Description
Technical Field
The present invention relates to a method for assembling a solar cell module, and more particularly, to a solar cell module including a plurality of support members disposed between a front glass plate and a back glass plate, the support members including a light reflecting structure.
Background
Solar cells, which are photoelectric devices that convert light energy into electrical energy, are one of the important alternative energy sources due to low pollution and low cost, and the fact that solar energy, which is not an absolute source, can be used as an energy source. The basic structure of the solar cell is formed by bonding a P-type semiconductor and an N-type semiconductor, when sunlight irradiates a solar substrate with the P-N junction, light energy excites electrons in silicon atoms to generate convection of electrons and holes, and the electrons and the holes are respectively gathered at two ends of a negative electrode and a positive electrode under the influence of a built-in electric field formed at the P-N junction, so that voltage is generated at two ends of the solar cell. At this time, the electrodes can be used to connect two ends of the solar cell to an external circuit to form a loop, and further to generate current, which is the principle of solar cell power generation.
The solar cell module includes many materials, such as a front glass plate, a first encapsulant, a plurality of solar cells, a second encapsulant, a back sheet, and the like. Referring to fig. 1, when a constructor 8 installs a solar cell module 9, it is often the case that the constructor steps on the solar cell module 9 due to space limitation, and this action may stress a part of the solar cell module 9. If the stress is too large, not only the solar cell module 9 will be bent and deformed, but also the solar cells inside will be micro-cracked, and after the micro-cracking of the solar cells occurs, the power generation efficiency of the solar cell module 9 will be reduced in the future, and many problems in reliability will be caused, which will affect the service life of the solar cell module 9.
Therefore, it is desirable to provide a solar cell module and an assembling method thereof, which can solve the above problems.
Disclosure of Invention
An object of the present invention is to provide a solar cell module including a plurality of support members disposed between a front glass plate and a back glass plate, the support members including a light reflecting structure.
In accordance with the above object, the present invention provides a solar cell module comprising: a front glass plate; a back glass plate disposed opposite to the front glass plate; a plurality of solar cells disposed between the front glass plate and the back glass plate; the packaging material is arranged between the front glass plate and the back glass plate and covers the solar cells; and a plurality of supporting members, which are arranged between the front glass plate and the back glass plate and are positioned in the gaps among the solar cells, wherein the supporting members comprise a body and a light reflection structure, the light reflection structure is positioned on the peripheral inclined plane of the body, and the body is provided with an upper abutting surface and a lower abutting surface which respectively correspond to the front glass plate and the back glass plate.
The invention further provides an assembly method of the solar cell module, which comprises the following steps: disposing a first packaging material on a front glass plate; disposing a plurality of solar cells and a plurality of support members on the first encapsulant, wherein the support members are disposed in gaps between the solar cells, the support members including a body and a light-reflecting structure disposed on the body; arranging a second packaging material on the solar cells and the supporting pieces; disposing a back glass plate on the second packaging material, and disposing opposite to the front glass plate; and stacking and assembling the front glass plate, the first packaging material, the solar cells, the supporting pieces, the second packaging material and the back glass plate into a solar cell module by using a laminating process.
Importantly, when the thickness of the supporting pieces is larger than that of the solar cell, if a constructor steps on the solar cell module when installing the solar cell module, the supporting pieces can increase the mechanical strength of the local stress of the solar cell module so as to prevent the local bearing pressure of the solar cell module and further prevent the internal solar cell from generating microcracks.
More importantly, the supporting member comprises a body and a light reflecting structure, wherein the light reflecting structure is positioned on the peripheral inclined plane of the body. The light reflection structure can be used for reflecting incident light from the front glass plate to the front glass plate and forming total reflection, so that more light rays are reflected to the solar cells, and the power generation amount of the solar cell module is increased.

Detailed Description
In order to make the aforementioned and other objects, features and characteristics of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Please refer to fig. 2 and 3, which are schematic perspective and partial cross-sectional views of a solar cell module according to a first embodiment of the invention. The solar cell module 1 includes: a front glass plate 11, a back glass plate 15, a plurality of solar cells 13, a packaging material 12 (including a first packaging material 12a and a second packaging material 12b), and a plurality of supporting members 16. The back glass plate 15 and the front glass plate 11 are disposed opposite to each other. For example, the thickness of the back glass plate 15 and the front glass plate 11 is about 2 to 2.5mm each. The solar cells 13 are disposed between the front glass plate 11 and the back glass plate 15. The encapsulant 12 is disposed between the front glass plate 11 and the back glass plate 15, and covers the solar cells 13. For example, the first encapsulant 12a is disposed between the front glass plate 11 and the solar cells 13, the second encapsulant 12b is disposed between the back glass plate 15 and the solar cells 13, and the first encapsulant 12a and the second encapsulant 12b are bonded together. For example, the first encapsulant 12a and the second encapsulant 12b may be Ethylene Vinyl Acetate (EVA) material.
The supporting members 16 are also disposed between the front glass plate 11 and the back glass plate 151 and in the gaps between the solar cells 13. In the present embodiment, the gaps between the solar cells 13 include a plurality of first gap regions 131 (e.g., diamond-shaped areas) between any four adjacent solar cells 13, and the supporting members 16 are located in the first gap regions 131. The gap between the solar cells 13 further includes a plurality of second gap regions 132 (e.g., rectangular areas) between any two adjacent solar cells 13, and the supporting members 16 are located in the second gap regions 132. In other embodiments, the supporting members 16 may be located only in the first gap regions 131, or the supporting members 16 may be located only in the second gap regions 132.
Importantly, when the thickness T1 of the supporting members 16 is greater than the thickness T2 of the solar cell 13 (e.g., about 200 μm), if the constructor steps on the module when installing the solar cell module 1, the supporting members 16 can increase the mechanical strength of the local stress of the solar cell module 1, so as to prevent the local stress of the solar cell module 1 and further prevent the micro crack (micro crack) of the solar cell 13 inside. Preferably, the thickness T1 of the supporting members 16 may be smaller than the stacked thickness of the laminated packaging material 12 (e.g., the first and second packaging materials 12a, 12b) and the solar cell 13. For example, the first and second sealing materials 12a and 12b have a thickness of about 400 to 450 μm after lamination. The main body 161 has an upper contact surface 1611 and a lower contact surface 1612 corresponding to the front and rear glass plates 11, 15, respectively. The upper contact surface 1611 at least partially contacts the inner surface 111 of the front glass plate 11, and the lower contact surface 1612 at least partially contacts the inner surface 151 of the back glass plate 15. The above at least partial contact: that is, if the contact is maximum, the upper contact surface 1611 can be fully contacted with the inner surface 111 of the front glass plate 11, and the lower contact surface 1612 can also be fully contacted with the inner surface 151 of the back glass plate 15; however, in general, there is still a little gap between the abutting surface and the two surfaces of the inner surface, where the first and second sealing materials 12a and 12b are not completely extruded and remain in the gap between the two surfaces during lamination, so that the so-called at least partial contact is formed.
More importantly, the supporting member 16 includes a main body 161 and a light reflecting structure 162, wherein the light reflecting structure 162 is disposed on the peripheral inclined surface 163 of the main body 161. The light reflection structure 162 includes first and second light reflection regions 162a, 162b, and the first and second light reflection regions 162a, 162b are respectively disposed at the upper half portion 161a and the lower half portion 161b of the main body 161. When the solar cells 13 are single-sided light-guiding type solar cells, the first and second light-reflecting regions 162a, 162b of the light-reflecting structure 162 can be used to reflect the incident light L from the front glass plate 11 to the front glass plate 11 and form total reflection, so that more light is reflected to the solar cells 13 to increase the power generation of the solar cell module 1. In the present embodiment, the body of the supporting members 16 may be made of glass material, Acrylic (i.e., polymethyl methacrylate, PMMA) material or Melamine resin (i.e., Melamine resin). For example, the light reflection structure 162 may include a metal film (metal film) to increase the light reflection effect. The metal film is made of aluminum (Al), silver (Ag), copper (Cu) or gold (Au). The body 161 (the upper half 161a and the lower half 161b) may be a cone or a polygonal cone with a narrow top and a wide bottom, that is, the body 161 (the upper half 161a and the lower half 161b) may have a trapezoidal cross section with a narrow top and a wide bottom, and the metal film is formed on the peripheral inclined plane 163 of the upper half 161a and the lower half 161b of the body 161, and the peripheral inclined plane 163 may be designed with respect to the angle of the reflective surface, so that the peripheries of the first and second light reflecting regions 162a and 162b are tapered toward the front glass plate 11.
Referring to fig. 4, in another embodiment, the material of the body 161 of the supporting members 16 may be glass, and the body 161 of the supporting members 16 may be integrally formed with the back glass 15.
Please refer to fig. 5, which are schematic partial cross-sectional views of a solar cell module according to a second embodiment of the invention. The solar cell module 1' of the second embodiment is substantially similar to the solar cell module 1 of the first embodiment, like elements being denoted by like reference numerals, with the main differences: the light reflecting structure 162 'includes first and second light reflecting regions 162 a', 162b ', which are respectively located at the upper half portion 161 a' and the lower half portion 161b 'of the body 161'. When the solar cells 13 are double-sided light-guiding type solar cells, the first light-reflecting region 162a ' is used for reflecting the incident light L from the front glass plate 11 to form total reflection, and the second light-reflecting region 162b ' is used for reflecting the incident light L from the back glass plate 15 to form total reflection, so that more light is reflected to the solar cells 13 to increase the power generation of the solar cell module 1 '. For example, the light reflection structure 162' may further include a metal film (metal film) to increase the light reflection effect. The upper portion 161a 'of the body 161' may be in the shape of a cone or a polygonal cone with a narrow top and a wide bottom, i.e., the upper portion 161a 'of the body 161' may have a trapezoid with a narrow top and a wide bottom; the lower part 161b ' of the body 161 ' may be a cone or a polygonal cone with a wide top and a narrow bottom, that is, the lower part 161b ' of the body 161 ' may have a trapezoid with a wide top and a narrow bottom, and the upper part 161a ' and the lower part 161b ' of the body 161 ' are connected with each other. The metal film is formed on the peripheral slope 163 ' of the upper half 161a ' and the lower half 161b ' of the main body 161 ', and the peripheral slope 163 ' can be designed with respect to the angle of the reflective surface, such that the periphery of the first light reflective region 162a ' is tapered toward the front glass plate 11, and the periphery of the second light reflective region 162b ' is tapered toward the back glass plate 15.
Similarly, the main body 161 ' also has an upper contact surface 1611 ' and a lower contact surface 1612 ' corresponding to the front and rear glass plates 11, 15, respectively. The upper contact surface 1611 'at least partially contacts the inner surface 111 of the front glass plate 11, and the lower contact surface 1612' at least partially contacts the inner surface 151 of the back glass plate 15.
Please refer to fig. 6, which is a flowchart illustrating an assembly method of a solar cell module according to an embodiment of the invention. Fig. 7 is an exploded cross-sectional view of a solar cell module according to an embodiment of the invention before lamination. The method for assembling the solar cell module includes: in step S102, a first encapsulant 12a is disposed on a front glass plate 11. In step S104, a plurality of solar cells 13 and a plurality of supporting members 16 are disposed on the first encapsulant 12a, wherein the supporting members 16 are located in the gaps between the solar cells 13, the supporting members 16 include a body 161 and a light reflection structure 162, and the light reflection structure 162 is located on the body 161. In step S106, a second encapsulant 12b is disposed on the solar cells 13 and the supporters 16. In step S108, a back glass plate 15 is disposed on the second encapsulant 14 and opposite to the front glass plate 11. In step S110, a lamination process is used to assemble the front glass plate 11, the first encapsulant 12a, the solar cells 13, the supporting members 16, the second encapsulant 12b and the back glass plate 15 into a solar cell module 1 by stacking, as shown in fig. 3.
In this embodiment, the lamination process is to heat the first encapsulant 12 and the second encapsulant 14 under vacuum and apply pressure to cool them to form a solidified light-transmissive polymer. After the first encapsulant 12a and the second encapsulant 12b are cross-linked to form the encapsulant 12, the supporting members 16 are contacted with the front glass plate 11 or the back glass plate 15. In other embodiments, the first encapsulant 12 and the second encapsulant 14 may be bonded to the encapsulant 12 without the support members 16 contacting the front glass plate 11 or the back glass plate 15.
In the present embodiment, the light reflection structure 162 includes first and second light reflection regions 162a, 162b, the first and second light reflection regions 162a, 162b are respectively located at the upper half portion 161a and the lower half portion 161b of the main body 161, and the peripheries of the first and second light reflection regions 162a, 162b are tapered toward the front glass plate 11, as shown in fig. 3. In other embodiments, the light reflection structure 162 'may include first and second light reflection regions 162 a', 162b ', the first and second light reflection regions 162 a', 162b 'are respectively located at the upper half 161 a' and the lower half 161b 'of the body 161', the periphery of the first light reflection region 162a 'is tapered toward the front glass plate 11, and the periphery of the second light reflection region 162 b' is tapered toward the rear glass plate 15, as shown in fig. 5.
Referring to fig. 8, in another embodiment, the step S104 of disposing the plurality of solar cells 13 and the plurality of supporters 16 on the first encapsulant 12a may include: disposing a plurality of solar cells 13 on the first encapsulant 12 a; forming a plurality of holes 121 in the first encapsulant 12 a; and the supporting members 16 are fixed in the holes 121 of the first packaging material 12 a. Since the supporting members 16 are first fixed in the holes 121 of the first packaging material 12a, the falling of the supporting members 16 can be reduced in the subsequent steps S106, S108 and S110, thereby reducing the processing time.
Referring to fig. 9, in another embodiment, the step of disposing the plurality of solar cells 13 and the plurality of supporters 16 on the first encapsulant 12a may include: forming a plurality of holes 121 in the first sealing material 12a in advance; fixing the supporting members 16 in the holes 121 of the first packaging material 12 a; and a plurality of solar cells 13 are disposed on the first encapsulant 12 a. Since the first encapsulant 12a can be pre-formed with the plurality of holes 121 in the factory, it is not necessary to form the plurality of holes 121 in situ, thereby reducing the process time.
In summary, the present invention is described only in the preferred embodiments or examples for solving the problems, and is not intended to limit the scope of the present invention. The scope of the invention is to be determined by the following claims and their equivalents.
