Description

  The present invention relates to a method for manufacturing a dye-sensitized solar cell to which a printing method is applied, and an apparatus for manufacturing a dye-sensitized solar cell.

  At present, some solar cells and thin film silicon solar cells using a crystalline silicon substrate are beginning to be put into practical use. However, the former has a problem that the manufacturing cost of the silicon substrate is high. The latter has a problem that the manufacturing cost increases because it is necessary to use various semiconductor manufacturing gases and complicated apparatuses. For this reason, efforts are being made to reduce the cost per power generation output by increasing the efficiency of photoelectric conversion in any solar cell. However, the above problem has not been completely solved.

  As a new type of solar cell, a dye-sensitized solar cell applying photo-induced electron transfer of a metal complex is disclosed in Patent Document 1 (Japanese Patent No. 2664194). In this dye-sensitized solar cell, a photoelectric conversion layer, which is a metal oxide semiconductor layer on which a dye is adsorbed, and an electrolyte layer are disposed between electrodes formed on two glass substrates, respectively, and absorbs in the visible light region. Has a spectrum.

  In this dye-sensitized solar cell, electrons are generated when the photoelectric conversion layer is irradiated with light, and the electrons move to the electrodes. The electrons that have moved to the electrode move to the electrolyte layer through the opposing electrode through the external electric circuit, and are carried by the ions in the electrolyte to return to the photoelectric conversion layer. In this way, electric energy is extracted.

  Such a dye-sensitized solar cell can employ a simple and inexpensive manufacturing process such as a printing method, all or part of the manufacturing process, and thus a solar cell and a thin film silicon using a crystalline silicon substrate Compared to solar cells, it can be manufactured at a very low cost.

  In addition, as shown in FIG. 8, a dye-sensitized solar cell module in which a plurality of photoelectric conversion elements are connected in series is disclosed in Patent Document 2 (Japanese Patent Laid-Open No. 2001-357897) described below as a basic operation as described above. Has been proposed in

  As a specific structure, a photoelectric conversion layer 104 made of a titanium oxide layer on which a dye is adsorbed is formed on a glass substrate 101 on which a transparent conductive film (collecting electrode) 105 patterned in a strip shape is formed. On the other glass substrate 102, the counter electrode 103 is formed by dividing the platinum layer into strips.

  The two glass substrates 101 and 102 are bonded together, an electrolytic solution to be the carrier transport layer 106 is injected between the glass substrates 101 and 102, and the outer periphery between the glass substrates 101 and 102 is sealed with a resin. By the above manufacturing method, the dye-sensitized solar cell module which has a some photoelectric conversion element on the same board | substrate is produced.

  In this dye-sensitized solar cell module, a current collecting electrode 105 of one photoelectric conversion element and a counter electrode 103 of another adjacent photoelectric conversion element are electrically connected by a conductive connection layer 108 sandwiched between sealing means 107. By being connected, each photoelectric conversion element is connected in series. In order to prevent the conductive connection layer 108 from coming into contact with the electrolytic solution, insulating protective layers 107 are formed on both sides of the conductive connection layer 108 between adjacent photoelectric conversion elements.

  In addition to the above, solar cells having various structures have been proposed. In any structure, patterns of different materials are adjacent to each other in the horizontal direction of the substrate and stacked in the vertical direction of the substrate. Only when a pattern can be formed in a simple structure, low-cost manufacturing by a printing method can be realized.

  Generally, screen printing, intaglio printing, etc. are mentioned as a method of forming a pattern by a printing method. However, intaglio offset printing is attracting attention for the reasons that it is possible to form a fine pattern, to increase the area of the substrate, and to print even on a rigid substrate. .

  In the following Patent Document 3 (Japanese Patent Laid-Open No. 8-306399), manufacturing of a photochemical battery can be performed at a low cost in a short time by forming each layer in a continuous manufacturing process using an offset printer. It is described. In addition, when forming an insulating layer between adjacent cells, the insulating layer is laminated and printed to obtain an insulating layer with a desired thickness, and adjacent layers in the same cell are sequentially printed. The technology to form is described.

Japanese Patent No. 2664194 JP 2001-357897 A JP-A-8-306399

  However, in the current printing method, the pattern position accuracy and pattern shape accuracy are not as high as pattern formation by photolithography. That is, after printing a certain pattern, when a different pattern is printed at a position that is relatively apart from the pattern by a certain distance, a pattern having a desired shape is not formed at a desired position.

  When the present inventors performed the contents described in Patent Document 3, when different layers were formed adjacent to each other, gaps were formed between the patterns where the adjacent patterns should be arranged without gaps. Further, in the printing method, each layer is formed using fluid ink, so if the upper layer is stacked with a gap, the upper layer ink flows into the lower layer through the gap.

  When applying the printing method to the manufacture of dye-sensitized solar cells, the ink in the upper layer flows into the lower layer through the gaps between the patterns, and an unintended leak path is formed between the upper layer and the lower layer. Cause.

  On the other hand, it is possible to prevent a gap between patterns by forming a part of adjacent patterns so as to overlap each other. However, when the printed pattern is brought into contact with the film in an undried state, different materials diffuse and mix at the pattern bonding interface, thereby deteriorating device characteristics.

  Further, by inserting a drying and firing step between adjacent pattern printings, diffusion and mixing of different materials at the above-described pattern bonding interface can be suppressed. However, the tact time is remarkably increased due to an increase in the manufacturing process.

  That is, according to the conventional method, the adjacent pattern cannot be formed on the substrate without a gap and with a short tact time (high tact time).

The same parts and corresponding parts are denoted by the same reference numerals, and redundant description may not be repeated.

(Embodiment 1)
(Basics of dye-sensitized solar cell manufacturing method)
A preferred embodiment of the dye-sensitized solar cell of the present invention will be described with reference to the drawings. The dye-sensitized solar cell has a configuration in which a plurality of adjacent layers are stacked. First, for basic understanding, a method for manufacturing a dye-sensitized solar cell will be described using the schematic structure shown in FIG.

  The pattern group 4 shown in FIG. 1 is a cross-sectional view of a pattern in which a plurality of patterns extending on a line in the depth direction of the paper are stacked.

<Pattern formation method>
Here, a pattern forming method using an intaglio offset printing machine common to the first manufacturing method and the second manufacturing method described below will be described with reference to FIG. The intaglio offset printing machine 10 mainly includes a printing plate 11, an ink application unit 12, a transfer plate 13, and a substrate transport unit 2.

  The ink 20 is applied from the ink application unit 12 to the printing plate 11, and the ink layer 19 is formed only on the concave portion 18 of the printing plate 11 by scratching with the doctor blade 14. The printing plate 11 and the transfer plate 13 are rotated and brought into close contact at the contact point 21. As a result, the ink layer 19 of the printing plate 11 is transferred onto the transfer plate 13 to form a pattern 15 on the transfer plate.

  Subsequently, the transfer plate 13 rotates and is brought into close contact with the substrate 3 at the contact point 22. As a result, the pattern 15 on the transfer plate is transferred onto the substrate 3 to form the pattern 16 on the substrate.

  The material used for the transfer plate 13 is not particularly limited as long as it is resistant to the ink 20 and can be transferred from the printing plate 11 and subsequently transferred to the substrate 3. As such a material, a silicone resin, a fluorine compound resin, or the like is preferable.

  The manufacturing apparatus 1A includes a printing unit group a and a printing unit group b. Although not shown, the printing unit group c and the printing unit group d have the same configuration as the printing unit group a and the printing unit group b. Yes. For convenience of explanation, FIG. 3 shows only the printing unit group a and the printing unit b.

  The printing unit group a includes a printing unit a1, a printing unit a2, and a pressurizing unit Pa. Although not shown, the printing unit group a includes a printing unit a3, a printing unit a4,... Having the same configuration as the printing unit a1 and the printing unit a2.

  The printing unit a1 includes a printing plate a1-1, an ink application unit a1-2 for supplying ink to the printing plate a1-1, and a transfer plate a1-3. The printing unit a2 includes a printing plate a2-1, ink application means a2-2 for supplying ink to the printing plate a2-1, and a transfer plate a2-3.

The printing unit b2 includes a printing plate b2-1, an ink application unit b2-2 that supplies ink to the printing plate b2-1, and a transfer plate b2-3.

<Method for producing dye-sensitized solar cell>
Next, a method for manufacturing the dye-sensitized solar cell shown in FIG. 1 using the manufacturing apparatus shown in FIG. 3 will be described.

  Schematically, the adjacent pattern group A is formed on the substrate 3 using the printing unit group a. Next, the adjacent pattern group B is laminated on the adjacent pattern group A using the printing unit group b. Further, the adjacent pattern group C is stacked on the adjacent pattern group B using the printing unit group c. Similarly, adjacent pattern groups D,... Are sequentially stacked.

  For example, in the case of the adjacent pattern group A, the pattern A1 is formed using the printing unit a1, the pattern A2 is formed using the printing unit a2, and the patterns A3, A4,. • Form.

  Here, as shown in FIG. 4, the printing unit a <b> 1 and the printing unit A <b> 2 are arranged so that the pattern A <b> 2 is shifted from the pattern A <b> 1 by XA <b> 1 in the substrate transport direction (direction shown by the arrow 5 in FIG. 3). a2, the substrate transfer means 2 is controlled. The pattern A3 controls the printing unit a2, the printing unit a3, and the substrate transporting unit so that the pattern A3 is disposed at a position shifted by XA2 in the substrate transporting direction with respect to the pattern A2. Thereafter, similar processing is performed to form an adjacent pattern group A in which the patterns A1, A2, A3, A4,... Are arranged with XA1, XA2, XA3,.

  Thereafter, after an appropriate drying process, the adjacent pattern group A is pressed by the pressurizing means Pa. Specifically, the roller Pa is pressed in the direction perpendicular to the substrate so as to include all or part of the adjacent pattern. As a result, the adjacent patterns are stretched in the horizontal direction of the substrate, and the gaps XA1, XA2,... Between the patterns are all filled, and the adjacent laminated pattern group filled with no gaps between the patterns is completed.

  For the gap, the pattern distortion amount L in the horizontal direction when the substrate is pressurized in advance with a predetermined pressure is measured and set based on this. For example, as shown in FIGS. 5A and 5B, in the case of XA1, when the pre-pressing patterns A1 and A2 are pressed, the substrate contracts in the vertical direction according to the Poisson's ratio of the ink, and the substrate horizontal Stretch in the direction. As a result, the patterns A1 'and A2' are deformed. The stretching amount in the horizontal direction of the substrate is set so that 0 <XA1 <LA1 + LA2 if the pattern A1 is LA1 and the pattern A2 is LA2.

  The same process is performed on the adjacent pattern groups B, C,... To complete the pattern group 4 (see FIG. 1).

  Thus, according to the 1st manufacturing method of the dye-sensitized solar cell using the manufacturing apparatus 1A, it is an adjacent pattern in the stage transferred from the printing plate to the transfer plate, and the stage transferred from the transfer plate onto the substrate. Adjacent patterns come into contact with each other for the first time by pressurization by the pressurizing means Pa without contacting each other. At the time of contact by pressurization, the ink is dried to such an extent that the material is not mixed, so there is no material diffusion / mixing at the joint interface. Then, by drying and baking the formed adjacent patterns in a lump, the adjacent patterns can be formed on the substrate with a short tact time (high tact time) without gaps.

  In addition, although the example which presses with a pressurizing means every time it forms 1 layer of adjacent pattern groups here was shown, after laminating | stacking an adjacent pattern group in multiple times according to the film thickness of a required adjacent pattern group, You may press by a pressurizing means.

  The surface of the pressurizing means is desirably a material having high ink releasability, specifically, a silicone resin or a fluorine compound resin. Furthermore, the solubility of the solid component in the ink constituting the pattern in the solvent in the ink is desirably larger than the solubility in the solvent in the ink constituting the adjacent pattern and the laminated pattern of the pattern. Thus, when the pattern is brought into contact with pressure, material diffusion and mixing at the bonding interface can be further suppressed.

<Method for producing dye-sensitized solar cell>
Next, a method for producing the dye-sensitized solar cell of FIG. 1 will be described using the apparatus of FIG.

  Schematically, the adjacent pattern group A is formed on the substrate 3 using the printing unit group a. Next, the adjacent pattern group B is laminated on the adjacent pattern group A using the printing unit group b. Further, the adjacent pattern group C is stacked on the adjacent pattern group B using the printing unit group c. Similarly, adjacent pattern groups D,... Are sequentially stacked.

  For example, in the case of the adjacent pattern group A, the printing unit a1 is used to form the pattern A1 on the transfer plate aa, and the printing unit a2 is used to form the pattern A2 on the transfer plate aa. Then, patterns A3, A4,... Are formed on the transfer plate aa. The pattern printed on the transfer plate aa is transferred to the substrate 3.

  Here, referring to FIG. 4 again, the pattern A2 is printed at a position shifted from the pattern A1 by XA1 in the substrate transport direction (direction indicated by the arrow 5 in FIG. 6). The unit a2 and the substrate transfer means are controlled. The pattern A3 controls the printing unit a2, the printing unit a3, and the substrate transporting unit so that the pattern A3 is disposed at a position shifted by XA2 in the substrate transporting direction with respect to the pattern A2. Thereafter, similar processing is performed to form an adjacent pattern group A in which the patterns A1, A2, A3, A4,... Are arranged with XA1, XA2, XA3,.

  Thereafter, after an appropriate drying process, the adjacent pattern group A is pressed by the pressurizing means Pa. Specifically, the roller Pa is pressed in the direction perpendicular to the substrate so as to include all or part of the adjacent pattern. As a result, the adjacent patterns are stretched in the horizontal direction of the substrate, and the gaps XA1, XA2,... Between the patterns are all filled, and the adjacent laminated pattern group filled with no gaps between the patterns is completed.

  For the gap, the pattern distortion amount L in the horizontal direction of the substrate when it is pressurized in advance with a predetermined pressure is measured and set based on this. For example, as shown in FIGS. 5A and 5B, in the case of XA1, when the pre-pressing patterns A1 and A2 are pressed, the substrate contracts in the vertical direction according to the Poisson's ratio of the ink, and the substrate horizontal Stretch in the direction. As a result, the patterns A1 'and A2' are deformed. The stretching amount in the horizontal direction of the substrate is set so that 0 <XA1 <LA1 + LA2 if the pattern A1 is LA1 and the pattern A2 is LA2.

  The pattern group 4 is completed by performing the same processing for the adjacent pattern groups B, C,.

  As described above, even in the second method for manufacturing a dye-sensitized solar cell using the manufacturing apparatus 1B, the adjacent pattern is not transferred at the stage of transfer from the printing plate to the transfer plate and from the transfer plate to the substrate. Contact for the first time by pressurization without contact. At the time of contact by pressurization, the ink is dried to such an extent that the material is not mixed, so there is no material diffusion / mixing at the joint interface. Then, by drying and baking the formed adjacent patterns in a lump, the adjacent patterns can be formed on the substrate with a short tact time (high tact time) without gaps.

  Here, in the first manufacturing method, a transfer plate is individually provided for each printing plate. However, the second manufacturing method is different in that a common transfer plate is provided for a plurality of printing plates. In the first manufacturing method, for example, when two layers of adjacent patterns are formed, it is necessary to control the relative operations of the two printing plates, the two transfer plates, and the substrate. Control of the relative operation of the printing plate, one transfer plate, and the substrate is sufficient, and since the number of combinations of members to be controlled is small, the pattern position accuracy is superior to the first manufacturing method. In addition, as the number of transfer plates decreases, the apparatus footprint also decreases.

  In addition, although the example which presses with a pressurizing means every time it forms 1 layer of adjacent pattern groups here was shown, after laminating | stacking an adjacent pattern group in multiple times according to the film thickness of a required adjacent pattern group, You may press by a pressurizing means.

  The surface of the pressurizing means is desirably a material having high ink releasability, specifically, a silicone resin or a fluorine compound resin.

  Furthermore, the solubility of the solid component in the ink constituting the pattern in the solvent in the ink is desirably larger than the solubility in the solvent in the ink constituting the adjacent pattern and the laminated pattern of the pattern. Thus, when the pattern is brought into contact with pressure, material diffusion and mixing at the bonding interface can be further suppressed.

The dye-sensitized solar cell in the present embodiment has a conductive layer, a photoelectric conversion layer in which a dye is adsorbed on a porous semiconductor layer, a carrier transport layer, a catalyst layer, and a counter electrode conductive material on a support made of a light-transmitting material.

A dye-sensitized solar cell module is produced by connecting two or more dye-sensitized solar cells 100 in series.

  The dye-sensitized solar cell 100 according to the present embodiment includes an adjacent pattern group A composed of a sealing material 38 / a photoelectric conversion layer 33 / a sealing material 38, and a sealing material 38 / a catalyst layer 35 / a sealing material 38.

Example 1

  An adjacent pattern group A composed of glass paste / titanium oxide film / glass paste was formed on the conductive layer of the glass substrate using the first manufacturing method. Here, the pattern interval of the glass paste / titanium oxide film was set to about 1% of the pattern width of the glass paste. The formed adjacent pattern group A was pressed with a roller so that the printing pressure was 30 kPa. As a result, the adjacent pattern group A in which the gaps between the patterns were completely filled was obtained.

  Next, adjacent pattern group B composed of glass paste / platinum film / glass paste was formed on adjacent pattern group A using the first manufacturing method. Here, the pattern interval of the glass paste / platinum film was set to be about 1% of the pattern width of the glass paste. The formed adjacent pattern group B was pressed with a roller so that the printing pressure was 30 kPa. As a result, an adjacent pattern group B in which the gaps between the patterns were completely filled was obtained.

  Next, adjacent pattern group C composed of glass paste / carbon film / glass paste was formed on adjacent pattern group B using the first manufacturing method. Here, the pattern interval of the glass paste / carbon film was set to be about 1% of the pattern width of the glass paste. The formed adjacent pattern group C was pressed with a roller so that the printing pressure was 30 kPa. As a result, an adjacent pattern group C in which the gaps between the patterns were completely filled was obtained. Subsequently, the adjacent pattern group was fired using a firing furnace.

  The adjacent pattern group was formed as described above and immersed in a dye solution, and the dye was adsorbed on the porous semiconductor layer to obtain a photoelectric conversion layer. As the extraction electrode, a titanium plate provided with an electrolyte solution inlet was used. Thereafter, an electrolytic solution was injected from the electrolytic solution injection port of the extraction electrode using the capillary effect. Finally, the dye-sensitized solar cell was completed by sealing the electrolyte injection port.

  In the dye-sensitized solar cell manufactured in this way, there was no gap between adjacent patterns that existed in the conventional printing method, and the adjacent pattern could be formed without gaps.

(Example 2)
The production of the dye-sensitized solar cell using the second production method will be described below. First, a glass substrate in which a conductive layer made of a tin oxide film was formed on a support made of glass was used as the substrate.

  An adjacent pattern group A composed of glass paste / titanium oxide film / glass paste was formed on the conductive layer of the glass substrate using the second manufacturing method. Here, the pattern interval of the glass paste / titanium oxide film was set to about 1% of the pattern width of the glass paste. The formed adjacent pattern group A was pressed with a roller so that the printing pressure was 30 kPa. As a result, the adjacent pattern group A in which the gaps between the patterns were completely filled was obtained.

  Next, adjacent pattern group B composed of glass paste / platinum film / glass paste was formed on adjacent pattern group A using the second manufacturing method. Here, the pattern interval of the glass paste / platinum film was set to be about 1% of the pattern width of the glass paste. The formed adjacent pattern group B was pressed with a roller so that the printing pressure was 30 kPa. As a result, an adjacent pattern group B in which the gaps between the patterns were completely filled was obtained.

  Next, an adjacent pattern group C composed of glass paste / carbon film / glass paste was formed on the adjacent pattern group B using the second manufacturing method. Here, the pattern interval of the glass paste / carbon film was set to be about 1% of the pattern width of the glass paste. The formed adjacent pattern group C was pressed with a roller so that the printing pressure was 30 kPa. As a result, an adjacent pattern group C in which the gaps between the patterns were completely filled was obtained. Subsequently, the adjacent pattern group was fired using a firing furnace.

  The adjacent pattern group was formed as described above and immersed in a dye solution, and the dye was adsorbed on the porous semiconductor layer to obtain a photoelectric conversion layer. As the extraction electrode, a titanium plate provided with an electrolyte solution inlet was used. Thereafter, an electrolytic solution was injected from the electrolytic solution injection port of the extraction electrode using the capillary effect. Finally, a solar cell was completed by sealing the electrolyte injection port.

  In the dye-sensitized solar cell manufactured in this way, there was no gap between adjacent patterns that existed in the conventional printing method, and the adjacent pattern could be formed without gaps.

  In particular, in Example 2, the number of combinations of members to be controlled in the manufacturing apparatus 1A is smaller than that in Example 1, and the pattern position accuracy is more excellent. For this reason, when the gap between adjacent patterns is set to the same value as in the prior art, it is possible to reduce the printing pressure of the pressurizing means necessary to fill this gap. If the printing pressure is lowered, the decrease in film thickness at the time of pressurization is reduced, so that the film thickness design of the dye-sensitized solar cell becomes easy.

  Although the embodiments of the present invention have been described above, the embodiments and examples disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.

  According to the dye-sensitized solar cell, the method for manufacturing the dye-sensitized solar cell, and the apparatus for manufacturing the dye-sensitized solar cell according to the present invention, the adjacent patterns are formed on the substrate at regular intervals and then adjacent to each other. A pattern pressing process on the substrate is performed to press the substrate in the vertical direction so as to include all or part of the pattern. For this reason, since the adjacent pattern is extended in the horizontal direction of the substrate and the pattern gap is completely filled, the adjacent pattern is formed without a gap.

  As described above, the adjacent pattern does not contact at the stage of transfer onto the substrate, but contacts for the first time in the pattern pressing process on the substrate. At the time of pressing, since the ink is dried to such an extent that no material is mixed, there is no material diffusion / mixing at the bonding interface.

  By drying and firing the adjacent patterns formed in this way, the adjacent patterns can be formed on the substrate without gaps and with a short tact time (high tact time).
