Description of the Invention: [Technical Field] The present invention relates to a method of packaging a battery, and more particularly to a method of packaging a dye-sensitized solar cell. [Prior Art] In general, a dye-sensitized solar cell is composed of an upper conductive glass substrate and a lower conductive glass substrate. The function of the upper conductive glass substrate is mainly 〇. The nano-sized titanium dioxide (Ti〇2) particles are dissolved in a solvent and uniformly coated on the upper conductive glass substrate to form a titanium dioxide layer. After heat treatment, a microscopic sponge-like, porous and large specific surface area film can be formed. This porous titanium oxide film is sensitized by a suitable dye to form a working electrode, which is a main photoelectric conversion member. Then, a metal catalyst layer such as platinum is applied to the lower conductive glass substrate to serve as a corresponding electrode. Finally, the upper conductive glass substrate, the lower conductive glass substrate and an electrolyte are assembled as a sandwich, and the titanium dioxide layer is illuminated to drive electrons to form a solar cell device. In the above manufacturing process, the upper conductive glass substrate and the lower conductive glass substrate generally use ITO or FTO transparent conductive glass as the substrate. However, the use of the above two substrates will be expensive, the substrate is not flexible, and the large-area fabrication is difficult. Too big and other issues. In addition, the organic packaging materials currently used are prone to deterioration and damage after long-term exposure to sunlight, and the commonly used packaging materials also have limitations that are not bendable. These are the bottlenecks that are currently not commercially viable for sensitized solar cells. 3 201044602 SUMMARY OF THE INVENTION In view of the above, the present invention provides a solar cell packaging method for packaging a flexible dye-sensitized solar cell. The present invention provides a method for packaging a dye-sensitized solar cell, comprising: providing a working electrode, an opposite electrode, and an isolation layer; combining the working electrode, the opposite electrode and the isolation layer, and arranging the isolation layer Between the working electrode and the opposite electrode; providing a soft encapsulating material, the soft encapsulating material is formed into a receiving space after the first hot pressing treatment; and the combined working electrode, the opposite electrode and the isolating layer are disposed And accommodating the space; filling an electrolyte into the accommodating space and discharging more gas; and performing a second hot pressing treatment to seal the accommodating space. In an embodiment of the invention, the hot pressing process is performed by a sealing machine. The flexible encapsulating material is one of the soft encapsulating materials described therein, wherein the working electrode comprises at least the titanium dioxide film disposed on the substrate in a transparent film in an embodiment of the invention. In an embodiment of the invention, the material resistant to attack by the organic solution is on a substrate and a titanium dioxide film in an embodiment of the invention. In summary, the use of a flexible encapsulating material provides a flexible shell and thus provides a flexible dye-sensitized solar cell. In addition, 4 201044602 provides a low-cost solar cell packaging technology through the hot pressing of the sealing machine. The above described features and advantages of the present invention will be more apparent from the following description. [Embodiment] Fig. 1 is a flow chart showing a packaging method of a dye-sensitized solar cell of the present invention, and Fig. 2 is a schematic view showing the combination of a dye-sensitized solar cell of the present invention. Referring to FIG. 1 and FIG. 2 respectively, the dye-sensitized solar cell 100 includes a working electrode 110, an opposite electrode 120, an isolation layer 130, an electrolyte (not shown), and a casing 140. In the method of packaging the dye-sensitized solar cell 100 of the present invention, the method includes the steps of: first providing a working electrode 110, an opposite electrode 120, and an isolation layer 130 (step S100). Thereafter, the working electrode 110, the opposite electrode 120 and the isolation layer 130 are combined, and the isolation layer 130 is disposed between the working electrode 110 and the opposite electrode 120 (step S200). The arrangement diagram can be referred to FIG. Disposed between the working electrode 110 and the opposite electrode 120 can be used to avoid the phenomenon that the opposite electrode 120 and the working electrode 110 are in contact with each other to cause a short circuit. It should be noted that the working electrode 110 of the dye-sensitized solar cell 100 may include at least one substrate and a titanium dioxide film disposed on the substrate, wherein the substrate may be a transparent conductive substrate or an opaque conductive substrate. Since the titanium dioxide film is disposed on the substrate, the 5 201044602 working electrode 110 can utilize the titanium dioxide film to absorb sunlight, perform photoelectric conversion, and convert the light energy into electrical energy. Thereafter, a soft encapsulating material is provided, and the soft encapsulating material is subjected to the first hot pressing treatment to form a receiving space (step S300). That is to say, in this step, a accommodating space is formed by first performing a hot pressing process around the three sides of the flexible packaging material through a soft packaging material, and the accommodating space can be used for accommodating the work of the dye sensitized solar cell 100. The electrode 110, the opposite electrode 120, the separation layer 130, and the electrolyte, and the soft enamel encapsulating material can constitute the housing 140 of the dye-sensitized solar cell 100. The soft encapsulating material described herein may be a transparent film or a material resistant to organic solution etching, such as plastic, and the hot pressing process may be performed through a mouth machine, for example, when the soft packaging material is a plastic. At the time, the plastic can be heat-pressed by a sealing machine to soften and close the three surrounding parts of the plastic. After that, the working electrode 110, the counter electrode 120 and the isolation layer 130 combined in step S200 are disposed in the accommodating space (step S400), and an electrolyte is filled into the accommodating space and more gas is discharged (step S500). And performing a second hot pressing process to seal the accommodation space (step S600). Similarly, the second hot pressing process referred to here is performed through a port machine. Because the soft packaging material is a plastic, the final opening of the plastic can be hot pressed by a sealing machine, and finally the dye is sensitive. The solar cell 100 is sealed in a flexible packaging material. 201044602 In addition, like the β-like battery, the working electrode HQ and the opposite electrode 120 can be electrically conducted through the electrolyte, which is naked, the dye-sensitized solar of the present invention, the electrolyte of the battery can be - containing secret liquid The electrical electrode and the opposite electrode are electrically connected to each other. The invention differs from the prior art in that the difference between the present invention and the prior art is that the material of the package and the packaging technology are as described in the prior art. Most of the organic packaging materials currently used are prone to deterioration after long-term exposure to sunlight. , damaged, and has an inflexible _. However, this method is proposed to be completely different. This package method uses a kind of soft sealing material through the sealing process of the sealing machine to seal the soft packaging material. Such a flexible encapsulating material can provide 140, so that it can be used for the dye-sensitized solar cell 100 of the double-body (four) κ, the secret type of flexible. Through the hot pressing of the sealing machine, the battery packaging technology can be used. For the purpose of providing a low-cost sun, although the previous examples of the present invention have been disclosed above, it is not intended to limit the invention, and any skilled artisan will do so without departing from the spirit and scope of the present invention. More moving fish moon 砰#丨彳^_, the equivalent replacement of the door decoration, is still within the scope of the patent protection of the invention.
