Hereinafter, a photovoltaic exterior panel and a manufacturing method of the photovoltaic exterior panel according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

(Embodiment 1-1) The present invention relates to a photovoltaic exterior panel, which is exposed to the outside, transmits light, and has a concavo-convex surface 110 formed on the front surface, the cover glass 100, the cover glass 100 ) and includes a solar panel 200 including a solar cell installed on the rear surface of the cover glass 100 and generating electric power by receiving sunlight transmitted from the cover glass 100.

(Example 1-2) The present invention relates to a photovoltaic exterior panel, and in Example 1-1, the cover glass 100 is formed of low iron glass.

(Example 1-3) The present invention relates to a photovoltaic exterior panel. In Example 1-1, the refractive index of the cover glass 100 is 1.6 or less.

(Example 1-4) The present invention relates to a photovoltaic exterior panel, and in Example 1-1, the gloss value of the front surface of the cover glass 100 is 3 to 12.

The present invention relates to an exterior photovoltaic panel including a cover glass 100, and an uneven surface 110 is formed on the front surface of the cover glass 100. Hereinafter, a direction in which light is incident on the cover glass 100 is referred to as front/front, and a surface or direction through which light is transmitted through the cover glass 100 is referred to as rear/rear.

The concavo-convex surface 110 is not a smooth flat surface of the front surface of the cover glass 100, but an irregular surface formed with concavo-convex surfaces. This increases the self-cleaning ability of the cover glass 100 itself and at the same time prevents light from being reflected from the front surface of the cover glass 100, that is, the front surface of the cover glass 100 is treated with anti-glare. It shows no reflection (matte effect).

More specifically, since the solar power generation exterior panel according to the present invention is mainly used as an exterior material of a building, fine dust, acid rain, and various contaminants may be adsorbed on the front surface of the cover glass 100 when exposed to the outside of the building for a long time. can The photovoltaic exterior panel according to the present invention can induce contaminants adsorbed through the concave-convex surface 110 formed on the front surface of the cover glass 100 to be naturally removed when it rains, snows, or winds. there is. This is because the protrusions formed on the concave-convex surface 110 destroy the surface tension of a liquid such as water caused by rain or snow, thereby improving the flowability of the liquid on the surface of the cover glass 100 . That is, the exterior photovoltaic panel according to the present invention can improve self-cleaning capability through the uneven surface 110 formed on the front surface of the cover glass 100 .

The cover glass 100 is preferably transparent glass or low-iron glass to satisfy physical properties such as excellent light transmittance and durability. Low-iron glass is a glass in which the iron content is reduced to remove the green color. General glass has a slight green color due to the iron content contained therein. Considering the solar panel 200 disposed behind the cover glass 100 and transparency, it is more preferable that the cover glass 100 be a low iron glass from which green light is removed.

The cover glass 100 may be made of tempered glass. Tempered glass is divided into fully tempered glass and semi-tempered glass according to the compressive stress. In the case of fully tempered glass, plate glass is heated to 720 degrees Celsius and then rapidly cooled. The standard compressive stress of fully tempered glass is 69 mpa (10000 psi), which is 4 to 5 times higher than normal plate glass. Since fully tempered glass has a higher strength than other glass, it has the advantage of being less damaged even in environments with strong winds such as typhoons or foreign substances flying in from the outside.

Semi-tempered glass, also called double-strengthened glass, refers to glass manufactured by heating ordinary glass below its softening point (600 degrees Celsius) and then cooling it more slowly than tempered glass with cold air. The surface compressive stress of semi-tempered glass is about 24Mpa (3500psi) to 52Mpa (7500psi), which is 2 to 3 times higher in strength than general glass. Semi-tempered glass has a low risk of breaking glass when broken, so it is widely used in high-rise parts of buildings or exteriors.

The cover glass 100 should have high transmittance compared to general glass. That is, this is because the power generation efficiency of the solar panel 200 located at the rear is increased only when the transmittance of the cover glass 100 is high. Therefore, in the present invention, it is preferable that the refractive index of the cover glass 100 is 1.6 or less in order to ensure transmittance of the cover glass 100 to a certain level or higher.

The front gloss value of the cover glass 100 is in the range of 3 to 12. Gloss refers to a smooth state of an etched glass surface, and is a numerical value that affects gloss and light transmittance. Gloss is a value whose value changes depending on the surface shape of the protrusion during etching. The higher the gloss value, the better the transmittance, and the lower the gloss value, the lower the transmittance in proportion.

(Example 2-1) The present invention relates to a photovoltaic exterior panel, and in Example 1-1, the back sheet 300 installed on the rear surface of the solar panel 200, the cover glass 100 ), and a frame 400 installed to surround the outside of the solar panel 200 and the back sheet 300.

(Embodiment 2-2) The present invention relates to a photovoltaic exterior panel. In Embodiment 2-1, the frame 400 includes a front frame member 410 and a rear frame member 420 assembled together. Including, the cover glass 100 and the solar panel 200 are disposed between the front frame member 410 and the rear frame member 420.

(Embodiment 2-3) The present invention relates to a photovoltaic exterior panel. In Embodiment 2-2, at least a part of the front end of the front frame member 410 extends inwardly, and the rear frame member ( 420), at least a part of the rear end extends inward.

The back sheet 300 may be a kind of support for forming an electrical connection required for the solar panel 200 while supporting the solar panel 200 in a plate or film shape. The back sheet 300 may be formed of a conductor or a non-conductor as needed. Materials capable of forming the back sheet 300 may include poly ethylene terephthalate (PET), poly vinyl fluoride (PVF), glass, and the like.

The cover glass 100, the solar panel 200, and the back sheet 300 may be coupled to each other or attached to each other. However, the present invention does not limit the method in which the cover glass 100, the solar panel 200, and the back sheet 300 are bound to each other to either combination or attachment, and each method may be combined with each other.

Even if the cover glass 100, the solar panel 200, and the back sheet 300 are attached or coupled to each other, since each is a different member, the outer boundary of the combination may be the boundary of each member, and the completed sunlight It is not easy to handle power generation exterior panels. For this purpose, the frame 400 is bonded so as to surround the outside of the cover glass 100 , the solar panel 200 and the back sheet 300 . The frame 400 itself may be integrally formed, but may be divided into a front frame member 410 and a rear frame member 420 assembled together. The front frame member 410 and the rear frame member 420 are not simply an integrated frame 400 divided into two, but a part of the front end of the front frame member 410 extends inwardly to form the cover glass 100. A portion that faces the front surface is formed, and a part of the rear end of the rear frame member 420 extends inwardly to form a portion that faces the rear surface of the back seat 300. In this way, a part of the front frame member 410 comes into contact with and wraps a part of the front surface of the cover glass 100, and a part of the rear frame member 420 comes into contact with and wraps a part of the rear surface of the back seat 300. , The cover glass 100, the solar panel 200, and the bonding strength of the back sheet 300 is increased, there is an effect that can provide a more robust solar power generation exterior panel.

The front frame member 410 and the rear frame member 420 are bonded to each other in such a way that portions of the side surfaces overlap each other and an adhesive is applied between the overlapping portions. There may be examples. However, the present invention is not limited to the method in which the front frame member 410 and the rear frame member 420 are joined to each other, but is not limited thereto, and is not limited to an interference fitting method, an assembly method using a step difference, and a coupling method using a separate coupling member such as a screw. It can be combined with each other in various ways, such as a method.

(Embodiment 3-1) The present invention relates to a photovoltaic exterior panel. In Embodiment 1-1, the cover glass 100 includes a plurality of dots 510 printed in a predetermined pattern A pattern layer 500 is included.

(Example 3-2) The present invention relates to a photovoltaic exterior panel, and in Example 3-1, the dots 510 are printed with an inorganic pigment.

(Embodiment 3-3) The present invention relates to an exterior panel for solar power generation. In Embodiment 3-1, the dots 510 are disposed on the rear surface of the cover glass 100 at regular intervals.

(Example 3-4) The present invention relates to a photovoltaic exterior panel. In Example 3-3, when the dot 510 is projected onto the solar panel 200, the single sunlight At least a portion of the cell 210 is positioned between two adjacent dots 510 .

(Example 3-5) The present invention relates to a photovoltaic exterior panel, and in Example 3-1, the dots 510 are printed with a thickness of 100 to 700 nm.

(Embodiment 3-6) The present invention relates to a photovoltaic exterior panel. In Embodiment 3-1, the pattern layer 500 has a first area S1 on which the dots 510 are printed and Two areas S2 are included, but the thickness of the dots 510 in the first area S1 is thicker than the thickness of the dots 510 in the second area S2.

(Embodiment 3-7) The present invention relates to a photovoltaic exterior panel, and in Embodiment 3-1, the pattern layer 500 has a third region S3 where the dots 510 are printed and a second region S3. The fourth region S4 is included, but the interval between the dots 510 included in the third region S3 is smaller than the interval between the dots 510 included in the fourth region S4.

(Example 3-8) The present invention relates to a photovoltaic exterior panel. In Example 3-2, the inorganic pigment includes at least one of a rust-preventive pigment, a special pigment, and a color pigment.

(Example 3-9) The present invention relates to a photovoltaic exterior panel. In Example 3-2, the dots 510 are printed with a mixture including the inorganic pigment and an additive.

(Example 3-10) The present invention relates to a photovoltaic exterior panel. In Examples 3-9, the additives include a thickener, an antifoaming agent, an emulsifier, a dispersant, a surface control additive, a stabilizer, a leveling agent, and an adhesion promoter. is at least one of

(Example 3-11) The present invention relates to a photovoltaic exterior panel. In Example 3-1, the interval between the dots 510 and the dots 510 is constant.

(Example 3-12) The present invention relates to a photovoltaic exterior panel, and in Example 3-1, the size and shape of the dots 510 are constant.

(Embodiment 3-13) The present invention relates to a photovoltaic exterior panel. In Embodiment 3-1, at least two of the dots 510 have different sizes.

(Embodiment 3-14) The present invention relates to a photovoltaic exterior panel. In Embodiment 3-1, at least two of the dots 510 have different shapes.

(Example 3-15) The present invention relates to a photovoltaic exterior panel, and in Example 3-1, the dots 510 have regular hexagons.

(Example 3-16) The present invention relates to an exterior panel for solar power generation. In Example 3-1, the pattern layer 500 includes a wave pattern 520.

The fact that the pattern layer 500 including the dots 510 is formed on the rear surface of the cover glass 100 means that the front surface of the cover glass 100 is exposed to natural phenomena such as rain, wind, and snow, while the rear surface is exposed. This is to make it easy to maintain the quality of the pattern layer 500 and to maximize self-cleaning capability through the concave-convex surface 110 formed on the front surface of the cover glass 100. The pattern layer 500 including the dots 510 may have a predetermined color, and the solar power generation exterior panel according to the present invention may have a unique color through the pattern layer 500 .

The dot 510 may have a predetermined thickness range as needed. The transmittance may vary according to the thickness of the dot 510, which affects the power generation efficiency of the solar cell disposed behind. Accordingly, the arrangement of the dots 510 and the solar cell 210 is very important.

In the present invention, when the dot 510 is projected toward the solar cell 210, the solar cell 210 may be disposed so as not to overlap with the dot 510. This is because a greater amount of light is transmitted to a portion of the cover glass 100 where the dot 510 is not printed, so that the location of the photovoltaic cell 210 in the portion is more advantageous in consideration of solar power generation efficiency. because it does However, when the distance between the two adjacent dots 510 is relatively narrow, it may be difficult to reduce the size of the photovoltaic cell 210 by that much. Accordingly, when the dots 510 are projected toward the solar cell 210, the solar cell 210 may be disposed such that at least a portion of the solar cell 210 does not overlap with the dot 510.

The dot 510 itself may transmit light to a certain extent or block light. This may be a difference due to the material of the pigment printed with the dot 510 or the thickness of the dot 510 itself. The pattern layer 500 of the present invention includes a first region S1 in which the dot 510 is relatively thick and a second region S2 in which the dot 510 is relatively thin, so that the light transmittance is reduced. The color of a unique pattern can be realized by the difference in color.

In addition, if the dots 510 included in the pattern layer 500 have different intervals therebetween, even if the thickness and color of the dots 510 are the same, a difference between a narrow portion and a wide portion may be realized. To this end, the pattern layer 500 includes a third region S3 with a relatively small interval between the dots 510 and a fourth region S4 with a relatively wide interval between the dots 510. 510, it is possible to implement a color of a unique pattern by the difference in spacing between them. The first area S1 and the second area S2 / the third area S3 and the fourth area S4 may be mixed and used. However, intervals between dots 510 and dots 510 may be equal to each other as needed. In addition, the shapes and sizes of the dots 510 may vary, but there may also be embodiments in which all dots 510 have the same shape and size.

Among the above-described first region S1 to fourth region S4, the solar cell 210 is disposed behind the second region S2 and the fourth region S4 having relatively low light transmittance, if necessary. Otherwise, less solar cells 210 may be disposed compared to other areas. This is because the light transmittance of the second region S2 and the fourth region S4 is lower than that of the other regions, so that the photovoltaic power generation efficiency of the corresponding portion is low.

The shape of the dot 510 may be various, such as a circular shape, an elliptical shape, a polygonal shape, and a star shape. In particular, the shape of the dot 510 is formed in a regular hexagon, so that various patterns can be formed.

In addition, the pattern layer 500 does not simply include only the dots 510, but also includes a fine wavy pattern 520. The fine wave pattern is formed by separating thin wave pattern lines at regular intervals to improve transmittance by light interference.

As described above, at least two of the first region S1, the second region S2, the third region S3, and the fourth region S4 are combined, and light transmittance and photovoltaic power generation efficiency are considered accordingly. When the arrangement of the solar cells 210 is not uniform but irregular, the arrangement of the dots 510 formed on the cover glass 100 and the solar cells 210 included in the solar panel 200 The positions must match each other. At this time, if the cover glass 100 and the solar panel 200 are rectangular or square with the same size as each other, in some cases, one of the cover glass 100 and the solar panel 200 is turned over and bonded to the first area. (S1) - The arrangement of the fourth region (S4) may not match the arrangement of the photovoltaic cell 210. To overcome this, a kind of marker may be formed on at least one of the cover glass 100 and the solar panel 200 . The marker informs the assembly direction of the cover glass 100 and the solar panel 200, and a structure in which a predetermined mark is printed or protrudes and is inserted into the cover glass 100 and the solar panel 200, respectively, is formed. It can be. For example, a hole is formed in a portion (one of four vertices) biased to one side based on the central point in the horizontal and vertical directions of the cover glass 100, and the hole is formed at a position corresponding to the hole of the solar panel 200. An insertion member inserted into the cover glass 100 and the solar panel 200 may be prevented from being erroneously assembled.

The inorganic pigment for printing the dots 510 may be a ceramic pigment. Since the ceramic pigment is material similar to or the same as the cover glass 100, when the dot 510 is formed using the ceramic pigment and heat treated for a predetermined time, the dot 510 stably covers the cover glass 100. By being fused to the glass 100, the durability of the pattern layer 500 including the dots 510 can be improved. The heat treatment temperature of the dot 120 may be in the range of 400 to 600 degrees Celsius.

Anti-corrosion pigment, which is one of the inorganic pigments capable of printing the dots 510 included in the pattern layer 500, is a raw material mixed with the pre-color milling of paint to prevent rust from occurring on metal materials, such as lead trioxide and zinc powder. , strontium chromate, etc., and special pigments are raw materials for imparting a specific metallic feel or for imparting specific functions such as phosphorescence and fluorescence. There are mixtures of solvents in aluminum powder, ferrite, nickel powder, etc., and coloring Pigments are pigments used for coloring paints, and include titanium dioxide, carbon black, iron oxide, zinc oxide, lead white, and the like.

The thickener as an additive is used to control viscosity, impart thickening and thixotropic properties, prevent sedimentation of particles, improve redispersibility, improve flowability, and improve storage stability of particles, and thus have effects on physical properties and storability of paints. The antifoaming agent is a water-based silicone-based antifoaming agent that improves the appearance of the coating film when drying by removing air bubbles in the coating during manufacturing or working. The appearance of the coating film may deteriorate.

When an emulsifier has an oil phase and an aqueous phase in one system, if they are not mixed together, an interface between the two phases is created. When a surfactant is added, the polar group of the active agent dissolves in water and the non-polar group dissolves in the oil phase. Therefore, an emulsifier is used for this purpose, and if an emulsifier is not used, problems may occur during layer separation of paint and formation of a coating film. Dispersants improve the dispersion of pigments and extender pigments in paints, so the visual effect and hiding power of the paint film depend on them, and play an important role in the manufacture, storage, and painting of paints. It is preferable to use a dispersing agent. As a surface conditioning additive, the water-based silicone surface conditioning additive makes the surface of the coating film smooth during operation, improving the appearance of the coating film when drying, and preventing insufficient wetting, poor wettability, cratering formation, and color separation of pigments during the formation of the coating film. It plays a role in improving problems such as

The stabilizer has an effect of increasing the lifetime of the pattern layer 500 including the dots 510 .

The leveling agent controls the flowability of the inorganic pigment to prevent and improve defects.
