings and other structures, caravans and other vehicles, signboards, and on boats. The present disclosure also relates to a method for adjusting the look of a solar panel.
    BACKGROUND
    Solar modules are used for providing electric energy at a wide range of locations. In particular, there is an increasing use of solar modules in order to render both residential and industrial buildings more self-supplying with energy. However, also vehicles and boats are more and more often provided with solar modules. When buildings are mentioned in the following, it is intended that the disclosure also includes other structures, as well as vehicles, signboard and boats.
    DK 2017 70811 A1
    Photovoltaic modules have a rather characteristic look due to the visibility of the solar cells embedded in the modules. This might not be desirable in all designs of buildings. However, an architect may desire to design a building in a different color and may therefore reject the installation of photovoltaic modules or solar heaters in order not to negatively affect the design of the building.
    When designing the solar module, it must be decided whether it should be integrated into the building so as to minimize visibility. Or whether the design of the building should be based on a futuristic look, and the solar modules should form the exterior of the building, for example a green facade. Implementing sustainable (green) energy in the building in this way can serve to cement the architect's name in the industry, and the green profile of the building.
    However, due to the fact that conventional solar modules have a rather characteristic look which does not allow them to be freely integrated into the design of the building, the use of solar modules is often declined by the architects and/or the builders because it does not allow for an individual color selection of the part of the building, where these modules have to be provided. There have been some attempts to provide colored solar modules by adding a colored film covering the front face of the solar modules. However, such a colored film results in a significantly reduced efficiency of the modules, and thereby decreases the amount of electricity produced by the modules.
    EP 2 557 603 discloses a photovoltaic module comprising a layer of solar cells and a layer of glass fiber covering the
    DK 2017 70811 A1 surface of the solar cells. The layer of glass fiber serves to strengthen the structure of the photovoltaic module.
    Accordingly, there is a need for providing a solution to the problem of coloring solar panels in such a manner that they maintain a high efficiency, and at the same time provide an aesthetic look.
    SUMMARY
    The present disclosure provides a solution, or at least a partial solution to the problem of coloring solar modules in such a manner that they show a homogeneously colored outer surface or a colored outer surface in a desired pattern.
    Often it is desirable, that the solar modules should show saturated colors and have a homogeneous look from different angles.
    It is desirable that a high degree of flexibility is available when designing the appearance of the solar modules, such that the solar modules can be provided with one or more colors forming, for example, a drawing simulating one or more rows of slates or other roof material, or the logo or name of a company or any other pattern.
    If a single color is used, this color can be provided in the form of a uniform coloring of the entire surface of the module, or the color can be provided in patterned manner, or the color can have areas of more or less intensity. Likewise, if more colors are used, one or more or all of these colors can be provided in a patterned
    DK 2017 70811 A1 manner or have varying intensity over the entire, or part of the, module.
    According to a first aspect there is provided a solar panel having a layered structure, the solar panel comprising:
    a solar cell layer comprising solar cells, the solar cells having an active front side having a first color, a background layer behind the solar cell layer, or surrounding the solar cells, or in front of the solar cell layer and having at least substantially transparent areas covering the active surfaces of the solar cells, the background layer having a second color that is substantially identical or similar to the first color, a translucent coloring layer in front of the solar cell layer, the translucent coloring layer having a uniform third color or a non-uniform color, the third color being different from the first and second colors and the nonuniform color comprising colors different from the first and second colors.
    The active front face of the solar cells can e.g. be blue or black, in various shades. Typically, the first color and hence also the second color are dark colors. Herein, a reference to a first dark color of the solar cells is intended to embrace the color of both polycrystalline and monocrystalline solar cells.
    According to a possible implementation of the first aspect the background layer has a front side and at least the front side of the background layer has the second color.
    DK 2017 70811 A1
    According to a possible implementation of the first aspect the translucent coloring layer comprises transparent or translucent material covering the solar cells of the solar module.
    Such a translucent coloring layer can for example comprise or be made from glass fiber, or glass wool, or fibers made from a polymeric material, or from organic materials such as cotton, or metal wool, and can comprise a woven or non-woven material comprising fibers made from a single material or a mixture of fibers made from any or a mixture of the above materials. It can also be formed by a grid of filaments made from any or a mixture of the above materials.
    According to a possible implementation of the first aspect, the translucent coloring layer is provided in the form of a woven web of glass fiber having a density, for example in a range between 5 and 75 g/m2, or in a range between 15 and 40 g/m2 or approximately 25g/m2.
    According to a further possible implementation of the first aspect, the translucent coloring layer is provided in the form of a glass fiber felt mat having randomly oriented fibers and having a density, for example in a range between 5 and 75 g/m2, or in a range between 15 and 40 g/m2 or approximately 25g/m2.
    According to one possible implementation of the first aspect, the colored layer of glass fiber has visible openings therethrough.
    DK 2017 70811 A1
    The active surface of a solar cell absorbs about 20% of the incoming light, and reflects the remaining about 80%. Part of the light which is being reflected from the active surface of the solar cell will be reflected back thereto by the material comprised in the colored layer which is arranged in front of the active surface of the solar cell. Thereby the amount of light being absorbed by the solar cell can be increased.
    Also with a thin colored layer of glass fiber having visible openings there through the reflection effect will serve to increase the amount of photons/light reaching the solar cells of the solar module.
    According to another possible implementation of the first aspect the translucent coloring layer comprises one or more non-transparent materials such as e.g. fabric, cloth or metal and the translucent coloring layer is provided with substantially evenly distributed openings therein allowing the rays of light to pass therethrough.
    According to another possible implementation of the first aspect the translucent coloring layer has been colored by a coloring agent by spraying, printing or dipping the carrier material, such as e.g. fibers, filaments, web, mesh or grid in a bath containing pigments. If for example metal wool is used, the filaments can be anodized in order to change their color.
    According to another possible implementation of the first aspect the individual wires, threads, strings, fibers or
    DK 2017 70811 A1 filaments of the colored layer are partly or completely covered by the pigments or the coloring of the toner.
    According to another possible implementation of the first aspect the color or colors of the translucent coloring layer are applied by a printing process.
    According to another possible implementation of the first aspect the coloring agent applied in the translucent coloring layer is temperature resistant up to 160°C.
    According to another possible implementation of the first aspect the coloring agent applied to glass fibers is capable of adhering to glass.
    According to another possible implementation of the first aspect a UV protecting layer is applied.
    According to one possible implementation of the first aspect, the coloring agent is applied in the form of a water based glass paint diluted in a thinner, for example alcohol or water, mixed in the ratio of, for example, 1 part paint to 10 part thinner, dependent on the thinner and the desired colorization of the colored layer.
    According to another possible implementation of the first aspect, the solar panel is provided with a dark back-sheet on the back side of the solar module.
    According to another possible implementation of the first aspect a translucent masking layer is provided between the solar cells and the translucent coloring layer. The masking
    DK 2017 70811 A1 layer should have a color which reduces the visibility of the dark colors of the solar cells. If the desired color of the solar panel is a light color, then the masking layer should be white to achieve the best result. However, if the desired color of the solar panel is of a darker color, then the masking layer could be grey or have a dark color, as long as the masking layer is sufficiently hiding the contour of the cells while still being sufficiently transparent in order to allow sufficient light to reach the solar cells. In the following a white masking layer is used as an example. However, it is intended that the masking layer could also have another color or colors.
    According to a possible implementation of the first aspect the translucent masking and the translucent coloring layers are merged into one layer. Thereby the amount of EVA needed to encapsulate the layers can be reduced.
    According to a possible implementation of the first aspect the solar module is provided with an UV blocking layer, protecting the coloring agent and other parts of the solar module from UV-radiation.
    According to a possible implementation of the first aspect the solar module is provided with a front sheet made from a transparent scratch resistant material such as, for example, glass, plexiglass or a scratch resistant foil, in order to protect the module from being damaged when exposed to wind and weather, and cleaning agents/processes.
    These and other aspects will be apparent from the embodiment(s) described below.

    DETAILED DESCRIPTION
    A solar panel, also referred to as a photovoltaic panel, solar module or photovoltaic module, for the generation of electrical power will be described in detail by non—limiting embodiments with reference to the drawings.
    Fig. 1 and 9 show a solar panel according to an embodiment.
    The solar panel is layered and is provided with intermediate transparent layers 2 between other layers to provide adhesion between such other layers. The intermediate transparent layer 2 preferably comprises a polymer material with good transparency and adhesive qualities, such as e.g. Ethylene-Vinyl Acetate (EVA), or other equivalent UV resistant material.
    The solar panel comprises a background layer in the form of a backsheet 4, a solar cells layer 1, a translucent masking layer 5, a translucent coloring layer 3, and a front glass sheet 6. The solar cells, the translucent masking layer 5 and the translucent coloring layer 3 are all encapsulated in EVA. This can be done in a hot laminating process. The translucent masking layer 5 and translucent colored layer 3 can be merged into one layer whereby the amount of EVA needed to encapsulate the layers can be reduced.
    It is also possible to manufacture the solar panel in a cold laminating process using for example silicone encapsulation.
    DK 2017 70811 A1
    The solar cell layer 1 is provided with a plurality of solar cells or strings of solar cells 1 that at least have one active side. The active side of the solar cells have a first color, for example a dark first color.
    The background layer 4 behind the solar cell layer has a front side having a second dark color that is substantially identical or similar to the first dark color of the solar cells. Thus, the deepest layer of the solar panel has a substantially uniform dark color. The uniform dark color facilitates the provision of a uniform or controlled color appearance of the solar panel.
    A dark color is herein defined as a color which includes dark shades of any color including gray and black.
    The translucent masking layer 5 comprises a transparent or translucent material covering the front face of the solar module. This translucent masking layer comprises in an embodiment white colored glass fiber, white colored fabric, white colored metal, white colored ceramics, white colored polymeric fibers, and/or a mixture of different fibers, or any other equivalent material, and serves to reduce the visibility of the solar cells in the module, and gives the module added mechanical strength. When such a translucent white masking layer is used in combination with a dark backsheet, the visibility of the contours of the solar cells can be completely or substantially completely eliminated while maintaining a high efficiency of the solar module. When the desired color of the solar module is white, this white masking layer constitutes the translucent coloring layer
    DK 2017 70811 A1 referred to above. When the desired color of the solar module is any other than white, this translucent white masking layer will constitute an intermediate layer between the solar cells and the translucent coloring layer, and have the effect that the thickness of the translucent coloring layer can be kept at a minimum, such that the efficiency of the solar module is not substantially reduced, while still obtaining the desired coloring of the surface the solar module. When the desired color of the solar module is a darker color, the masking layer could be gray, contain gray pigments or have another non-white color.
    The translucent coloring layer 3 is arranged in front of the active side of the solar panel layer. In fig. 8, the translucent coloring layer 3 is adhered to the solar cell layer 1 by an intermediate layer 2. In the embodiments of fig 8, the masking layer 5 has been left out. If it is desired to produce a solar panel with a dark color, it is not necessary to have both a masking layer 5 and a colored layer 3, but only one dark colored layer in front of the solar cells will be sufficient, both to provide the colorization of the module, and to mask the solar cells below that layer.
    The translucent coloring layer 3 has in an embodiment a uniform third color that is different from the first and second dark colors.
    In another embodiment, the coloring layer has a nonuniform color comprising colors different from the first and second dark colors. In this embodiment, the nonuniform color preferably represents a pattern or an image or the like.
    DK 2017 70811 A1
    In an embodiment, the translucent coloring layer 3 comprises transparent fibers, such as glass fibers or polymer fibers, colored on their outer surface with the third color, preferably by pigments in the third color on the outer surface. The transparent fibers can be arranged as a fabric, mat or any other woven or nonwoven material.
    In an embodiment, the translucent coloring layer is provided in the form of a woven web of glass fiber having a density, for example in a range between 5 and 75 g/m2, or in a range between 15 and 40 g/m2 or approximately 25g/m2.
    In another embodiment, the translucent coloring layer is provided in the form of a glass fiber felt mat having randomly oriented fibers, and having a density of for example in a range between 5 and 75 g/m2, or in a range between 15 and 40 g/m2 or approximately 25g/m2.
    A translucent coloring layer 3 comprising glass fibers and/ or polymer fibers has the effect that the at least partially colored fibers of the translucent coloring layer, due to their at least substantially cylindrical shape, reflect the incoming rays of light in different directions in such a manner that part of the photons/rays of light reflected from one colored fiber may hit another or more colored fibers and thereby eventually be re-reflected or redirected towards the solar cell. Thereby, more light/photons will reach the active surface of the solar cell, even when a relatively thick translucent coloring layer is selected which does not have openings allowing the rays of incoming light to pass directly through the web. Furthermore, the active surface of
    DK 2017 70811 A1 a solar cell absorbs only about 20% of the incoming light, and reflects the remaining about 80%. Part of the light which is being reflected from the active surface of the solar cell will be reflected back thereto by the colored fibers comprised in the colored layer which is arranged in front of the active surface of the solar cell. However, in order to achieve the best energy yield of the solar cells, the translucent coloring layer should be selected such as not to be thicker and/or denser than necessary to provide the needed colorization and/or strength of the solar module.
    In an embodiment, the colored layer of glass fiber has visible openings therethrough. Also with a thin colored layer of glass fiber having visible openings there through the reflection of the rays of incoming light by the colored fibers of the colored layer serve to increase the amount of photons/light reaching the solar cells of the solar module.
    In another embodiment, the translucent coloring layer 3 comprises colored translucent fibers in the third color, preferably by pigments in the translucent fibers in the third color. The translucent fibers can be arranged as a fabric, mat or any other woven or nonwoven material.
    In a further embodiment, the translucent coloring layer 3 comprises filaments that are dyed or coated in the third color, preferably by pigments in the third color in or on the filaments. The coloring layer 3 comprising one or more non-transparent materials such as e.g. fabric, cloth or metal has substantially evenly distributed openings therein allowing the rays of light to pass therethrough. The fabric, cloth or metal may be woven or nonwoven.
    DK 2017 70811 A1
    The relative size of these openings in the coloring layer is balanced between a high energy yield of the solar panel and at the same time reflect the wished color and intensity. This balance may vary depending on e.g. the desired color, the type of dye used and on the type of non-reflective material used and can be determined by simple trial and error.
    In an embodiment, the translucent coloring layer 3 comprises a web in the third color. The web comprises substantially evenly distributed, preferably visible, openings for allowing light to pass therethrough.
    The coloring layer is colored by a coloring agent according to any known process, including spraying, printing or dipping the carrier material, such as e.g. web, mesh or grid in a bath containing pigments.
    The individual wires, threads, strings, fibers or filaments of the colored layer can be partly or completely covered by the pigments or the coloring of the toner, depending on the desired intensity of the color, and upon the desired pattern of coloring.
    When the colors of the colored layer need to have a more complex pattern, such as a logo or any image comprising one or more colors, the color or colors can be applied by a printing process. However, printing can also be used to apply a uniform color to a colored layer.
    DK 2017 70811 A1
    The coloring agent should for heat encapsulation preferably be temperature resisting up to 160°C, this is not necessary for cold encapsulation of the web. The coloring agent should also be able to adhere to the fibers of the colored layer,
    i.e. when a colored layer made from glass fiber is used, the coloring agent should be capable of adhering to glass. For UV sensitive colors an UV protecting layer can be applied in order to protect the coloring agent from ageing or bleaching too quick.
    In one example, the coloring agent is applied to the glass fibers in the form of a water based glass paint diluted in a thinner, for example alcohol or water, mixed in the ratio of, for example, 1 part paint to 10 part thinner, dependent on the thinner and the desired colorization of the colored layer. A glass fiber mat or web is dipped into the water or alcohol paint mixture and dried, and due to the dilution of the paint only a small amount of pigments from the glass paint will adhere to the fibers in the glass fiber mat, creating a very thin layer of pigments, leaving part of the individual fibers uncovered by the coloring pigment.
    In an embodiment, the translucent coloring layer can be penetrated and encapsulated in ethylene-vinyl acetate (EVA) or other equivalent UV resistant material with high transparency, such that the colored layer forms a threedimensional layer that reflects the incoming rays of light and thereby serve to improve the amount of photons/rays reaching the cells as explained above, and thereby serves to maintain a high energy yield of the solar module.
    DK 2017 70811 A1
    In an embodiment, the background layer 4 is made from polyvinylfluorid (such as TEDLAR® available from Atimex® or
    DuPont®) or colored glass, or glass fiber, or glass wool, or any other suitable material.
    In one embodiment, the background layer 4 has the same or a similar color as the solar cells of the solar module. The dark back-sheet serves to reduce the visibility of the contours of the individual cells 1 of the solar module, such that the visibility of the pattern of the solar cells 1 through the colored layer is significantly reduced.
    In an embodiment, the background layer 4 is provided in the form of a woven or non-woven material, for example comprising glass fiber, or glass wool having a dark color sprayed or printed thereon, in a pattern matching the space between the solar cells 1 (as shown in Figs. 4 to 6), such as to reduce the contrast between the solar cells and the areas between and around the solar cells 1. In particular, when the background layer 4 is transparent it can be provided in front of the active surface of the solar cells, such that the printed or sprayed dark patterns are aligned with the spaces between the solar cells, and the transparent areas of the background layer are aligned with the active surfaces of the solar panels. It is also possible to apply the background color on the masking layer 5. The background color can be applied, for example by printing or spraying on the masking layer, preferable on the side of the masking layer facing the solar cells, in a pattern matching the space between and around the solar cells 1.
    DK 2017 70811 A1
    The background layer 4 is in an embodiment in the form of a foil having cut out openings 7 aligned with the light absorbing material of the solar cells, as shown in Figs. 4 to 6. Another possibility is a transparent foil having a dark color sprayed or printed thereon, in a pattern matching the space between the solar cells (as shown in Figs. 4 to 6. B2). The above solutions, including the patterned spraying or painting, and the cutout openings 7, are in particular advantageous for use in combination with double sided solar cells and panels.
    In an embodiment, a translucent white masking layer 5 covers the front face of the solar module and comprises white colored glass fiber, fabric, metal, ceramics, a mixture of different fibers, or any other equivalent material, and also serves to reduce the visibility of the solar cells 1 in the module. When such a translucent white masking layer 5 is used in combination with a dark colored background layer 4, the visibility of the contours of the solar cells 1 can be completely or substantially completely eliminated while maintaining a high efficiency of the solar module. When the desired color of the solar module is white, this translucent white masking layer 5 constitutes the translucent coloring layer 3 referred to above. When the desired color of the solar module is any other than white, this translucent white masking layer 5 will constitute an intermediate layer between the solar cells 1 and the translucent coloring layer 3, and has the effect that the thickness of the translucent coloring layer 3 can be kept at a minimum, such that the efficiency of the solar module is optimized. When the desired color of the solar module is a darker color, the masking layer could be gray or have another non-white color.
    DK 2017 70811 A1
    The second dark color of the background layer 4 serves to reduce the visibility of the contours of the individual solar cells 1 of the solar module, such that the visibility of the pattern of the solar cells 1 through the translucent coloring layer 3 is significantly reduced. The dark backsheet 4 can be black or have any other dark color.
    In order to further reduce the visibility, the ribbons 9 that extended and connect the stream of solar cells 1 are covered by paint or tape 10 having a fourth dark color that is similar or matches the first dark color, in order to minimize the impact of the ribbons 9 on the overall appearance and color of the solar panel, as shown in Fig 7. In Fig. 7 the two ribbons to the left are provided with dark colored tape 10 and the ribbon 9 on the right is not provided with a dark color for illustrating the effect of providing a dark colored tape. The ribbons could also be anodized in order to darken their color.
    Fig. 2 shows a further embodiment comprising a background layer 4, a solar cell layer 1, a translucent white masking layer 5, a translucent color layer 3, a UV blocking layer 11, and a front glass sheet 6, with intermediate layers 2 in between.
    Fig. 8 shows a solar module comprising a solar cell layer 1 and a translucent coloring layer 3 embedded in intermediate layers 2 of EVA. A background layer 4 can be provided as a layer on the back side of the solar cells 1, or in the form of a foil having cut out openings 7 aligned with the light absorbing surfaces of the solar cells, as shown in Figs. 4
    DK 2017 70811 A1 to 6. Furthermore, when the background layer 4 is transparent it can be provided in front of the active surface of the solar cells, such that the printed or sprayed dark patterns are aligned with the spaces between the solar cells, and the transparent areas of the background layer are aligned with the active surfaces of the solar panels. The embodiment of Fig. 8 does not comprise a white masking layer
    5. When the desired color of the solar panel is black, the white masking layer 5 is not necessary and can be left out, as the color black can be achieved by the colored layer 3 only. When the desired color of the solar panel is white, the colored layer 3 can be left out, as the color white can be achieved by the white masking layer 5 only.
    Fig. 10 shows a double sided solar panel with a background layer 4 shown in Fig. 4 to 6 with a dark second color on both sides of the background layer 4.
    Figs. 3 and 11 shows a double sided solar panel essentially identical to the solar panel of figure 10, except that a translucent white masking layer 3 and a front sheet 6 have been added on both sides of the solar panel, together with the required intermediate layers.
