As shown in FIG. 1A, the solar cell module 1 includes a submodule 10 and a frame 11 that covers an end portion of the submodule 10.
Further, as shown in FIG. 1B, a terminal box 12 serving as an outlet for power generated by light reception and an output cable 13 for supplying power to an external load are attached to the back surface of the solar cell module 1. It has been.

FIG. 1C shows the AA ′ cross section of the solar cell module 1.
The submodule 10 has a so-called laminated glass structure in which a cover glass 101, a glass substrate 103 on which a solar cell element 102 is formed, and a back surface protective material 104 are sequentially bonded integrally with a filler 106. .
The submodule 10 and the frame 11 are sealed with a sealing material 14 such as butyl rubber.
In addition, the electrode ribbon 105 attached to the electrode on the solar cell element 102 is sandwiched between the cover glass 101 and the electrode on the solar cell element 102 by the filler 106, drawn into the terminal box 12, and further the terminal The output cable 13 is connected in the box 12.

The cover glass 101 protects the solar cell element 102 from a physical impact or the like while having translucency.
The solar cell element 102 is a photoelectric conversion element that generates power by receiving light. This solar cell element 102 is a CIS-based compound semiconductor thin film and is formed on a glass substrate 103 to form a substrate structure.
The back surface protective material 104 is a sheet that prevents moisture from entering from the outside. This back surface protective material 104 can be comprised by the film formed by bonding together fluororesin, PET, aluminum foil, etc., for example, has low moisture permeability and high intensity | strength.
The electrode ribbon 105 is a strip-shaped lead wire and is made of a conductive metal such as copper.
The filler 106 is formed by integrally bonding and laminating a cover glass 101, a glass substrate 103 on which a solar cell element 102 is formed, and a back surface protective material 104. For example, EVA (ethylene vinyl acetate copolymer) is used for the filler 106.

Moreover, another example of the solar cell module applicable to the recycling method of the solar cell module according to the present embodiment is shown in FIG. This example is a so-called crystalline solar cell module.
As shown in FIGS. 2A and 2B, the solar cell module 2 includes a sub module 20, a frame 21, a terminal box 22, and an output cable 23, similarly to the solar cell module 1.

FIG. 2C shows a BB ′ cross section of the solar cell module 2.
The submodule 20 is configured by integrally bonding a cover glass 201, a solar cell element 202, and a back surface protective material 203 sequentially with a filler 205.
The submodule 20 and the frame 21 are sealed with a sealing material 24 such as butyl rubber.
Further, the lead wire 204 attached to the electrode on the solar cell element 202 is drawn into the terminal box 22 and connected to the output cable 23.
Note that the cover glass 201, the back surface protective material 203, and the filler 205 have the same configurations as the cover glass 101, the back surface protective material 104, and the filler 106 described above with reference to FIG.

The solar cell element 202 is formed by connecting a plurality of unit cells that generate power by receiving light in series by an interconnector, and forms a so-called cell string. The unit cell is made of, for example, single crystal silicon or polycrystalline silicon.
The lead wire 204 is a conducting wire made of a conductive metal such as copper.

As described above, FIG. 1 and FIG. 2 illustrate the solar cell modules (1, 2) to which the solar cell module recycling method according to the present invention is applied. However, the present invention is not limited to the sub modules (10, 20). However, it is applicable if it is formed by laminating a cover glass (101, 201), a solar cell element (102, 202), and a back surface protective material (104, 203).
Accordingly, the solar cell element is not limited to the above, but may be another silicon crystal, amorphous amorphous silicon, or another compound semiconductor thin film, and the laminated structure may be a substrate or a superstrate. It is not limited to any of the above.

Next, the process of the solar cell module recycling method according to the first embodiment of the present invention will be described. In addition, although the case where it applies to the solar cell module 1 shown by FIG. 1 below is demonstrated, it is applicable similarly to the solar cell module 2 shown by FIG.
As shown in FIG. 3, the solar cell module recycling method according to the present embodiment includes a pretreatment step (S11), a crushing step (S12), a softening step (S13), a separation step (S14), an electrode ribbon removal step ( S15), a pulverization step (S16), and a combustion step (S17).

<Pretreatment step (S11)>
First, as a pretreatment, the frame 11, the terminal box 12, and the output cable 13 are removed from the solar cell module 1, and the sealing material 14 is removed.
Thereby, the submodule 10 is taken out from the solar cell module 1.

<Crushing step (S12)>
Subsequently, the glass substrate 103 on which the cover glass 101 and the solar cell element 102 are formed is crushed.
This step is performed by a roll crusher 30 shown in FIG.
The roll crusher 30 includes a conveyance roller 33 that conveys the object to be crushed before and after, and crushes the object to be crushed that has been conveyed by the conveyance roller 33 with the top roller 31 and the bottom roller 32.

The top roller 31 is attached to a drive shaft 311 that is horizontally supported, and a crushing tooth group 312 is provided on the outer peripheral surface thereof. The plurality of crushing teeth 312a constituting the crushing tooth group 312 are pointed protrusions, and the tip ends are directed outward. The crushing teeth 312a can be adjusted in size, size, and density to adjust the size of the crushed pieces produced by crushing the material to be crushed.
The top roller 31 rotates counterclockwise in the figure using an electric motor or a hydraulic motor as a drive source.

Moreover, although the bottom roller 32 is also attached to the drive shaft 321 pivotally supported horizontally, its outer peripheral surface is flat. The outer peripheral surface of the bottom roller 32 may be appropriately coated with a silicon resin or the like in order to increase the friction with the object to be crushed.
The bottom roller 32 rotates in the clockwise direction in the figure using an electric motor or a hydraulic motor as a drive source.

The top roller 31 and the bottom roller 32 are arranged so that the drive shafts 311 and 321 are parallel to each other, with a slight gap, with the top roller 31 on the upper side and the bottom roller 32 on the lower side. Yes.
In addition, workability may be improved by increasing the number of the pair of top rollers 31 and bottom rollers 32.

The submodule 10 includes a back surface protective material 104 on the bottom surface, a glass substrate 103 on which a cover glass 101 and a solar cell element 102 are formed (hereinafter, “a glass substrate 103 on which a cover glass 101 and a solar cell element 102 are formed). "Is referred to as" glass material 100 ") on the upper surface, and is conveyed by the conveyance roller 33 as an object to be crushed. And if the conveyed submodule 10 is sent out between the gaps of the top roller 31 and the bottom roller 32, the glass material 100 will be crushed.
Thereby, while the glass material 100 is crushed, the back surface protection material 104 maintains the sheet shape as a whole even though the hole may be formed. And since this back surface protective material 104 and the glass material 100 are adhered by the filler 106, the crushed glass material 100 is in a state of being adhered on the back surface protective material 104 while being finely crushed, In the subsequent process, the glass material 100 is easily separated from the back surface protective material 104.
In the present embodiment, a roll crusher is used in the crushing process, but the present invention is not limited to this, and a hammer crusher may be used instead of the roll crusher. In this case, a plurality of pointed projections are provided at the tip of the hammer (the portion that crushes the solar cell module), and the degree of crushing of the glass material 100 (the size of the glass material 100 after crushing depends on the density and shape of the projections). May be adjusted.

<Softening step (S13)>
Subsequently, the filler 106 is heated and softened.
As an example of this process, as shown in FIG. 5, the submodule 10 that has undergone the crushing process (S 12) is placed on the transport roller 42 and passed under the heater 41. Far infrared rays are radiated from the heater 41, and the filler 106 that has received the far infrared rays from the heater 41 is heated and softened.
In addition, the conveyance of the submodule 10 by the conveyance roller 41 is performed in the state which made the back surface protection material 104 the lower surface and the glass material 100 the upper surface. The heating in the softening step (S13) may use a halogen lamp as a heat source. Since the halogen lamp has a short time to reach the set temperature, it can be switched on and off instantaneously between heating and non-heating, resulting in reduced power consumption compared to resistance heating. There is an effect. In this way, the filler 106 that bonds the glass material 100 and the back surface protective material 104 is softened, so that the glass material 100 and the back surface protective material 104 are easily separated in the subsequent separation step (S14).

In this softening step (S13), the heating temperature for softening the filler 106 is equal to or lower than the temperature at which the filler 106 such as EVA is not combusted or carbonized, specifically 100 to 250 ° C., preferably 130 to 170. ° C.
The heating method in the softening step (S13) is not limited to the heating by the heater 41. For example, heat is generated so that the transport roller 42 itself can be used as a heat source, and the submodule 10 mounted thereon is directly heated. It is good.

<Separation step (S14)>
Subsequently, the submodule 10 in which the filler 106 is softened is separated into the glass material 100 and the back surface protective material 104.
As an example of this process, as shown in FIG. 6, the blade 51 is arranged so that the blade edge is applied between the glass material 100 and the back surface protective material 104 for the submodule 10 conveyed by the conveyance roller 52. Is fixed.

  The blade 51 is made of metal, and it is easy to scrape the filler 106 by appropriately fixing abrasive grains on the surface thereof by plating.

  When the blade 51 peels off the glass material 100 from the back surface protective material 104 so as to scrape the softened filler 106 as the submodule 10 is conveyed, the glass material 100 that has been crushed by the crushing step (S12) is obtained. Thus, a large number of fragmented pieces 100a are obtained. At this time, the crushed pieces 100a may be sucked and collected in a predetermined container by a suction device.

  Further, another example of the separation step (S14) is that the blade 51 is interposed between the glass material 100 and the back surface protective material 104 while the submodule 10 is sucked and held by the vacuum chuck 61 as shown in FIG. It may be advanced as if cutting with a cutting edge.

  The vacuum chuck 61 includes a chuck table 611 having a large number of air suction holes 612 opened on the upper surface, and a vacuum ejector 613 that sucks air from the air suction holes 612 with compressed air supplied from the outside. The submodule 10 placed on the upper surface of the chuck table 611 is sucked and held on the chuck table 611 by the suction action of the vacuum ejector 613.

  The submodule 10 sucked and held on the chuck table 611 by the vacuum chuck 61 is separated into the glass material 100 and the back surface protection material 104 as the blade 51 advances.

In the separation step (S14) using the vacuum chuck 61, the blade 51 is moved to separate the glass material 100 and the back surface protective material 104. However, the vacuum chuck 61 is not limited to this. The glass material 100 and the back surface protective material 104 may be separated from each other.
Further, the method of holding the submodule 10 is not limited to the vacuum chuck 61, and for example, the tip or four corners of the submodule 10 may be held with a predetermined holding tool.
Also in this example, when the glass material 100 and the back surface protective material 104 are separated by the blade 51, the fragments 100a may be sucked and collected in a predetermined container by a suction device.

<Electrode Ribbon Removal Step (S15)>
Subsequently, the electrode ribbon 105 is removed from the crushed pieces 100a. Note that this step is an optional step, and may be omitted when recycling the glass material 100 does not matter even if the electrode ribbon 105 is mixed.
The removal of the electrode ribbon 105 is carried out by separating it manually from the crushed pieces 100a.
In addition, for the crushed pieces 100a adhered to the electrode ribbon 105 by the filler 106, the filler 106 that bonds the electrode ribbon 105 and the crushed pieces 100a is softened again by heating from about 100 ° C. to about 150 ° C. The electrode ribbon 105 may be peeled off.

<Crushing step (S16)>
Subsequently, the crushed pieces 100a are further finely pulverized.
This step is performed by, for example, a ball mill 71 as shown in FIG.

  The ball mill 71 holds a large number of spherical balls 712 such as stainless steel balls serving as grinding media in a metallic cylindrical rotating container 711. Then, the object to be pulverized is rotated around the axis at a constant speed together with the object to be crushed in the rotating container 711, and the object to be pulverized is pulverized by the impact of dropping or rolling of the ball 712.

  In the rotating container 711, a crushed piece 100a to be crushed and a ball 712 as a pulverizing medium are put. And the crushing piece 100a is grind | pulverized more finely by rotating the rotation container 711 around a shaft center at a fixed speed.

This crushing step (S16) may be performed by the ball mill 81 shown in FIG.
This ball mill 81 is a metal cylindrical rotating container 811, and the whole container has a mesh on the order of several micrometers. Similar to the ball mill 71, the ball mill 81 holds a large number of spherical balls 812 such as stainless steel balls. When the object to be crushed in the rotating container 811 is rotated around the axis at a constant speed, the object to be crushed is crushed by the impact of dropping or rolling of the ball 812, and the crushed pieces 100a are meshed. Classify.
The ball mill 81 classifies the crushed pieces 100a with a mesh. However, the present invention is not limited to this, and a plurality of holes with a predetermined diameter may be provided on the wall of the container to enable classification.
Further, using the mesh ball mill 81, the pulverization step (S16) and the electrode ribbon removal step (S15) may be performed simultaneously. That is, the crushed piece 100a with the electrode ribbon 105 attached thereto is put into the ball mill 81, and the crushed piece 100a may be crushed while the electrode ribbon 105 that cannot pass through the mesh is removed.

<Combustion process (S17)>
Subsequently, the crushed crushed pieces 100a are burned. This step is an optional step, and may be omitted when recycling the glass material 100 does not cause a problem even if the filler 106 is mixed.
In this combustion step (S17), the crushed pieces 100a are put into a predetermined combustion furnace and burned. The filler 106 is thermally decomposed by being sufficiently burned at 450 ° C. or higher.

  Note that the pulverization step (S16) and the combustion step (S17) may be repeated alternately several times. By alternately repeating pulverization and combustion, the filler 106 is more reliably removed, and the crushed pieces 100a are also finely pulverized.

  Through the above steps, the back surface protection material 104 is separated from the solar cell module 1 in which the back surface protection material 104 is bonded to a glass material such as the cover glass 101 and the glass substrate 103, and can be used for recycling as a road repair material or the like. A pulverized material is obtained.

In this example, the softening step (S13) and the separation step (S14) are provided separately. However, the present invention is not limited to this and may be processed as an integrated step.
In this case, for example, the blade 51 itself is heated, and the heated blade 51 is applied to the filler 106 between the glass material 100 and the back surface protective material 104. Then, the submodule 10 is separated into the glass material 100 and the back surface protection material 104 while the filler 51 is softened by the blade 51.

Further, according to another method in which the softening step (S13) and the separation step (S14) are integrated, the conveying roller 52 shown in FIG. 6 and the chuck table 611 of the vacuum chuck 61 shown in FIG. For example, the mounting table on which the submodule 10 is mounted is heated. Then, the submodule 10 is separated into the glass material 100 and the back surface protection material 104 by the blade 51 while the filler 106 is softened by the heat from the mounting table.
According to such a method, the softening step (S13) and the separation step (S14) can be performed at the same time, the work is simplified, and the time required for the series of steps can be shortened. Further, it is not necessary to separately provide a device configuration only for softening the filler 106, and the device configuration is simplified.

Moreover, in this example, although the electrode ribbon removal process (S15) was provided between the separation process (S14) and the pulverization process (S16), the crushing process (S12) and the softening process (S13) are not limited thereto. Or between the softening step (S13) and the separation step (S14).
When the electrode ribbon removal step (S15) is provided between the separation step (S14) and the pulverization step (S16), for example, the filler 106 bonded to the electrode ribbon 105 is heated by heating the electrode ribbon 105. And the electrode ribbon 105 is pulled out from the submodule 10.
In the case where it is provided between the softening step (S13) and the separation step (S14), the electrode ribbon 105 is pulled out from the submodule 10 while the filler 106 is softened by the softening step (S13).

  In this example, the conveyance by the conveyance rollers 33, 42, and 52 may be appropriately provided with baffle plates or the like to control the speed and adjust the time for crushing, softening, or separation. Further, the conveyance itself may be slid on a predetermined table regardless of the conveyance rollers 33, 42, 52, and the method is not particularly limited.

Next, the process of the solar cell module recycling method according to the second embodiment of the present invention will be described. In the following, as in the first embodiment, the case where the present invention is applied to the solar cell module 1 shown in FIG. 1 will be described. However, the same applies to the solar cell module 2 shown in FIG. It is.

The pretreatment step (S21), the crushing step (S22), the softening step (S23), the separation step (S24), and the combustion step (S28) are respectively the pretreatment step (S11) and the crushing step in the first embodiment. (S12), softening step (S13), separation step (S14), and combustion step (S17).

  In this example, a preliminary pulverization step (S25) is provided between the separation step (S24) and the electrode ribbon removal step (S26). In the preliminary pulverization step (S25), the crushed pieces 100a are once finely pulverized to some extent.

  Then, in the electrode ribbon removing step (S26), the crushed pieces 100a finely pulverized to some extent are passed through a sieve on which a mesh of a predetermined size is formed, and only the crushed pieces 100a are sieved, whereby the crushed pieces 100a and the electrode ribbon 105 are removed. And the electrode ribbon 105 is removed.

Then, the process proceeds to the main crushing step (S27), and the crushed pieces 100a from which the electrode ribbon 105 has been removed are crushed more finely.
