Sealing structure of Dye-Sensitized Solar Cell

The present invention relates to a sealing structure of a dye-sensitized solar cell, and more particularly, to a sealing structure of a dye-sensitized solar cell that firmly couples a positive electrode substrate and a negative electrode substrate so that an electrolyte does not leak to the outside in a dye-sensitized solar cell.

Dye-Sensitized Solar Cell (DSSC) is a solar cell developed by Michael Gratzel of the Swiss Federal Institute of Technology.It has lower manufacturing cost and energy efficiency compared to the existing silicon solar cell. It is high and can be manufactured to be transparent and bendable cell has the advantage that can be used in various applications.

Dye-sensitized solar cells serve as catalysts for photoelectrodes containing dye molecules for generating electron-hole pairs and semiconductor layers for transferring electrons, electrolytes for supplementing electrons with dye molecules, and redox reactions of electrolyte solutions. Made of a counter electrode coated with a platinum layer. When light is incident on the dye-sensitized solar cell, the dye that absorbs the light enters an excited state to send electrons to the conduction band of the semiconductor layer, and the transferred electrons flow along the electrode to an external circuit to transfer electrical energy. As it transfers electrical energy, it becomes a low energy state and moves to the counter electrode. The dye is supplied with electrons from the electrolyte solution as much as the number of electrons transferred to the semiconductor layer and returned to its original state. The electrolyte used serves to receive electrons from the counter electrode by a redox reaction and transfer them to the dye.

The photoelectrode serving as a negative electrode of a battery includes a semiconductor layer such as titanium dioxide (TiO 2 ), and a dye that absorbs light in the visible region and generates electron-hole pairs is adsorbed on the surface. Electrolyte supplying electrons to dye is I - / I 3 - consists of a reduced species, I - - oxidation as a source of ions LiI, NaI, alkaline ammonium iodide, imidazolium iodide, etc. are used, I 3 - ions to produce an I 2 melt in a solvent. The counter electrode is made of platinum or the like and serves as a catalyst for the ion redox reaction to provide electrons to ions in the electrolyte through a redox reaction on the surface.

Figure 1a shows a planar structure of the Z-type dye-sensitized solar cell module. 1A, a Z-type module 100 has a transparent cathode electrode 123 coated on a cathode substrate 120, and a semiconductor layer 121 formed on a transparent cathode electrode 123. Each unit cell is connected in series by an electrode connector 122, and protective layers 124 are formed on both sides of the electrode connector 122 to prevent oxidation by an electrolyte. The protective layer 124 is disposed between the positive electrode substrate 110 and the negative electrode substrate 120 to simultaneously seal the electrolyte filled in each unit cell. FIG. 1B is a cross-sectional view taken along the line A-A 'in FIG. 1A (modified etching position). Referring to FIG. 1B, unit cells separated by a protective layer 124 are formed in a space between the negative electrode substrate 120 and the positive electrode substrate 110. A transparent negative electrode 123 is formed on the negative electrode substrate 120. A transparent negative electrode etch unit 123a is periodically formed to electrically separate each unit cell electrode. The semiconductor layer 121 is formed on the transparent negative electrode 123, and the transparent positive electrode 111 and the platinum layer 112 are sequentially stacked on the positive electrode substrate 110, and the electrolyte 125 is filled therebetween. . A transparent positive electrode etching portion 111a for electrical separation is formed in the middle of the transparent positive electrode 111 as well. The transparent positive electrode 111 and the transparent negative electrode 123 of the neighboring unit cell are connected by an electrode connection part 122, and protective layers 124 are formed on both sides of the electrode connection part 122, and the amount of modules At the end, the positive electrode terminal 116 and the negative electrode terminal 126 are formed on the positive electrode substrate 110 and the negative electrode substrate 120, respectively.

In the dye-sensitized solar cell or module-type dye-sensitized solar cell composed of unit cells, electrode terminals for connecting to an external junction box are formed on a substrate, and the electrode terminals are sealed to prevent corrosion due to exposure to the electrolyte. A layer is applied to a part of the electrode terminal. A conventional sealing structure for preventing corrosion of an electrode terminal while preventing leakage of an electrolyte will be described with reference to FIGS. 3 to 4.

3 illustrates a sealing structure applied to a conventional dye-sensitized solar cell. Referring to FIG. 3A, in the dye-sensitized solar cell 200, a positive electrode substrate 210 and a negative electrode substrate 220 are coupled to face each other, and an upper portion of the positive electrode substrate 210 and a lower portion of the negative electrode substrate are connected. The positive electrode terminal 216 and the negative electrode terminal 226 are formed in opposite directions, respectively. The positive electrode grid 216a and the negative electrode grid 226a are connected to the positive electrode terminal 216 and the negative electrode terminal 226, respectively. The positive electrode grid 216a and the negative electrode grid 226a may be formed at overlapping positions on the positive electrode substrate and the negative electrode substrate which are coupled to each other, but in the drawing, the positive electrode grid and the negative electrode grid are shown as being spaced apart to be seen separately (FIG. In (b) of FIG. 3, the connection parts on the left and right sides are omitted to illustrate that the positive electrode grid and the negative electrode grid overlap. In addition, in the drawings, components such as a transparent electrode layer, a semiconductor layer, and a dye that may be included in the dye-sensitized solar cell are omitted. Referring to FIG. 3B, the sealing layer 230 is formed to apply one side of the positive electrode terminal 216 and the negative electrode terminal 226 formed on the positive electrode substrate 210 and the negative electrode substrate 220, respectively. The sealing layer is formed on the upper side and the lower side of the substrate in addition to one side of the positive electrode terminal 216 and the negative electrode terminal 226 so that the electrolyte between the substrates does not leak to the outside. The sealing layer is a layer disposed in the space between the positive electrode substrate and the negative electrode substrate, but in the drawings, the positive electrode substrate and the negative electrode substrate are illustrated as being positioned on the same surface for convenience of description. In addition, since it is necessary to protect the electrode grid extending from the positive electrode terminal and the negative electrode terminal from the electrolyte, a protective layer should be formed on the side of the electrode grid with the same material or a different material as the sealing agent, but the illustration thereof is omitted.

FIG. 4 is a cross-sectional view of a portion A-A 'of FIG. 3 to explain a cross section of a sealing part of a sealing structure applied to a conventional dye-sensitized solar cell. Referring to FIG. 4, the negative electrode substrate 220, the transparent negative electrode 222, the negative electrode terminal 226, and the sealing layer 230 are sequentially formed. The upper portion of the sealing layer 230 is coupled to the positive electrode substrate, but for convenience of description, the upper portion of the sealing layer is not shown. In the conventional sealing structure of the dye-sensitized solar cell, the sealing layer is formed on the negative electrode terminal or the positive electrode terminal. Typically, the electrode terminals are formed by firing silver (Ag) paste, so that the electrode is made of a metal material, and the sealing layer is made of a glass material such as glass frit or a polymer resin such as a photocurable polymer resin. Therefore, when the bonding force between the electrode terminal and the material constituting the sealing layer is weak, there is a high possibility that the sealing layer can be separated from the electrode terminal by external impact. In particular, since the electrode terminal is formed by sintering metal particles in the paste, the electrode terminal has a structure in which pores are contained therein, and thus has a structure with weak physical strength. Therefore, when a problem such as cracking occurs in the material constituting the electrode terminal due to external impact, the sealing layer may be destroyed together.

Prior art regarding the sealing structure of a dye-sensitized solar cell is disclosed in Korea Patent Publication No. 2010-0106837. The prior art comprises the steps of forming a glass frit rim layer on top of the transparent substrate and manufacturing a cathode electrode, forming a glass frit rim layer on top of the transparent substrate and manufacturing an anode electrode; A method of manufacturing a dye-sensitized solar cell including but not limited to forming an adhesive polymer layer on a glass frit edge on both electrodes and then bonding the two electrodes after opposing the anode-based electrode is disclosed. There is no specific configuration for improving the stability.

Accordingly, an object of the present invention is to provide a sealing structure of a dye-sensitized solar cell that can prevent the sealing layer from being separated from the substrate by physical impact by improving the bonding force between the sealing layer of the dye-sensitized solar cell and the substrate. It is.

In order to achieve the above object, the present invention provides a positive electrode substrate having a positive electrode terminal and a negative electrode substrate having a negative electrode terminal, an electrolyte filled between the positive electrode substrate and the negative electrode substrate, and a positive electrode substrate so that the filled electrolyte does not leak out. And a sealing layer which seals the cathode substrate by bonding, and the sealing layer is formed to apply one side of the positive electrode terminal and the negative electrode terminal so that the positive electrode terminal and the negative electrode terminal are not exposed to the electrolyte, and the positive electrode terminal to which the sealing layer is coated. And at one side of the negative electrode terminal provides a sealing structure of the dye-sensitized solar cell, characterized in that formed in the pattern portion is removed from the material forming the terminal.

According to one embodiment of the present invention, a transparent positive electrode and a transparent negative electrode are formed under the positive electrode terminal and the negative electrode terminal, respectively, and the transparent positive electrode and the transparent negative electrode may be removed under the pattern portion.

The sealing structure of the dye-sensitized solar cell of the present invention, since the material forming the terminal is removed from one side of the positive electrode terminal or negative electrode terminal to which the sealing layer is applied, the sealing layer includes a portion in direct contact with the transparent electrode or the substrate; have. Therefore, when the sealing layer is made of the same or similar material as that of the substrate, the bonding force between the sealing layer and the substrate can be improved, and the physical strength of the electrode terminal having a structure in which pores are formed is weak, so that the sealing layer is separated from the electrode terminal. The problem of separation can also be solved.

Hereinafter, the present invention will be described in detail.

The sealing structure of the dye-sensitized solar cell of the present invention includes a positive electrode substrate having a positive electrode terminal and a negative electrode substrate having a negative electrode terminal, an electrolyte filled between the positive electrode substrate and the negative electrode substrate, and a positive electrode so that the filled electrolyte does not leak out. And a sealing layer which seals the substrate and the negative electrode substrate, and the sealing layer is formed to apply one side of the positive electrode terminal and the negative electrode terminal so that the positive electrode terminal and the negative electrode terminal are not exposed to the electrolyte, and the positive electrode to which the sealing layer is coated. One side of the terminal and the negative electrode terminal is characterized in that the pattern portion is removed from the material forming the terminal.

The sealing structure used in the conventional dye-sensitized solar cell has a structure in which a sealing layer is formed to apply one side of the positive electrode terminal and the negative electrode terminal so that the material constituting the electrode terminal is not exposed to the electrolyte. However, such a conventional sealing structure has a relatively weak coupling force between the sealing layer and the electrode terminal because the sealing layer is applied on the electrode terminal, and because the electrode terminal has a structure in which pores are formed therein, the physical strength is weak. There was a possibility that the sealing layer was separated from the substrate by the impact. In the present invention, by removing and patterning a portion of the electrode terminal to which the sealing layer was applied, the sealing layer is in direct contact with the transparent electrode or the substrate to improve the physical bonding strength of the sealing layer. Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

5 shows a sealing structure of a dye-sensitized solar cell according to an embodiment of the present invention. Referring to FIG. 5, a negative electrode terminal 226 is formed on the negative electrode substrate 220, and a sealing layer 230 is formed while applying one side of the negative electrode terminal 226, and overlaps the sealing layer 230. A portion of the negative electrode terminal 226 of the portion is removed to form the negative electrode terminal pattern portion 240. The sealing layer 230 is formed while coating one side of the negative electrode terminal in order to prevent corrosion of the negative electrode terminal by the electrolyte and to increase the effective power generation area of the dye-sensitized solar cell. This is because when the sealing layer is spaced apart from the negative electrode terminal in the inward direction, the area in which the electrolyte is filled is reduced, thereby reducing the effective power generation area. In the drawings, for convenience of description, a transparent negative electrode, a semiconductor layer, and the like are not shown, and only the negative electrode terminal and the sealing layer formed on the negative electrode substrate are illustrated, but the sealing structure having the same structure may be applied to the positive electrode terminal formed on the positive electrode substrate. In addition, although the protective layer for protecting the electrode grid from the electrolyte is not shown in the figure, the protective layer of the same material or different material as the sealing layer may be formed on the side and top of the electrode grid. The sealing structure of the dye-sensitized solar cell of the present invention can be applied not only to the structure in which the electrode grid is formed but also to the structure in which the electrode grid is not formed, and also to the module in which a plurality of unit cells are connected in series or in parallel. Can be.

FIG. 6 illustrates a part of a cross-sectional view taken along the line B-B 'of FIG. 5 to explain a cross-sectional structure applied to a sealing structure of a dye-sensitized solar cell according to an embodiment of the present invention. Referring to FIG. 6A, a transparent negative electrode 222 is formed on the negative electrode substrate 220, and a negative electrode terminal 226 is formed on the transparent negative electrode 222 in a patterned form, and the negative electrode terminal 226 is formed. And the sealing layer 230 is formed on the transparent negative electrode 222. Patterning a part of the negative electrode terminal can be simply performed using a screen printing mask covering the patterned portion of the negative electrode terminal. The negative electrode substrate 220 may be made of a glass substrate or a transparent polymer resin substrate, and the transparent negative electrode may be made of a metal oxide such as indium tin oxide (ITO) or fluorine-doped tin oxide (FTO). The negative electrode terminal may be formed by firing silver (Ag) paste, and the sealing layer may be made of a glass resin such as glass frit or a polymer resin such as a photocurable resin. In the structure shown in the figure, a part of the sealing layer 230 is in contact with the negative electrode terminal 226, and a part is in contact with the transparent negative electrode 222. The negative electrode terminal 226 is formed by firing a paste containing silver (Ag) particles and a binder. Since the firing temperature is much lower than the melting point of silver, the negative electrode terminal has pores formed therein, resulting in a weak physical strength. Therefore, when the portion of the electrode terminal is patterned like the sealing structure of the dye-sensitized solar cell of the present invention to increase the area where the electrode terminal is in direct contact with the transparent electrode or the substrate, the stability of the sealing portion can be improved. Referring to FIG. 6B, the transparent negative electrode 222, the negative electrode terminal 226, and the sealing layer 230 are sequentially formed on the negative electrode substrate 220, and the transparent negative electrode 222 and the negative electrode terminal 226 are sequentially formed. ) Is patterned in a partially removed form. The negative electrode substrate 220 is exposed and the sealing layer 230 is in contact with the patterned portions of the transparent negative electrode 222 and the negative electrode terminal 226. In such a structure, if the material of the sealing layer is selected in consideration of the material of the negative electrode substrate, the sealing layer can be more firmly bonded to the substrate. That is, when the substrate is a glass substrate, the material of the sealing layer is selected to be glassy like glass frit, or when the substrate is a polymer resin substrate, the material of the sealing layer is selected as the polymer resin. Physical bond strength can be improved. A laser may be used to partially remove and pattern the transparent negative electrode. When the laser is irradiated to a portion to remove the transparent negative electrode, the lower negative electrode may be removed and the lower substrate may be exposed. In the drawings, the sealing layer is formed on the negative electrode substrate in order to realize the sealing structure of the dye-sensitized solar cell of the present invention, but the method of forming the sealing layer on the positive electrode substrate is also possible. That is, when the positive electrode terminal and the negative electrode terminal (or including the transparent positive electrode and the transparent negative electrode at the bottom) is patterned, the sealing layer is formed on either the positive or negative substrate, and then the two substrates are bonded to each other. The sealing structure may be implemented in the same structure as the substrate.

7 illustrates a shape of a terminal pattern portion which may be applied to a sealing structure of a dye-sensitized solar cell according to an embodiment of the present invention. Referring to FIG. 7A, a plurality of negative electrode terminal pattern parts 240a to 240d are formed on the negative electrode terminal 226 formed on the negative electrode substrate 220. The shape of the negative electrode terminal pattern parts 240a to 240d may be variously modified, such as a rectangle, a circle, and an oval, and the number of formation may also be variously selected. Referring to FIG. 7B, one negative electrode terminal pattern part 240 ′ long in the longitudinal direction of the terminal is formed on the negative electrode terminal 226 formed on the negative electrode substrate 220. As such, when the negative electrode terminal pattern part 240 ′ is formed, a contact area between the sealing layer and the transparent electrode or the sealing layer and the substrate may be increased to improve the bonding force of the sealing portion.

The electrode terminal of the solar cell is a part which draws out the electric charge generated by light to the outside and outputs it. Junction box is generally connected to the electrode terminal of the solar cell, it is advantageous that the positive electrode terminal and the negative electrode terminal is formed adjacent to the junction box. If the positive electrode terminal and the negative electrode terminal are formed in different directions, the wires must be extended to connect the junction box, which may damage the appearance of the product. According to an embodiment of the present invention, the positive electrode terminal and the negative electrode terminal of the dye-sensitized solar cell may be formed in one direction on the substrate.

8 illustrates an electrode terminal of a dye-sensitized solar cell in which a positive electrode terminal and a negative electrode terminal are formed in one direction on a substrate according to an embodiment of the present invention. In FIG. 8, for convenience of description, the positive electrode substrate and the negative electrode substrate are not distinguished from each other, and only the positive electrode formed on the positive electrode substrate and the negative electrode formed on the negative electrode substrate are illustrated. Referring to FIG. 8, the positive electrode terminal 216 to which the positive electrode grids are connected is formed on the right side, and the negative electrode terminal 222 to which the negative electrode grids are connected is formed on the left side, the positive electrode terminal 216 and the negative electrode terminal 226. The positive electrode terminal pattern portion 250 and the negative electrode terminal pattern portion 240 are respectively formed in FIG. At this time, the negative electrode terminal 226 extends from the top to the right to form a negative electrode junction box connection portion 226b on the right outer side of the substrate. In this structure, since the positive electrode terminal 216 and the negative electrode junction box connecting portion 226b are formed adjacent to each other, it is easy to connect the external junction box. Although not shown in the drawing, the sealing layer may be formed at a position including the positive electrode terminal pattern part 250 and the negative electrode terminal pattern part 240 to firmly seal the sealing part in the same manner as described with reference to FIGS. 5 and 6.
