Hereinafter, embodiments of the series-connected and parallel-connected solar cells of the present invention will be described with reference to the drawings.

First, using FIGS. 1 to 4, the formation of the solar cell series connection circuit and the installation of the solar cell are extremely easy, simple and reliable to describe the solar cell installation structure X1 of the present invention.

As shown in Figure 1, the solar cell installation structure X1 has panel-type solar cells 1a-1c and an installation tool 2. The installation tool 2 can form a series connection circuit and install the solar cells 1a-1c in a building not shown. Installation objects such as walls or roofs.

As an example, as shown in Fig. 2 where 1a shown in Fig. 1 is observed on the P1-P1 line, any solar cell can be used as the solar cell 1a as long as it has a flat photoelectrode 3 and an antipole 4 -1c. In this embodiment, the dye-sensitized solar cell (hereinafter simply referred to as "battery") 1a-1c shown in FIG. 1 is illustrated, and the solar cell mounting structure X1 will be described. In addition, in FIG. 3, the photoelectrode 3 and the counter electrode 4 are shown slightly shifted in the short-side direction for easy understanding of the structure (the same applies to FIGS. 5 and 6 described later).

As the batteries 1a-1c, well-known batteries can be used. As shown in FIG. 2, the battery 1a is filled with an electrolyte (not shown) in the internal space K, and the photoelectrode 3 and the counter electrode 4 are bonded along the outer edge G to form a substantially rectangular shape in plan view (see figure 1). Furthermore, the batteries 1b and 1c have the same structure as the battery 1a.

Also, an electrolyte layer may be used instead of the electrolyte. The aforementioned electrolyte layer has the same function as the electrolyte solution, and is in either a gel state or a solid state. The following electrolyte layer can be used as the aforementioned electrolyte layer. The electrolyte layer is an electrolyte layer obtained by adding a gelling agent or a thickening agent to the electrolyte, and removing the solvent as required, thereby gelling or solidifying the electrolyte . By using a gel or solid electrolyte layer, there is no risk of electrolyte leakage from the batteries 1a-1c.

The photoelectrode 3 forms a transparent conductive film 6 on the surface 5a of the transparent substrate 5, thereby forming a porous semiconductor 7 so that the semiconductor 7 carries the dye. The counter electrode 4 is formed by forming a conductive film 9 on the surface 8 a of the substrate 8.

The end (the end on one side) 10 extending in the short-side direction (the direction toward the depth of the paper in FIG. 2) along the side 3a of the photoelectrode 3 protrudes from the end 4a of the counter electrode 4, and the transparent conductive film 6 is exposed And constitute the first electrode terminal 21.

As shown in FIG. 3, the first electrode terminal 21 is formed with a notch 18 formed by cutting the middle portion in the short-side direction into a rectangle. The notch 18 is formed at a position deviated from the center of the photoelectrode 3 in the short-side direction in the short-side direction.

As shown in FIG. 2, the end portion (the end portion on the opposite side) of the counter pole 4 extending in the short-side direction along the opposite side 3b protrudes from the end edge 3d of the photoelectrode 3, and the conductive film 9 is exposed to constitute the first 2 electrode terminal 22.

As shown in FIG. 3, the 2nd electrode terminal 22 is formed with the notch 19 which cut|disconnected both ends in a short direction into a rectangle.

The first electrode terminal 21 and the second electrode terminal 22 are formed so as to protrude in opposite directions (that is, a direction orthogonal to the arrangement direction of the batteries 1a-1c) and face opposite surfaces.

The mounting tool 2 includes a pair of holding members 15A, 15B, and the pair of holding members 15A, 15B is shown in FIG. 1 so that the first electrode terminal 21 and the second electrode terminal 22 form side ends In the method of the parts S1 and S2, a plurality of batteries 1a-1c are arranged in one direction, and the side end parts S1, S2 are gripped from a direction orthogonal to the one direction. "Side end portions S1, S2" refer to the side end portions of the batteries 1a, 1b, and 1c arranged in an overall shape. The batteries 1a, 1b, and 1c are connected in a straight line with the first electrode terminal 21 and the second electrode terminal 22 to form a pair of side ends S1, S2. The first electrode terminal 21 of each battery 1a-1c and The direction between the second electrode terminals 22 faces a direction orthogonal to the arrangement direction of the batteries 1a-1c.

As shown in FIG. 3, the gripping members 15A each have: a fixing portion 16A that arranges the first electrode terminal 21 and the second electrode terminal 22 on a straight line alternately and side by side; and a pressing portion 17A that faces the fixing portion 16A The first electrode terminal 21 and the aforementioned second electrode terminal 22 are arranged facing the ground.

The gripping members 15B each have: a fixing portion 16B that arranges the first electrode terminal 21 and the second electrode terminal 22 on a straight line alternately and side by side; and a pressing portion 17B that is arranged opposite to the fixing portion 16B and sandwiched The first electrode terminal 21 and the aforementioned second electrode terminal 22.

The fixing portion 16A is formed into a long rectangle using an insulating material such as a synthetic resin material.

On the surface 16s of the fixing portion 16A, a first fitting concave portion 25 and a second fitting concave portion 26 in which the ends 10 and 11 of the batteries 1a-1c are placed are formed.

The first fitting recessed portion 25 and the second fitting recessed portion 26 are alternately formed in the longitudinal direction of the fixed portion 16A so as to open on the side of one end 16a in the short direction of the fixed portion 16A.

In a plan view, the first fitting recess 25 is formed to be slightly larger than the end 10 in accordance with the outer shape of the end 10. Furthermore, a protrusion 25a is formed on the bottom surface 25t of the first fitting recess 25, and the protrusion 25a is fitted to the first electrode terminal 21 when the first electrode terminal 21 is arranged facing the first fitting recess 25 Gap 18. The notch 18 and the protrusion 25a are formed to correspond to each other at positions deviated from the center of the short side direction of the battery 1a.

In a plan view, the second fitting recess 26 is formed to be slightly larger than the end 11 in accordance with the outer shape of the end 11. Moreover, a protrusion 26a is formed on the bottom surface 26t of the second fitting recess 26. When the second electrode terminal 22 faces the same direction as the bottom surface 26t (that is, when facing the front of the paper in this figure, the protrusion 26a is When), fit in the gap 19.

The depths of the first fitting recess 25 and the second fitting recess 26 are formed to be smaller than the thickness dimension of the batteries 1a-1c.

In this way, the shapes of the first fitting recess 25 and the end 10 are not formed symmetrically with respect to the center line in the short-side direction, and the first fitting recess 25 and the second fitting recess 26, and the end 10 and the end Also, 11 is not formed symmetrically with respect to the center line in the longitudinal direction. Therefore, as shown in FIG. 3, when the end 10 is to be arranged so that the first electrode terminal 21 faces the bottom surface 25t, the end 10 is fitted in the first fitting recess 25. However, when the end 10 is to be arranged with the first electrode terminal 21 facing the opposite surface, the protrusion 25a does not mesh with the notch 18, so the protrusion 25a of the first fitting recess 25 prevents the end 10 from being fitted.

Also, even if it is desired to fit the end 10 into the second fitting recess 26, and to fit the end 11 into the first fitting recess 25, the projections 25a of the first fitting recess 25 and the second fitting recess 26 , 26a will also prevent the end 11 and the end 10 from fitting.

On the surface 16s of the fixed portion 16A on which the first fitting concave portion 25 and the second fitting concave portion 26 are formed, the first fitting concave portion 25 and the second fitting concave portion 26 are each set in one set, covering the first fitting The conductive material E is continuously arranged between the recessed portion 25 and the second fitting recessed portion 26.

Specifically, across the first electrode terminal 21 corresponding to the battery 1a and the battery 1b The conductive material E is continuously provided in the first fitting recess 25 and the second fitting recess 26 of the second electrode terminal 22. Moreover, on the side of the fixed portion 16A, the conductive material E is not provided between the battery 1b and the battery 1c, and the surface of the first fitting recess 25 corresponding to the first electrode terminal 21 of the battery 1c is provided on the battery 1c side. The terminal 45 at one end is further provided with a conductive material E.

In the longitudinal direction of the fixing portion 16A and the pressing portion 17A, as shown in FIG. 4, when the battery 1a-1c is sandwiched between the fixing portion 16A and the pressing portion 17A, the position penetrates the second electrode terminal 22 and the conductive material E A through hole 30 is formed. A fastening member 40 such as a screw can be inserted into the through hole 30.

In the fixed portion 16B, a second fitting concave portion 26, a first fitting concave portion 25, and a second fitting concave portion 26 are sequentially formed so that an electrode terminal opposite to the electrode terminal fitted in the fixed portion 16A can be provided. . In addition, in the fixing portion 16B, a conductive material E is provided so as to conduct conduction between the terminal 45 and the second fitting recess 26, and the terminal 45 is formed at an end portion corresponding to the battery 1a. Furthermore, the conductive material E is continuously formed across the first fitting recess 25 corresponding to the first electrode terminal 21 of the battery 1b and the second fitting recess 26 corresponding to the second electrode terminal 22 of the battery 1c.

In the longitudinal direction of the fixing portion 16B and the pressing portion 17B, as shown in FIG. 4, when the batteries 1a-1c are sandwiched between the fixing portion 16B and the pressing portion 17B, the position penetrates the second electrode terminal 22 and the conductive material E A through hole 30 is formed. A fastening member 40 such as a screw can be inserted into the through hole 30.

In this way, the conductive material E is provided in the fixed portion 16A and the fixed portion 16B so that the combination of the first fitting recess 25 and the second fitting recess 26 is shifted one by one. The conductive material E is formed in a long strip shape, and a first conductive portion 27 is formed in the fixed portion 16A, and a second conductive portion 28 is formed in the fixed portion 16B.

The conductive material E is composed of a specific thickness (for example, 10 μm or more and 500 μm The following left and right) conductive tape or conductive paste.

The pressing parts 17A and 17B are formed in the same outer shape as the fixing part 16A using insulating materials such as synthetic resin materials.

The fastening member 40 is formed to be slightly larger than the cross-sectional area of the through hole 30, and when inserted into the through hole 30, comes into contact with the second electrode terminal 22 and the first conductive portion 27 and the second electrode terminal 22 and the second conductive portion 28. In addition, as the fastening member 40, a member can be used that can fasten the fixing portion 16A (16B) and the pressing portion 17A (17B) in close contact and has conductivity.

In this way, the second electrode terminal 22 and the conductive material E are electrically connected by the fastening member 40. Furthermore, the notches 18, 19, the first fitting recess 25, and the second fitting recess 26 constitute an engaging portion or an engaged portion, and the engaging portion or the engaged portion can be electrically connected to the batteries 1a-1c only in the direction. When the direction of the sexual connection is allowed to fit (arrange), when the direction is other than this direction, it is not allowed to be arranged in a snapped manner.

Next, a method of mounting the batteries 1a-1c on the mounting tool 2 and a method of forming a series connection circuit by the mounting tool 2 will be described.

First, as shown in FIG. 3, the fixing portions 16A and 16B are arranged so that the batteries 1a-1c can be fitted into the space between the fixing portion 16A and the fixing portion 16B.

The first electrode terminals 21 of the batteries 1a and 1c are opposed to the bottom surface 25t, and the end portion 10 is fitted into the first fitting recess 25 of the fixing portion 16A. In this way, the second electrode terminal 22 is directed in the same direction as the bottom surface 26t, and the end portions 11 of the batteries 1a and 1c are fitted into the second fitting recesses 26 of the fixing portion 16B.

The second electrode terminal 22 of the battery 1b is directed in the same direction as the bottom surface 26t, and the end portion 11 is fitted into the second fitting recess 26 of the fixing portion 16A. In this way, the first electrode terminal 21 is opposed to the bottom surface 25t, and the end 10 of the battery 1b is fitted into the first fitting recess 25 of the fixing portion 16B.

Next, with the end portions 10 and 11 interposed therebetween, the pressing portion 17A is arranged on the surface 16s of the fixing portion 16A. Then, the fastening member 40 is inserted into the through hole 30 to fasten the fixing portion 16A and the pressing portion 17A.

Similarly, the pressing portion 17B is arranged on the surface 16s of the fixing portion 16B. Then, the fastening member 40 is inserted into the through hole 30 to fasten the fixing portion 16B and the pressing portion 17B.

In this way, the first electrode terminal 21 is in direct contact with the conductive material E, and the second electrode terminal 22 is in contact with the conductive material E through the fastening member 40. As a result, the terminal 45 of the holding member 15B, the second conductive portion 28, and the second electrode terminal 22 of the battery 1a are electrically connected. In addition, the adjacent batteries 1a-1b are electrically connected by the first conductive portion 27 in the holding member 15A. Furthermore, the batteries 1b-1c are electrically connected by the second conductive portion 28.

In this state, the installation tool 2 holding the batteries 1a-1c is attached to the installation target such as the wall or roof of the building by using adhesive tape or screws.

As described above, after the batteries 1a-1c are mounted on the pair of holding members 15A, 15B, from the terminal 45 of the holding member 15B to the battery 1a, from the battery 1a to the battery 1b, from the battery 1b to the battery 1c, and from the battery 1c to the holding The terminals 45 of the member 15A are connected in sequence to form a series connection circuit extremely simply.

In addition, the first conductive portion 27 and the second conductive portion 28 are formed in a long strip shape so as to contact the opposed first electrode terminal 21 over a large area. Furthermore, by firmly tightening the fastening member 40, the pressing parts 17A, 17B are fixed in a state where they are strongly in close contact with the fixing parts 16A, 16B. Therefore, the conductive material E in contact with the first electrode terminal 21 is made strong with the largest possible area The ground is in close contact with the first electrode terminal 21.

In this way, the solar cell mounting structure X1 produces the following effect: as long as the gripping member 15A and the gripping member 15B grip the ends 10, 11 of the batteries 1a-1c and fasten them with the fastening member 40, the solar cell can be easily attached 1a-1c are installed in the installation target. In addition, the solar cell mounting structure X1 has the following effect: a series connection circuit can be formed simply and surely.

In addition, the mounting structure X1 of the solar cells 1a-1c has notches 18, 19 formed on the cells 1a-1c, and protrusions 25a, 26a are formed on the fixing members 16A, 17A. Therefore, for the solar cell mounting structure X1, if there is a difference in the electrode direction and the front and back of the batteries 1a-1c, the end portions 10, 11 cannot be arranged in the fixed portions 16A, 16B. That is, the solar cell mounting structure X1 has the following effect: it can prevent the misconfiguration of the solar cells 1a-1c, thereby forming an appropriate and directly connected circuit.

In addition, the installation structure X1 of the solar cell produces the following effect: Since the structure of the installation tool 2 is extremely simple, the appearance is excellent.

Furthermore, in the above-exemplified embodiment, three dye-sensitized solar cells can be installed on the holding members 15A and 15B, but the installed number can be appropriately set.

Moreover, in the notches 18 and 19, as long as there is more than one notch that is not formed at a line-symmetrical position, several other notches may be formed at any position or in any shape. However, considering that two holding members 15A and 15B of the same shape can be used as a set, it is preferable to form the notches 18 and 19 rotationally symmetrically.

Furthermore, in the above-mentioned embodiment, examples of the engaging portion and the engaged portion have been described based on the notches 18 and 19, but the engaging portion and the engaged portion may also be formed by recesses and protrusions that fit each other, or phases. Corresponding through holes and insertion parts are formed.

Furthermore, in the above-mentioned embodiment, the configuration is as follows, that is, the photoelectrodes of all the batteries 1a-1c are facing the same surface and the batteries 1a-1c are mounted on the holding members 15A, 15B, but the direction of the batteries 1a-1c It is not limited to the directions explained above. That is, when the counter electrode 4 is formed in a light-transmitting manner, or when not all batteries are used for power generation, the following mounting structure can also be set: the counter electrode 4 of a part of the battery faces the same as the photoelectrode 3 Direction, and the battery is held by the holding members 15A, 15B.

Specifically, for example, it can be set as the mounting structure X2 of the solar cell as shown in FIG. That is, the photoelectrode 3 is directed to the front, and the battery 1a is gripped by the gripping members 15A and 15B. The battery with the same structure as the battery 1a is turned over so that the reverse electrode 4 faces the front, and the battery 1b is held by the holding members 15A and 15B in the posture after changing the direction of the electrode terminals. Furthermore, in the same posture as the battery 1a, the holding members 15A and 15B hold the battery 1c having the same structure as the battery 1a.

The conductive material E is continuously provided between the first fitting recess 25 and the second fitting recess 26 of the holding member 15A corresponding to the first electrode terminal 21 of the battery 1a and the second electrode terminal 22 of the battery 1b.

In addition, the conductive material E is continuously provided between the remaining first fitting recess 25 and the terminal 45 of the holding member 15A.

In the gripping member 15B, the terminal 45 is provided at the end of the pressing portion 17B, and the conductive material E is provided on the plate surface of the pressing portion 17B facing the second electrode terminal 22 of the battery 1a. Furthermore, the conductive material E is continuously provided on the plate surface of the pressing portion 17B facing the first electrode terminal 21 of the battery 1b and the second electrode terminal 22 of the battery 1c.

By providing the conductive material E on the holding members 15A and 15B in the above-mentioned manner, and allowing the holding members 15A and 15B to hold the batteries 1a-1c, the series connection can be easily and reliably realized. In addition, all the electrode terminals can face the conductive material E and directly contact the conductive material E. Therefore, it has the effect of more reliable electrical connection.

Furthermore, as shown in FIG. 5, one corner of the batteries 1a-1c may be cut into a triangle to form the notch 18, and the opposite corner of the notch 18 may be cut into a rectangle to form the notch 19. Even if the notches 18 and 19 are formed in the above-mentioned manner, it can effectively prevent the wrong arrangement of the front and back of the batteries 1a-1c and the direction.

Next, an embodiment of the solar cell mounting structure X3 of the present invention forming a parallel connection circuit will be described with reference to FIG. 6. In this embodiment, the same components as those of the solar cell mounting structure X1 of the series-connected circuit are given the same reference numerals, and the description thereof is omitted.

The first electrode terminals 21 of the solar cell mounting structure X3 of the present embodiment all face the same direction and the same surface side, and are electrically connected by the first conductive portion 27 of one holding member 15A. In addition, the second electrode terminals 22 also face the same direction and the same surface side in the same manner, and are electrically conducted by the second conductive portion 28 of the other holding member 15B.

According to the above configuration, the solar cell mounting structure X3 can form a parallel connection circuit extremely simply and reliably, and the batteries 1a-1c can be easily mounted to the mounting object. In addition, the same functions and effects as the foregoing embodiment can be produced.

Furthermore, the mounting structure of the solar cell of the present invention only needs to make the direction between the first electrode terminal 21 and the second electrode terminal 22 of each battery face a direction orthogonal to the arrangement direction, and arrange a plurality of batteries in one direction, which is appropriate A conductive material E is formed on the fixing parts 16A, 16B and the pressing parts 17A, 17B, and a plurality of batteries are clamped and held in a direction orthogonal to the arrangement direction (one direction) by the holding members 15A, 15B to realize electrical connection , It can also be of any configuration.
