[

However, the present invention is not limited thereto. Accordingly, the first and second sealing members 131 and 132, the first cover member 110, or the second cover member 120 may include various materials other than those described above, and may have various shapes. For example, the first cover member 110 or the second cover member 120 may have various shapes (e.g., a substrate, film, sheet, etc.) or material. In addition, a solar cell panel of various structures and systems other than those described above can be applied to the solar cell panel 10.

Referring again to Figs. 1 to 3, the outer shell member 20 may be positioned on the front side of the solar cell panel 10. More specifically, in this embodiment, the outer surface member 20 is positioned on the front surface of the solar cell panel 10, and the outer surface member 20 constitutes the outer surface of the solar cell module 100.

At this time, the outer appearance member 20 may include a plurality of body portions 21 that are inclined or perpendicular to the mounting surface BS and are disposed to be inclined or parallel to the bottom surface GS. Here, the mounting surface BS of the outer member 20 is a surface that is parallel to the front surface (xz plane in the figure) of the solar cell panel 10 while being perpendicular to the bottom surface GS (xy plane in the drawing) And may be the mounting surface of the outer surface member 20 having the widest surface to be mounted on the solar cell panel 10. When the outer surface member 20 has a plurality of mounting surfaces, the inner surface of the plurality of mounting surfaces may be the mounting surface BS.

In the present embodiment, the plurality of body portions 21 may be provided with colored portions 22 on at least the first surface 21a. At this time, the first surface 21a of the body portion 21 may be a surface facing the bottom surface GS or a surface facing downward. In this embodiment, the reflector 24 is further provided on the second surface 21b opposite to the first surface 21a of the body 21 in the present embodiment. That is, in the present embodiment, the body portion 21 may be composed of a colored portion 22 located at the lower portion and a reflecting portion 24 positioned (for example, in contact with) the colored portion 22. According to this, both the effect of the coloring portion 22 and the reflection portion 24 can be realized while simplifying the structure.

Here, the colored portion 22 serves to make the solar cell module 100 appear in a specific color or appearance, and the reflecting portion 24 may reflect light to guide the light in a desired direction.

More specifically, in this embodiment, a plurality of body portions 21 extend in a first direction (x-axis direction in the figure) of the mounting surface BS and a second direction Direction). The first direction may be a direction parallel to the bottom surface GS at the mounting surface BS and the second direction may be a direction perpendicular to the bottom surface GS at the mounting surface BS, Lt; / RTI > As a result, each of the colored portion 22 and the reflective portion 24 constituting the body portion 21 extends in the first direction of the mounting surface BS and is provided in plural in the second direction intersecting the first direction .

At this time, the body portion 21 (i.e., the colored portion 22 and the reflective portion 24) is disposed opposite to the one surface 20a adjacent to the solar panel 10 when installed in the solar panel 10 And may be positioned at an upper position on the other surface 20b. Or the first surface 21a of the body portion 21 has an obtuse angle with the mounting surface BS and the second surface 21b of the body portion 21 is positioned so as to have an acute angle with the mounting surface BS . 6, the body portion (i.e., the colored portion 22 and the reflective portion 24) may be formed so as to be perpendicular to the mounting surface BS or parallel to the bottom surface GS It may be located. With this structure, the first surface 21a of the body portion 21 is arranged to face the bottom surface GS or downward, and the second surface 21b of the body portion 21 faces upward .

When a person looks up and looks at the solar cell module 100 installed in the vertical wall 3 of the building 1 at the lower side of the building 1, the coloring part 22 is recognized as an appearance of the solar cell module 100 do. That is, as shown by a solid line arrow in FIG. 2, the eyes of a person looking up from below the building 1 are not located on the surface of the solar cell panel 100 but on the first surface 21a of the body portion 21 The colored part 22 is visible, so that the solar cell module 100 recognizes that the color of the solar cell module 100 is due to the coloring part 22 and the like. 3, the appearance of a plurality of colored portions 22 located on the entire surface of the solar cell module 100 can be recognized by human eyes.

Accordingly, the appearance of the solar cell module 100 can be controlled by a simple structure. The plurality of colored portions 22 may have the same color so that the solar cell module 100 may have a uniform color and the plurality of colored portions 22 may have a certain pattern, It may also be possible to have a certain image, shape, pattern, etc. on the front surface.

And the solar light provided at the upper portion of the building 1 can be effectively reflected by the reflection portion 24. That is, as shown by the dotted arrow in FIG. 3, the sunlight provided at the top of the building may be reflected by the reflector 24, which is sloped upward toward the outside, and may be incident on the solar cell panel 10. At this time, the reflection portion 24 may be positioned on the upper side of the building so that reflection is performed on the entire surface of the solar cell module 100. Then, solar light can be effectively controlled on the entire surface of the solar cell module 100 and used for photoelectric conversion.

According to this, the amount of light used for photoelectric conversion of the solar cell module 100 can be increased to improve the output of the solar cell module 100, and the amount of light reflected by the solar cell module 100, Reduce glare can be prevented. Conventionally, when a solar cell module is installed in a building, a part of the light reflected by the solar cell module may come into the eyes of a person to cause glare. In this embodiment, the reflection part 24 prevents or mitigates .

Thus, in the present embodiment, since the body portion 21 (i.e., the plurality of colored portions 22 and the plurality of reflective portions 24) extending in the first direction is arranged in plural in the second direction, the body portion 21 (The coloring portion 22 and the reflecting portion 24) or the thickness T of the outer tubular member 20 can be reduced while the coloring portion 22 and the reflecting portion 24) can be realized.

1 to 3, when the angle A between the body portion 21 (for example, the second surface 21b of the body portion 21) and the mounting surface BS is 30 (For example, 45 to 90 degrees) or an angle B between the body portion 21 (for example, the first surface 21a of the body portion 21) and the bottom surface GS, May have an angle B of 0 degrees to 60 degrees (e.g., 0 degrees to 45 degrees). Then, the effect of the coloring portion 22 and the reflection portion 24 can be effectively realized. However, the present invention is not limited thereto, and the body part (i.e., the colored part 22 and the reflective part 24) may be positioned to have various degrees of inclination.

In FIG. 2, for example, a plurality of body portions 21 are disposed parallel to each other. According to this, the structure of the body part 21 or the outer member 20 can be simplified while being simplified. However, the present invention is not limited thereto. Therefore, in consideration of the height of the building, the installation position of the solar cell module 100, the position of sunlight, etc., a plurality of body portions 21 may be provided which are not parallel to each other.

In this embodiment, for example, one colored portion 22 and one reflective portion 24 are combined to form one body portion 21, and a plurality of body portions 21 in the second direction And are spaced apart from each other so as to have a constant pitch (P1, P2). The plurality of colored portions 22 may be spaced apart from each other at a constant pitch P1 in the second direction and the plurality of reflective portions 24 may be positioned apart from each other at a constant pitch P2 in the second direction . The pitch P1 between the plurality of colored portions 22 or the pitch P2 between the plurality of reflecting portions 24 may be larger than the interval between the colored portions 22 and the reflecting portions 24. [ At this time, the pitch P1 between neighboring colored portions 22 or the pitch P2 between neighboring reflecting portions 24 are equal to each other, and the colored portion 22 and the reflecting portion 24 are arranged parallel to each other .

The effect of the colored portion 22 and the reflecting portion 24 can be realized uniformly in the solar cell 10 while the colored portion 22 and the reflecting portion 24 do not interfere with each other, And the number of the reflecting portions 24 can be minimized. Particularly, when the colored portion 22 and the reflective portion 24 are provided together in one body portion 21, the space between the colored portion 22 and the reflective portion 24 is minimized, It is possible to minimize the interference between the portions 24. At this time, the colored portion 22 and the reflective portion 24 constituting one body portion 21 may be in contact with each other, and the colored portion 22 and the reflective portion 24 constituting one body portion 21 may be in contact with each other. (For example, an adhesive layer) may be interposed between the colored portion 22 and the reflective portion 24 constituting one body portion 21, and may be connected to each other through another layer.

For example, the pitch P1 of the plurality of colored portions 22 or the pitch P2 of the plurality of reflecting portions 24 (or the pitch of the body portion 21) may be 80 mm or less. Or the pitch P1 of the plurality of colored portions 22 or the pitch P2 of the plurality of reflecting portions 24 (or the pitch of the body portion 21) Times. The effect of the colored portion 22 or the reflecting portion 24 can be realized on the entire surface of the solar cell panel 100 within this range. Particularly when considering the aforementioned angle of the colored portion 22 or the reflecting portion 24, the plurality of colored portions 22 or the plurality of reflecting portions 24 must have the above-mentioned pitches P1 and P2, The effect of the coloring portion 22 or the reflecting portion 24 can be effectively realized on the entire surface of the substrate 100. [ For example, the interval (e.g., the minimum interval) between the plurality of colored portions 22 or the interval (e.g., the minimum interval) between the plurality of the reflective portions 24 may be 0.1 nm or more. It is limited so that light can be incident between the plurality of colored portions 22 or the plurality of reflective portions 24. [

However, the present invention is not limited to the structure of the above-described body 21, or the arrangement of the colored portion 22 and the reflective portion 24. [

7, the body portion 21 constituted by the colored portion 22 and the reflective portion 24 may be spaced apart from each other with a predetermined space therebetween. At this time, a plurality of body portions 21 (or a plurality of colored portions 22) are provided in the second direction, a plurality of reflecting portions 24 are provided in the second direction, and the body portions 21 And the colored portions 22 may be alternately arranged.

At this time, the body portion 21 and the reflecting portion 24 may be inclined upward toward the outside, orthogonal to the mounting surface BS, or parallel to the bottom surface (GS in FIG. 1, the same applies hereinafter). The lower surface 21a of the body portion 21 and the lower surface 24a of the reflective portion 24 are formed to be spaced apart from the upper surface 21b of the body portion 21 and the lower surface 24a of the reflective portion 24, May be greater than the second distance D2 between the upper surfaces 24a and 24b. The reflective portion 24 does not interfere with the reflective action of the upper surface 24b of the reflective portion 24 located at the lower portion of the body portion 21, It may not hinder the appearance-adjusting action by the elastic member 21b. However, the present invention is not limited thereto, and other variations are possible.

The colored portions 22 and the reflective portions 24 adjacent to each other are spaced apart by a predetermined first distance D1 and the plurality of colored portions 22 are spaced apart from each other by a pitch P1 larger than the first spacing D1, And the plurality of reflecting portions 24 may be arranged to have a pitch P2 larger than the first interval D1. At this time, the pitch P1 of the plurality of colored portions 22 and the pitch P2 of the plurality of reflecting portions 24 may be equal to each other. Then, the colored portion 22 and the reflective portion 24 may be uniformly arranged so as not to interfere with each other maximizing the effect of the colored portion 22 and the reflective portion 24. However, the present invention is not limited thereto, and other variations are possible.

In FIG. 7, for example, a plurality of colored portions 22 are arranged in parallel to each other and a plurality of reflective portions 24 are arranged in parallel to each other and parallel to a plurality of colored portions 22. According to this, the structure of the colored portion 22, the reflecting portion 24, or the outer member 20 can be simplified, and the structure can be easily manufactured. However, the present invention is not limited thereto. Therefore, in consideration of the height of the building, the installation position of the solar cell module 100, the position of sunlight, etc., a plurality of colored portions 22 or reflecting portions 24 may be provided that are not parallel to each other, The colored portion 22 and the plurality of reflecting portions 24 may not be parallel to each other.

In FIG. 2, it is exemplified that both the colored portion 22 and the reflective portion 24 are provided. Accordingly, both the output of the solar cell module 100 and the appearance of the solar cell module 100 can be improved by implementing both the effects of the coloring portion 22 and the reflection portion 24. However, the present invention is not limited thereto. 8, the outer appearance member 22 may have a plurality of body portions 21 having colored portions 22, but the reflective portions 24 may not be provided. Alternatively, as shown in Fig. 9, the outer appearance member 22 may have only the reflecting portion 24 and may not have the colored portion 22 or the body portion 21. Fig.

In the above-described embodiments, the plurality of body portions 21, the plurality of colored portions 22, and the plurality of reflective portions 24 have the same shape, size, and width. However, the present invention is not limited thereto. 10, the outer appearance member 22 is provided with the colored portion 22 and the reflective portion 24, but the width and / or the width of the colored portion 22 and the reflective portion 24 are different from each other, The areas may be different. That is, the reflective portion 24 may be formed to have a larger width or area than the colored portion 22, and the colored portion 22 may be disposed closer to the outer surface or the front surface at a portion of the portion where the reflective portion 24 is formed. Thus, the material cost can be reduced by reducing the area of the colored portion 22 while realizing the effect of the colored portion 22. In addition, various modifications are possible, for example, the reflective portion 24 is formed in only a part of the body portion 21 and the reflective portion 24 is not formed in the other portion.

7 to 10, the colored portion 22 and the reflecting portion 24 are inclined with respect to the mounting surface BS and the bottom surface GS, but the present invention is not limited thereto. Therefore, as shown in Fig. 6, the colored portion 22 and the reflective portion 24 may be perpendicular to the mounting surface BS and parallel to the bottom surface GS. 6 and FIG. 10 illustrate that the colored portion 22 and the reflective portion 24 are in contact with each other. However, another layer (for example, an adhesive layer) may be positioned between the colored portion 22 and the reflective portion 24 , The colored portion 22 and the reflective portion 24 may be spaced apart from each other as shown in Fig. That is, the embodiment shown in FIG. 2 and the modified embodiments shown in FIGS. 6 to 10 can be variously combined with each other, and various other modifications are possible.

Referring to FIGS. 1 to 3 again, according to the present embodiment, the outer appearance of the solar cell module 100 can be improved by the outer member 20 having the colored portion 22. The reflection portion 24 reflects the sunlight provided at the upper portion and can be used for photoelectric conversion, so that the output of the solar cell module 100 can be improved.

Particularly, in the present embodiment, the outer appearance member 20 is formed such that the base portion 26 is located at a portion where the body portion 21 (i.e., the colored portion 22 and the reflective portion 24) T) (for example, a thickness having an error within 10%). The solar cell module 100 can be easily manufactured by forming the outer member 20 in a sheet form or a film form and attaching the outer member 20 to the front or outer surface of the solar cell panel 10.

The base portion 26 may include a transparent material so that light can be incident thereon. The base portion 26 may include a resin having properties such as insulation properties, moisture resistance, and the like and easily manufactured in a sheet form or a film form. For example, the base portion 26 may include ethylene vinyl acetate (EVA), polyethylene terephthalate (PET), or the like. However, the present invention is not limited thereto, and the base portion 26 may include other materials.

More specifically, the coloring portion 22 may be composed of various layers that realize a desired color, pattern, shape, and the like. For example, the coloring portion 22 may comprise a pigment or a dye. In this case, the coloring portion 22 may be a layer containing a resin material and a pigment or a dye, or may be a layer formed by scattering a pigment or a dye using an inkjet or the like. Various materials known as resin materials, pigments, dyes and the like can be used. Further, it may have various shapes (for example, a dot shape) that do not have a layer shape having a uniform thickness as a whole but are located in only a part. Various other variations are possible.

The reflective portion 24 may include a metal or may include a reflective material. As the metal, a material having low reflectance such as aluminum and the like can be used. As the reflective material, a white pigment (for example, titanium oxide (TiO ₂ )) or the like can be used. When the reflective portion 24 is made of metal, the reflective portion 24 may be made of a metal foil or a reflective layer formed by sputtering or the like. In addition, a variety of materials, structures, and the like that can reflect light can be applied to the reflective portion 24.

At this time, the thickness T1 of the colored portion 22 or the thickness T2 of the reflective portion 24 may be smaller than the thickness T of the outer member 20. The coloring portion 22 or the reflecting portion 24 can exhibit a sufficient effect even with a thin thickness and can reduce the material cost in the case of having a thin thickness. The thickness T of the outer tubular member 20 is greater than the thickness T1 of the colored portion 22 or the thickness T2 of the reflective portion 24 so that the colored portion 22 or the reflective portion 24, (24) can be formed with a sufficient width. However, since the thickness T of the outer member 20 is equal to or smaller than the thickness of the first cover member 110 of the solar cell panel 10, the thickness of the outer member 20 is not too thick, It is possible to prevent problems such as being unnecessarily recognized as a separate layer.

For example, the thickness of the first cover member 110 may be 60 mm or less (for example, 4 mm to 40 mm, for example, 4 mm to 20 mm). When the thickness T1 of the colored portion 22 or the thickness T2 of the reflective portion 24 is 1 mm or less (for example, 10 nm to 1 mm) and the thickness T of the outer member 20 is 40 mm or less For example, 10 nm to 40 mm, for example, 20 nm to 20 mm, and more particularly, 20 nm to 10 mm).
