BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a blind comprising a solar cell in the form of a fiber weave, and more particularly, to a blind that is secured with flexibility by applying a solar cell in the form of a fiber weave.

The blind is installed in a window of a building or the like in order to prevent direct sunlight from entering the room from the outside of the building or to protect the privacy of the room. Conventional blinds have performed only intrinsic functions such as external light shielding and privacy protection. However, as interest in pollution-free energy has increased in recent years, efforts to add additional functions for producing electricity by applying solar cells to vertical blinds .

Solar cells are devices that convert sunlight energy into electrical energy. Generally, a solar cell is equipped with a semiconductor material, and when light is received, electrons and holes are generated inside, and generated electric charges move to P and N poles, and a potential difference is generated to flow a current. Currently developed solar cells are various, such as organic solar cells, silicon solar cells, CIGS solar cells, and dye-sensitized solar cells. Among them, Dye-Sensitized Solar Cell (DSSC) has a lower manufacturing cost, higher energy conversion efficiency compared to the conventional silicon solar cell, and can produce a cell capable of transparency and bending, It is advantageous to use it.

However, since such a dye-sensitized solar cell uses a glass substrate having a conductive film formed on its surface as an electrode, flexibility is low and it is difficult to apply it to a blind of a fiber material.

Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide a dye-sensitized solar cell in the form of a textile weave.

It is still another object of the present invention to eliminate the possibility of contact between the photoelectrode and the counter electrode in the process of manufacturing the photoelectrode of the dye-sensitized solar cell applied to the blind.

According to an aspect of the present invention, there is provided a solar cell blind comprising a plurality of solar cell blind bodies, wherein each of the plurality of solar cell blind bodies comprises: a fabric fabric; And a plurality of dye-sensitized photovoltaic cells woven with the photo-electrode, the counter electrode, and the insulator in the form of a wire, the plurality of dye-sensitized photovoltaic modules being spaced apart from each other on the fabric fabric.

In the dye-sensitized solar cell module, at least two of the photo-electrodes are disposed in an inclined state, and the counter electrode is disposed at a distance from the photo-electrode. And the rest of the insulator may be used as the insulator for use as a weave.

Each of the upper insulators crosses one slope in turn, and each slope can intersect two wefts across the two upper insulators.

Two intersections where the inclination is located higher than the upper insulator are formed in a continuous manner in the oblique direction and two spaced insulators may be present in the interval between consecutive intersections in an oblique direction.

The intersection points may be formed by crossing one slope in the weft direction.

According to another embodiment of the present invention, there is provided a solar cell blind including a plurality of solar cell blind bodies, wherein each of the plurality of solar cell blind bodies includes a dye-sensitized solar cell, A solar cell blind, which is embodied as a solar cell, is provided.

According to the present invention, by applying a dye-sensitized solar cell in the form of a fiber weave to a blind, the flexibility in the blind whole area can be secured.

Further, according to the present invention, a dye-sensitized solar cell applied to a blind can be manufactured by an easy process.

According to the present invention, in the process of manufacturing the photoelectrode of the dye-sensitized solar cell applied to the blind, the possibility of contact between the photoelectrode and the counter electrode can be prevented in advance.

Referring to FIG. 4, the dye-sensitized solar cell module 120 is formed in a woven shape.

Specifically, the dye-sensitized solar cell module 120 is composed of a plurality of optical electrodes 121, a counter electrode 122, and an insulator 123 in the form of a wire.

The optical electrode 121 and the counter electrode 122 are inclined, and the insulator 123 is used as a weft and a warp.

First, the arrangement structure between the optical electrode 121, the counter electrode 122, and the insulator 123 used as the inclined surface will be described.

Two or more optical electrodes 121 are sequentially arranged, and the counter electrodes 122 are arranged one by one. A certain number of light insulating insulators 123 are sequentially arranged between the light electrode 121 and the counter electrode 122. 2, two insulators 123 are disposed in parallel between the light electrode 121 and the counter electrode 122. It is preferable that at least three light insulators 123 are disposed between the light electrode 120 and the counter electrode 122, And the counter electrode (122).

On the other hand, the weaving insulator 123 is used as the weft of the solar cell of the woven fabric. Looking at the structure of the solar cell weave, each weave crosses one slope. On the other hand, each slope crosses two wefts and crosses two wefts.

In the entire woven fabric, two intersecting points (S), that is, points having an inclination higher than the weft in the drawing are formed continuously in the oblique direction, and in the interval between consecutive intersections (S) (123) exist. In addition, the intersection points S are alternately formed one by one across the inclination in the weft direction.

The lightweight insulator 123 is formed of glass fiber or the like made of an insulating material and the lightweight insulator 123 has a function of maintaining insulation between the optical electrode 121 and the counter electrode 122 do.

Thereafter, an insulator used as a weft is disposed to make a weft / warp structure. In the insulator used as the weft, two mutually adjacent insulators are woven in the same structure in relation to the warp, so that the two insulators can be warp and weave in a single step, and advantages in the manufacturing process can be obtained. While this process advantage can be achieved, the rigidity of the entire woven fabric can be maintained sufficiently because one insulator crosses one incline in the weft direction.

When the solar cell weave is manufactured, it is sealed and the electrolyte is filled therein. If the color of the sealing member used for sealing is selected to be the same or similar to the color of the fabric of the solar cell blind body, then visually it will be no different from the conventional blind.
