Description

  The present invention includes a plurality of solar cells provided with electrodes on the surface, a wiring material that is connected to the electrodes and electrically connects adjacent solar cells, and a transparent surface that is disposed opposite to the surface side of the solar cells. And a protective member disposed opposite to the back surface side of the solar battery cell, and the solar battery cell and the wiring member are interposed between the transparent substrate and the protective member by the transparent sealing material. The present invention relates to a sealed solar cell module.

  2. Description of the Related Art Conventionally, a solar cell module with improved design properties has been proposed without cost and labor (see Patent Document 1).

  This solar cell module includes a back surface coating material, a cell back surface sealing layer provided on the back surface coating material, a solar cell module provided on the cell back surface sealing layer, and a plurality of solar cells that are arranged and connected to each other with a wiring material. A battery cell, a colored concealment tape for concealing the wiring material provided on the wiring material, a cell surface sealing layer provided on the solar cell and the colored concealment tape, and provided on the cell surface sealing layer And a translucent light-receiving surface covering plate.

  That is, a colored concealment tape (that is, a light shielding tape) is provided on the surface of a wiring material (hereinafter also referred to as “interconnector”) mounted on the surface of the solar battery cell, and viewed from the light receiving surface side of the solar cell module.

Utility Model Registration No. 3143376

  However, the structure in which the light shielding tape is directly provided on the surface of the interconnector mounted on the surface side of the solar battery cell has the following problems.

  That is, the surface of the interconnector is often coated with solder or the like in advance. By mounting (coating) solder etc. on the surface of the interconnector in advance, when connecting the interconnector and the electrode of the solar battery cell, the interconnector and the electrode are simply brought into contact with each other and heated. A good electrical connection between the electrodes can be obtained. However, due to the variation in the amount of solder during solder mounting, solder irregularities may be formed on the surface of the interconnector, and the irregularities may sometimes become protrusions.

  When the light-shielding tape is pasted on the interconnector where the unevenness of the solder is generated on the surface in this way, the tape surface also becomes uneven. The uneven surface is irregularly reflected when exposed to external light, and the degree of reflection is also changed.

  As another problem, for example, when stored for a long time in a high-temperature and high-humidity environment, moisture may permeate the inside of the module, which may reduce the adhesive strength of the light-shielding tape. When the adhesive strength is lowered, the light shielding tape is peeled off from the interconnector, and there is a problem that the peeled interface is visually recognized as a deterioration in display quality.

  In addition, due to the solder coating on the surface of the interconnector, a solvent such as flux remains on the surface of the interconnector. Therefore, there is a problem that the adhesion between the interconnector and the light shielding tape is originally poor.

  The present invention was devised to solve such problems, and it is possible to reliably prevent the occurrence of the above problems by directly attaching a light-shielding tape to an interconnector and to provide a solar cell module excellent in design. It is in.

FIG. The bus bar electrode 16a is disposed so as to face the front and back.

  Here, the width | variety of the bus-bar electrode 16a and the back surface electrode 17 is 3 mm in this embodiment.

It is AA sectional view taken on the line of FIG. 1A.

  The solar cell module 1 of the present embodiment includes two solar cells 10 each having a front electrode 16 and a back electrode 17, a bus bar electrode 16 a of the front electrode 16 of one solar cell 10, and the other solar cell 10. The interconnector 12 that is a wiring member that is connected to the back electrode 17 and electrically connects the adjacent solar cells 10 in series with each other and the front side of the solar cell 10 (upper side in FIG. 1C) are arranged to face each other. A transparent substrate 13 and a protective member 14 disposed opposite to the back surface side (lower side in FIG. 1C) of the solar battery cell 10, and the solar battery cell 10 and the interconnector 12 are provided with a transparent seal. The structure is sealed between the translucent substrate 13 and the protective member 14 by the stopper 15.

  The interconnector 12 has a configuration in which solder is coated (solder plating process) on the outer surface of a base material formed in an elongated strip shape. Although it does not specifically limit as a material of a base material, For example, metals, such as copper, can be used. Also, the material of the solder is not particularly limited. For example, an alloy of tin and lead or an alloy of tin, silver, and copper can be used. In addition, the width of the interconnector 12 is 2 mm in this embodiment. The thickness is 0.2 mm.

  And one side (left side in FIGS. 1A to 1C) of the interconnector 12 is solder-connected to the bus bar electrode 16a on the surface of the left side solar cell (hereinafter referred to as the left side solar cell) 10 in the figure, and the other side (FIG. 1A is connected to the back electrode 17 on the back surface of the solar cell on the right side in the drawing (hereinafter referred to as the right solar cell). Also, the output lead wire 12a, which is a wiring material for extracting power, is soldered to the bus bar electrode 16a on the surface of the right solar cell 10, and another output lead wire 12b, which is a wiring material for extracting power, is connected to the left solar cell. The back electrode 17 on the back surface of the cell 10 is soldered.

  In addition, the output lead wire 12b solder-connected to the back surface electrode 17 on the back surface of the left side solar cell 10 is extended toward the right side solar cell 10 and is on the portion of the protective member 14 facing the back surface of the left side solar cell 10. It is led out of the solar cell module 1 through the provided opening 14c. Further, the output lead wire 12 a solder-connected to the bus bar electrode 16 a of the right solar cell 10 is extended in the horizontal direction as it is and led out of the solar cell module 1.

  In the present embodiment, only one bus bar electrode 16a is formed in the solar battery cell 10, but two bus bar electrodes 16a may be formed in parallel. In this case, naturally, the back electrode 17 is also formed in parallel (two rows), and the two interconnectors 12 are also used in parallel. In the present embodiment, the output lead wires 12a and 12b are also configured by solder coating (solder plating treatment) on the outer surface of the base material formed in an elongated strip shape, and the width thereof is the interconnector 12. The thickness is 2 mm, and the thickness is 0.2 mm.

  The solar cell 10 and the interconnector 12 and the output lead wires 12a and 12b (parts connected to the electrodes) 12a and 12b configured as described above are made transparent by the translucent sealing material 15 and the translucent substrate 13 and the protective member 14. It is the structure sealed between. The sealing material 15 is formed of a material that can be elastically deformed, and has a thickness sufficient to maintain elastic force even by deformation due to thermal expansion / contraction of the interconnector 12 and the output lead wires 12a and 12b. For example, it is formed to a thickness of about 400 μm.

  In such a configuration, in the present embodiment, a portion facing the interconnector 12 and the output lead wire 12a on the surface (surface opposite to the light receiving surface 13a) 13b of the translucent substrate 13 facing the solar cell 10. It is set as the structure which provided the light-shielding material 18 in the. That is, when the solar cell module 1 is viewed from the light receiving surface 13a side by this light shielding material 18 (that is, when the front surface side of the solar cell 10 is viewed through the translucent substrate 13), the interconnector 12 and the output The lead wire 12a is covered so as not to be seen (see FIG. 1A).

  In this structure, as shown in FIG. 1C, since the light shielding material 18 is not attached to the interconnector 12, even if the surface of the interconnector 12 has unevenness due to solder coating, the unevenness directly affects the light shielding material 18. There is nothing. Therefore, when the solar cell module 1 is viewed from the light receiving surface 13a side (that is, when the surface side of the solar cell 10 is viewed through the light-transmitting substrate 13), the light shielding material 18 that covers the interconnector 12 is provided. There is no unevenness on the surface, and it is possible to reliably prevent a decrease in design.

  The light shielding material 18 is formed so as to cover not only the interconnector 12 but also the entire bus bar electrodes 16 a of the two solar cells 10. Thereby, when the surface side of the photovoltaic cell 10 is seen through the translucent substrate 13, not only the interconnector 12, but also the bus bar electrode 16a (more precisely, the bus bar) which is the surface electrode 16 of the photovoltaic cell 10. The output lead wire 12a connected to the electrode 16a (including the output lead wire 12a) can also be concealed by the light shielding material 18, so that the solar cell module 1 having a more uniform appearance and excellent design can be provided.

  Here, the light shielding material 18 will be specifically described.

  The light shielding material 18 is formed in a strip shape over the entire length in the longitudinal direction (lateral direction in FIG. 1A) at a substantially central portion of the translucent substrate 13 in the short direction (vertical direction in FIG. 1A). The bus bar electrode 16a, the output lead wire 12a, and the interconnector 12 are formed to be slightly wider, for example, 4 mm. That is, the difference between the width of the bus bar electrode 16a (3 mm), the output lead wire 12a connected to the bus bar electrode 16a, the width of the interconnector 12 (2 mm), and the width of the light shielding material 18 (4 mm) is 1 to 2 mm or less. It is preferable to be at a level. By having such a dimensional relationship, the light shielding material 18 reliably hides the interconnector 12, the bus bar electrode 16a, and the output lead wire 12a, and the light shielding material 18 covers the surface of the solar cell 10 other than the bus bar electrode 16a. A decrease in power generation efficiency can be suppressed. Further, in the manufacturing process described later, when the solar battery cell 10 is disposed on the translucent substrate 13 via the sealing material 15, the interconnector 12, the bus bar electrode 16 a, and the light receiving surface 13 a side of the translucent substrate 13 are provided. The solar cell 10 and the translucent substrate 13 can be accurately aligned by arranging the output lead wire 12a so as to be invisible so as to be invisible to the light shielding material 18.

  Further, the light shielding material 18 is configured to have a portion whose width changes in the vicinity of both left and right end portions of the translucent substrate 13. That is, the left and right end portions 18b of the light shielding material 18 are formed to be wider than the central portion 18a. Specifically, the left and right end portions 18b are formed to have a width of 5.4 mm with respect to the 4 mm width of the central portion 18a, and the formation length is about 7 to 8 mm. Further, the step portion 18c whose width changes is formed on the R plane.

  Thus, by forming the light shielding material 18 so that the width changes in the vicinity of the end portion of the translucent substrate 13, the end of the solar battery cell 10 is based on the stepped portion 18 c where the width of the light shielding material 18 changes. By aligning the portions, accurate alignment in the longitudinal direction (left-right direction in FIG. 1A) of the interconnector 12, the bus bar electrode 16a, and the output lead wire 12a provided in the solar battery cell 10 can be easily performed. It becomes. And since the exact alignment with the photovoltaic cell 10 and the translucent board | substrate 13 is attained, the manufacturing tolerance can be made small, the reduction | decrease of the external dimension of the solar cell module 1, and the solar cell module accompanying this The conversion efficiency can be improved.

  Here, in the present embodiment, the light shielding material 18 is formed by applying an insulating paint to the surface of the translucent substrate 13. Specifically, it is formed by printing light-shielding ink (for example, heat-resistant black ink). Thereby, the electrode surface of the photovoltaic cell 10 (that is, the bus bar electrode 16a, the output lead wire 12a connected to the bus bar electrode 16a, and the surface of the interconnector 12) can be hidden by the light shielding material 18. In addition, by applying a coating material as the light shielding material 18 to the back surface (the surface opposite to the light receiving surface) 13b of the translucent substrate 13 by printing, it is not necessary to prepare another member such as a light shielding tape, thereby increasing productivity. improves. However, a light shielding tape can also be used.

  Further, when the translucent substrate 13 is formed of a resin such as polycarbonate, the light shielding material 18 may also be a colored resin. Thereby, the adhesiveness of the translucent board | substrate 13 and the light shielding material 18 improves, and adhesive strength can be ensured even in a high-temperature, high-humidity environment.

  Further, in the solar cell module 1 of the present embodiment, the sealing material 15 is interposed between the light shielding material 18 and the interconnector 12. Thereby, the unevenness | corrugation by the solder etc. which were coated on the surface of the interconnector 12, especially the projection part by a solder can be prevented from contacting the light shielding material 18. FIG. That is, it is possible to prevent the projections on the surface of the interconnector 12 from scratching the light shielding material 18 and causing the light shielding material 18 to be uneven when viewed from the light receiving surface 13 a side of the translucent substrate 13.

  Further, in the present embodiment, the color tone of the light shielding material 18 and the color tone of the surface of the solar battery cell 10 are approximated when the surface side of the solar battery cell 10 is viewed through the translucent substrate 13. ing. That is, the color of the light shielding material 18 is adjusted. Thereby, it can suppress that the light-shielding material 18 appears to protrude from the surface of the solar cell module 1, and can provide the external appearance with a unity feeling.

  Further, in the present embodiment, the color tone of the protection member 14 and the color tone of the surface of the solar battery cell 10 are approximated when the surface side of the solar battery cell 10 is viewed through the translucent substrate 13. ing. Thereby, the uniform external appearance can be provided to the entire solar cell module 1.

  Next, the manufacturing method of the solar cell module 1 having the above-described configuration will be described with reference to each process chart shown in FIGS. 5A to 5G. 5A is a plan view (viewed from the light receiving surface side), FIGS. 5B and 5C are bottom views (viewed from the surface opposite to the light receiving surface), and FIG. 5D is the light receiving surface side up. FIG. 5E is a plan view seen from the back surface 13b of the translucent substrate 13, and FIGS. 5F and 5G are cross-sectional views with the light receiving surface 13a side of the translucent substrate 13 facing down.

  In the manufacturing process 1 shown in FIG. 5A, the left side portion of the interconnector 12 coated with solder is opposed to the bus bar electrode 16a of the surface electrode 16 of the left solar cell 10 and subjected to heat and pressure treatment at 150 to 160 ° C. Connect with solder. Similarly, the output lead wire 12a is disposed opposite to the bus bar electrode 16a of the surface electrode 16 of the right solar battery cell 10, and is subjected to heat and pressure treatment at 150 to 160 ° C. for solder connection. In this embodiment, the width of the bus bar electrode 16a is 3 mm, the width of the interconnector 12 and the output lead wire 12a is 2 mm, and the interconnector 12 and the output lead wire 12a are respectively in the width direction from the bus bar electrode 16a. It is preferable to arrange and connect so as not to protrude.

  In the manufacturing process 2 shown in FIG. 5B, after the right side portion of the interconnector 12 is bent so as to be lowered by one step, the right side portion is disposed opposite to the back surface electrode 17 of the right solar cell 10 and heated at 150 to 160 ° C. Apply pressure treatment and solder.

  In the manufacturing process 3 shown in FIG. 5C, another output lead wire 12 b is disposed opposite to the back surface electrode 17 of the left solar cell 10 and subjected to heat and pressure treatment at 150 to 160 ° C. for solder connection. FIG. 5D is a cross-sectional view showing a connection state between the left solar cell 10 and the right solar cell 10 after the output lead wire 12b is connected in this manner.

  In the manufacturing process 4 shown in FIG. 5E, the light shielding material 18 is formed on the surface 13 b opposite to the light receiving surface of the translucent substrate 13. The formation position is a portion facing the interconnector 12 and the output lead wire 12a. Specifically, by printing or applying an insulating black ink or colored resin on the surface 13b opposite to the light receiving surface of the translucent substrate 13, the left and right end portions 18b are wider than the central portion 18a. A light shielding material 18 is formed. However, this manufacturing process 4 and the previous manufacturing processes 1 to 3 may be performed in parallel, or only the manufacturing process 4 may be performed in advance. By performing the manufacturing process 4 in parallel or in advance, the manufacturing time of the solar cell module 1 can be shortened.

  In the manufacturing process 5 shown in FIG. 5F, the light-transmitting sealing material 15 is placed on the light-transmitting substrate 13 on which the light shielding material 18 is formed, and the two series manufactured in the manufacturing process 3 are formed thereon. The solar battery cell 10 is placed with the surface side (surface electrode 16 and output lead wire 12a side) facing down. At this time, as described above, the alignment in the width direction is performed so that the interconnector 12, the bus bar electrode 16 a and the output lead wire 12 a of the solar battery cell 10 are on the light shielding material 18 of the translucent substrate 13. At the same time, the end of the solar battery cell 10 is aligned with the stepped portion 18c of the light shielding material 18 as a reference. Thereby, exact alignment of the width direction and longitudinal direction of the photovoltaic cell 10 and the translucent board | substrate 13 is attained easily.

  In the manufacturing process 6 shown to FIG. 5G, another sealing material 15 and the protection member (back sheet | seat) 14 are arrange | positioned in order on the photovoltaic cell 10 aligned in this way, and a lamination process is implemented. At this time, the protective member 14 is formed with an opening (notch) 14c for leading the output lead wire 12b to the outside. The opening 14c is arranged through the output lead wire 12b. By this laminating process, the sealing material 15 is melted by heat, and flows and seals so as to wrap the entire connection portion of the solar battery cell 10, the interconnector 12, and the output lead wires 12a and 12b. Here, as the sealing material 15, it is preferable to use a plastic material, specifically, a heat-welding resin material. By using a heat-welding resin material as the sealing material 15, the solar battery cell 10 can be easily and reliably sealed by a laminating process in which the sealing material 15 is simply heated while being pressurized. Moreover, as the protective member 14, a film having moisture resistance such as PET can be used, and the protective member 14 may have both a color tone and moisture resistance as a multilayer structure. Furthermore, it is good also as a thing of the 3 layer structure containing moisture-proof layers, such as PET / Al / PET (PET: polyethylene terephthalate).

  When the laminating step is thus completed, the solar cell module 1 of the present invention shown in FIGS. 1A to 1C is manufactured.

  In addition, in the said embodiment, although the solar cell module 1 of the structure which connected the two photovoltaic cells 10 is demonstrated, the number of connection of the photovoltaic cells 10 is not limited to two, and many solid series are connected. The present invention can also be applied to a large-sized (for example, 100 cm × 140 cm) solar cell module in which a plurality of connected solar cell strings are arranged in the horizontal direction and connected in series or in parallel to each other.

  That is, the embodiment disclosed this time is illustrative in all respects, and does not serve as a basis for limited interpretation.
