The present invention relates to a solar module.

A device that converts the energy of photons generated from the sun into electrical energy through the photoelectric effect is called a solar cell, and an assembly of two or more solar cells connected in series or parallel to a single circuit is called a photovoltaic module.

1 to 4, the solar module 100 according to the first embodiment of the present invention includes a solar cell 110, a first encapsulant 120, a second encapsulant 130, and a first substrate. 140 and a second substrate 150.

1 to 4 in sequence, the solar module 100 according to the first embodiment of the present invention includes a plurality of first solar cells 110 having lengths in a first direction (X-axis direction). It is inserted into and fixed to the encapsulant 120 and the second encapsulant 130, and may be spaced apart from each other in the second direction (Y-axis direction).

First, referring to FIG. 1 , a plurality of solar cells 110 may be spaced apart from each other in the longitudinal direction (X-axis direction) within the first encapsulant 120 .

Here, the solar cell 110 may be formed in a shape having a thickness and a width.

For example, the solar cell 110 may be a thin-film solar cell 110 having a thickness of 10 nm to 10 um or a silicon solar cell 110 having a thickness of 50 to 300 um.

Specifically, the type of solar cell 110 applied in the present invention is not limited, but a silicon solar cell or the like can be applied in the present invention.

That is, silicon solar cells can be classified in various ways according to the type and structure of the substrate used, and can be largely classified into multicrystalline and single crystal silicon solar cells according to the crystal characteristics of the light absorption layer.

A single-crystal solar cell, a typical silicon solar cell, is a solar cell made of a single-crystal silicon wafer as a substrate. In addition, a silicon solar cell may be a tandem layer in which solar cells absorbing light of different wavelengths are stacked on a silicon solar cell, or a triple junction layer in which solar cells absorbing light of another wavelength are further stacked on top of the silicon solar cell. (Triple Junction), etc., or manufactured in a hybrid structure to increase the conversion efficiency to a level higher than that of a conventional silicon solar cell.

The first encapsulant 120 is preferably made of a material that is transparent, flexible, easily deformable, and curable by heat or UV. On the other hand, the first encapsulant 120 may be configured in the form of a film capable of maintaining its shape by being bent.

For example, the first encapsulant 120 may be made of EVA material. However, in the present invention, the first encapsulant 120 is not limited to EVA, and all materials usable as encapsulants of solar modules may be used.

Meanwhile, the first encapsulant 120 may prevent corrosion due to moisture permeation and protect the plurality of solar cells 110 from impact. The first encapsulant 120 may be made of materials such as ethylene vinyl acetate (EVA), polyolefin (PO), IONOMER, polyvinyl butyral (PVB), and silicone resin.

A plurality of solar cells 110 may be spaced apart from each other in the first encapsulant 120 , and the first encapsulant 120 may cover the entire surface of the solar cell 110 .

Here, the first encapsulant 120 may include an accommodating portion 121 accommodating each of the plurality of solar cells 110 and a connection portion 122 connecting the accommodating portions 121 to each other.

A virtual bending line 1 may be formed in the connection part 122, and one end or both ends of the connection part 122 is bent along the bending line 1 so that the receiving part 121 and the connection part 122 form an angle between them. can have

Here, it is preferable that the first encapsulant 120 is not restored to its original shape when the external force is removed after being hardened after being bent into a set shape. Of course, depending on the material of the first encapsulant 120, the original shape may not be restored when the external force is removed without a hardening process.

Then, referring to FIG. 3 , the second encapsulant 130 is made of a transparent material and can completely surround the bent first encapsulant 120 after accommodating the plurality of solar cells 110 .

In addition, the second encapsulant 130 may have the same or different refractive index from the first encapsulant 120 .

Here, when the refractive indices of the first encapsulant 120 and the second encapsulant 130 are the same, transparency may be improved according to the first encapsulant 120 and the second encapsulant 130, and vice versa. When the refractive indices of the first encapsulation material 120 and the second encapsulation material 130 are different, the transparency may be reduced, but the difference in refractive index between the interfaces of the first encapsulation material 120 and the second encapsulation material 130 results in light Since refraction and reflection occur, the photoelectric efficiency of the solar module may be improved.

Meanwhile, the outer surface of the first encapsulant 120 may be spaced apart from the outer surface of the second encapsulant 130 . That is, the second encapsulant 130 may completely surround the front surface of the first encapsulant 120 .

The first substrate 140 may have a multi-layer structure such as a layer that prevents penetration of moisture and oxygen, a layer that prevents chemical corrosion, and a layer that has insulating properties. For example, the first substrate 140 may have a PVF (polyvinyl fluoride), PVDF (polyvinylidene fluoride), PET (polyethylene terephtalate), and low iron tempered glass.

However, the first substrate 140 is not limited to these materials and may be made of a transparent substrate like the second substrate 150 .

The second substrate 150 is formed in the form of a film and disposed in front of the module, and may be made of tempered glass having high transmittance and excellent breakage prevention function to transmit incident light or a high transmittance fluorine film.

In this case, the tempered glass may be low iron tempered glass having a low iron content.
