  Hereinafter, embodiments of the present invention will be described in detail. For convenience of explanation, members having the same functions as those shown in the embodiments are denoted by the same reference numerals, and description thereof is omitted as appropriate.

Embodiment 1
An embodiment of the present invention will be described below with reference to FIGS.

<Outline of electronic device system>
FIG. 1 is a perspective view illustrating an outline of an electronic device system according to the present embodiment. As shown in FIG. 1, an electronic device system 100 according to this embodiment includes an electronic device 101, an electronic device cover (mounting member) 1, and a solar cell 2. 1A shows an outline of the electronic device 101 and the electronic device cover 1, and FIG. 1B shows an outline of the solar cell 2.

  The electronic device 101 is a portable information processing device such as an electronic book reader, a smartphone, or an electronic notebook, but is not limited to this. The electronic device cover 1 is attached to the electronic device 101 to cover the electronic device 101 and protect the electronic device 101 from impact or the like. The solar cell 2 converts light energy into electric energy. In the present embodiment, the electronic device 101, the electronic device cover 1, and the solar cell 2 are flat rectangular members. The electronic device 101 and the electronic device cover 1 have the same dimensions, and the solar cell 2 has a smaller size than the electronic device 101 and the electronic device cover 1.

  As shown in FIG. 1A, the electronic device cover 1 according to the present embodiment includes an accommodating portion 30 that accommodates the solar cell 2 in a state where power can be supplied from the solar cell 2 to the electronic device 101. The accommodating part 30 has an opening 13 for taking in and out the solar cell 2.

  According to said structure, it will be in the state which can supply electric power from the solar cell 2 to the electronic device 101 by making the solar cell 2 approach from the exterior via the opening part 13, and accommodating in the accommodating part 30. FIG. Since the solar cell 2 is accommodated in the accommodating portion 30 of the electronic device cover 1 attached to the electronic device 101, the solar cell 2 by external force is compared with the conventional technique in which the solar cell is attached to the surface of the mobile phone holder. Can be prevented from being damaged. Moreover, since the solar cell 2 accommodated in the accommodating part 30 can be taken out outside through the opening part 13, the solar cell 2 accommodated in the cover 1 for electronic devices can be replaced | exchanged easily.

<Details of solar cells>
In the present embodiment, a dye-sensitized solar cell (hereinafter abbreviated as “DSSC”) is used as the solar cell 2. The DSSC can generate power efficiently even with indoor lighting such as a fluorescent lamp, scattered light at a window, and other weak light, and is suitable for use in the portable electronic device 101.

The structure and power generation principle of the DSSC are as follows. That is, the DSSC includes titanium oxide on which a dye is adsorbed and an iodine-based electrolyte. In the dye that has absorbed light, electrons are excited, and the excited electrons are immediately injected into the conduction band of the titanium oxide and carried to an external circuit through one electrode (anode). The dye that has passed the electrons receives the electrons from the iodine ions I ⁻ of the iodine electrolyte and returns to the ground state. On the other hand, iodine ions that have passed the electrons become I ₃ ⁻ , and receive electrons from the external circuit via the other electrode (cathode). Thereby, a current flows through the external circuit.

  A transparent conductive film that transmits light is used for the anode, but the sheet resistance of the transparent conductive film is remarkably large. For this reason, when the DSSC is increased in size, the internal resistance increases and the performance of the solar cell deteriorates. In order to avoid this problem, most of the above DSSCs are modules having a structure in which elongated unit cells are arranged and adjacent unit cells are connected in series.

  The DSSC of this embodiment is a monolithic module. The monolithic module uses only one anode-side transparent substrate as a substrate, the cathode of unit cells arranged on the transparent substrate, and connection wiring between adjacent unit cells are formed by carbon paste or the like, The unit cells and connection wiring thus formed are sealed with a sealing material and further covered with a cover glass.

  Therefore, the solar cell 2 of this embodiment is a structure provided with the transparent substrate 21 and the cover glass 22, as shown to (b) of FIG. The transparent substrate 21 has a rectangular shape, and light is incident on the surface 210, and the incident light passes through the transparent substrate 21 and reaches the unit cell (not shown) to generate electric power.

  On the back surface 211 of the transparent substrate 21, the central portion is covered with the cover glass 22 and both side portions are exposed. On both sides, output terminals 212 are provided for outputting power from the arranged unit cells to the outside.

<Details of electronic device cover>
As shown to (a) of FIG. 1, in the cover 1 for electronic devices of this embodiment, it is dented from the center part of the cover main body 10 to the one end part of a longitudinal direction so that the downward direction may open, This recessed part Is the above-described accommodating portion 30. The accommodating portion 30 has an opening 13 for taking in and out the solar cell 2 and a holding portion 31 for holding the solar cell 2. One end of the cover main body 10 becomes the opening 13, and the central part becomes the holding part 31. Therefore, in the present embodiment, the longitudinal direction of the electronic device cover 1 is the direction in which the solar cell 2 is inserted and removed.

  According to said structure, since the solar cell 2 is hold | maintained by the holding | maintenance part 31, damage to the solar cell 2 by the external force being applied to the cover 1 for electronic devices and the solar cell 2 moving inside the accommodating part 30 is carried out. Can be prevented.

  The cover body 10 is preferably made of plastic. In addition, at least the upper surface of the holding unit 31 needs to be transparent so that light from the outside enters the solar cell 2 held by the holding unit 31.

  In the present embodiment, the first cross-sectional area when the space of the opening 13 is cut by the plane perpendicular to the longitudinal direction is greater than the maximum value of the second cross-sectional area when the space of the holding portion 31 is cut by the plane. Is also getting wider. Specifically, the holding unit 31 has a substantially constant height (length in the vertical direction), which is higher than that of the solar cell 2. In addition, the holding portion 31 has a substantially constant width (length in the short direction) and is the same or slightly wider than the solar cell 2. On the other hand, the opening portion 13 has the same height and a wider width than the holding portion 31.

  Therefore, since the opening 13 is wider than the end face of the solar cell 2, the solar cell 2 can easily enter the opening 13. Further, when the solar cell 2 enters the opening portion 13, the possibility that the corner portion of the solar cell 2 collides with the edge portion of the opening portion 13 is reduced, and as a result, damage to the solar cell 2 due to the collision is prevented. be able to. Moreover, even if a load more than necessary is applied to the solar cell 2 when the solar cell 2 is caught in the opening 13, the load can be dispersed because the solar cell 2 has a high degree of freedom. Damage to the battery 2 can be prevented.

  Further, in the present embodiment, the first cross-sectional area of the opening 13 becomes narrower as the holding unit 31 is approached. Thereby, the solar cell 2 can smoothly enter the holding unit 31 through the opening 13.

  FIG. 2 is a perspective view showing an outline of the electronic device cover 1. As shown in FIG. 2, the holding unit 31 includes a disc spring (elastic body) 11, a pressing plate 12, and a guide (guide unit) 14.

  The pressing plate 12 is an elongated plate-like member having flexibility, and is provided on both sides of the holding portion 31. The pressing plate 12 can be made of any flexible material such as metal, plastic, rubber, etc., but reduces the frictional resistance when the solar cell 2 enters and applies a uniform force to the solar cell 2. In order to apply, it is desirable that it is made of metal.

  One end of the disc spring 11 is attached to a plurality of appropriate locations (six locations in the example of FIG. 2) on the upper surface of the holding portion 31, and the other end is attached to a proper location on the pressing plate 12. Thereby, the pressing plate 12 is suspended (supported) from the upper surface of the holding portion 31 via the disc spring 11.

  Instead of the disc spring 11, an arbitrary elastic body such as a plate spring, a coil spring, or rubber may be used. However, for the reason described later, it is desirable that the pressing plate 12 moves only in the direction in which the solar cell 2 is pressed (vertical direction). Accordingly, a disc spring and a leaf spring are desirable as the elastic body used for the pressing plate 12.

  The guide 14 guides the solar cell 2 into the holding unit 31. The solar cell 2 can be smoothly advanced into the holding portion 31 by the guide 14. At this time, the pressing plate 12 contacts the solar cell 2 and moves upward. Thereby, the contact stress of the corner | angular part of the solar cell 2, and the press board 12 and the guide 14 is relieve | moderated, and the damage of the solar cell 2 can be prevented.

  Further, the guide 14 is arranged corresponding to the shape of the solar cell 2. In the present embodiment, since the solar cell 2 has spaces on both sides, the guide 14 is formed in an elongated prismatic shape and is disposed on both sides of the holding portion 31 so as to fit the space. The The guide 14 may be made of the same plastic as the cover body 10, but is made of metal that constitutes part of the wiring between the solar cell 2 and the electronic device 101 and is not easily deformed by the pressing plate 12. It is more preferable.

<Solar cell insertion process>
FIGS. 3A to 3D are cross-sectional views taken along the line AA in FIG. 2 and show a step of inserting (entering) the solar cell 2 into the electronic device cover 1.

  As shown in FIG. 2 and FIG. 3A, in this embodiment, the pressing plate 12 has a longer length (length in the longitudinal direction) and a shorter width than the guide 14. Further, the pressing plate 12 has a tip portion extending to the opening 13 and bent upward. In addition, the guide 14 is a collector for electrically connecting the output terminal 212 to the region in contact with the output terminal 212 of the solar cell 2, that is, the upper surface region, and supplying power from the solar cell 2 to the electronic device 101. An electric layer (current collecting member) 15 is provided.

  FIG. 3A shows a state in which the solar cell 2 is inserted into the opening 13. In the above state, since the disc spring 11 is not loaded, the pressing plate 12 exists at the lowest position.

  FIG. 3B shows a state in which the solar cell 2 is inserted up to the boundary between the opening 13 and the holding unit 31. In this state, the pressing plate 12 is moved upward with the tip portion in contact with the solar cell 2. As a result, the disc spring 11 is compressed, so that an urging force is applied from the pressing plate 12 to the solar cell 2 by the restoring force of the disc spring 11, and the solar cell 2 is caused by the frictional force between the solar cell 2 and the pressing plate 12. It is held by the holding unit 31. As a result, it is possible to prevent the solar cell 2 from falling off the holding part 31. Moreover, since it can prevent that the solar cell 2 collides at the boundary of the opening part 13 and the holding | maintenance part 31 by the press plate 12, damage to the solar cell 2 can be prevented.

  FIG. 3C shows a state in which the solar cell 2 is inserted up to the central portion of the holding unit 31. As the solar cell 2 is inserted into the holding portion 31, the area of the pressing plate 12 that moves upward by the solar cell 2 increases, so that the restoring force of the disc spring 11 increases and is applied to the solar cell 2 from the pressing plate 12. Increased urging power. Thereby, the solar cell 2 is firmly held by the holding unit 31.

  FIG. 3D shows a state in which the solar cell 2 is completely inserted into the holding unit 31. At this time, since the pressing plate 12 can press the whole of the both sides on the upper surface of the solar cell 2, the solar cell 2 is more firmly held by the holding portion 31.

  Furthermore, since the output terminal 212 of the solar cell 2 and the current collecting layer 15 of the guide 14 are in contact, power can be supplied from the solar cell 2 to the electronic device 101. Moreover, since the output terminal 212 of the solar cell 2 presses the current collecting layer 15 of the guide 14 by the pressing plate 12, the contact resistance between the output terminal 212 and the current collecting layer 15 can be reduced.

  In addition, when using said DSSC as the solar cell 2, it is preferable that the thickness of the transparent substrate 21 is 1 mm-4 mm. When the thickness of the transparent substrate 21 is less than 1 mm, the transparent substrate 21 and the pressing plate 12 are in point contact, particularly in the initial stage of insertion (see FIG. 3B), and the force applied to the contact point The solar cell 2 may be damaged. On the other hand, when the thickness of the transparent substrate 21 exceeds 4 mm, the dimensional accuracy of the thickness of the transparent substrate 21 is remarkably deteriorated, and the tip of the pressing plate 12 is caught by the transparent substrate 21 at the time of the insertion, and the pressing plate 12 is damaged. May occur.

  In the DSSC, the transparent substrate 21 is usually cut out from one transparent plate member. For this reason, a microcrack is generated on the cut surface of the transparent substrate 21. When a force is applied to the microcrack during the insertion, the transparent substrate 21 is easily damaged. Therefore, it is desirable that the region of the cut surface of the transparent substrate 21 that is in contact with the pressing plate 12 (that is, the upper surface edge of the transparent substrate 21) is chamfered.

Another embodiment of the present invention will be described below with reference to FIG.

  FIG. 4 is a perspective view showing an outline of the electronic device system according to the present embodiment. 4A shows an overview of the electronic device 101 and the electronic device cover 1a in the electronic device system 100a, and FIG. 4B shows an overview of the solar cell 2a in the electronic device system 100a. Show.

  The electronic device system 100a of the present embodiment is different from the electronic device system 100 shown in FIGS. 1 to 3 in the solar cell and the housing for the electronic device cover, and the other configurations are the same.

  The solar cell 2 shown in FIG. 1B has a structure in which elongated unit cells extending in the longitudinal direction are arranged in the lateral direction and adjacent unit cells are connected in series. For this reason, output terminals 212 are provided on both sides of the back surface 211 of the transparent substrate 21.

  On the other hand, the solar cell 2a of the present embodiment has a structure in which elongated unit cells extending in the lateral direction are arranged in the longitudinal direction and adjacent unit cells are connected in series. For this reason, as shown in FIG. 4B, output terminals 212a are provided at both ends of the back surface 211a of the transparent substrate 21a.

  Moreover, the accommodating part 30a in the cover 1a for electronic devices of this embodiment is provided from the center part of the cover main body 10a to the one end part of a transversal direction. In this case, the opening part 13a in the accommodating part 30a is provided in the one end part of the transversal direction of the cover main body 10a. Further, the disc spring 11a, the pressing plate 12a, and the guide 14a included in the holding portion 31a in the accommodating portion 30a are provided along the short direction.

  Thus, in this invention, the solar cell 2 can be made to approach from the arbitrary directions of the cover 1 for electronic devices by providing the accommodating part 30 according to the approach direction (entrance / exit direction) of the solar cell 2. FIG.

[Embodiment 3]
The following will describe still another embodiment of the present invention with reference to FIG.

  FIG. 5 is a perspective view showing an outline of the electronic device system according to the present embodiment. 5A shows an outline of the electronic device 101 and the electronic device cover 1b in the electronic device system 100b, and FIG. 5B shows an outline of the solar cell 2b in the electronic device system 100b. Show. The electronic device system 100b according to the present embodiment is different from the electronic device system 100 shown in FIGS. 1 to 3 in the solar battery and the cover for the electronic device cover, and the other configurations are the same.

  The solar cell 2b of this embodiment is a Z-type module DSSC. In the Z-type module, a plurality of unit cells are connected in series via an interconnect between an anode-side transparent substrate 21 and a cathode-side substrate. Therefore, the solar cell 2b of the present embodiment is configured to include the transparent substrate 21 and the cathode side substrate 23, as shown in FIG. The cathode side substrate 23 may be a transparent glass substrate or a plastic substrate, or may be an opaque printed substrate.

  The transparent substrate 21 and the cathode side substrate 23 are arranged so as to be shifted in the lateral direction. An anode-side output terminal 213 is provided on the exposed portion of the back surface 211 of the transparent substrate 21, while a cathode-side output terminal 233 is provided on the exposed portion of the back surface 231 of the cathode-side substrate 23.

  Incidentally, the solar cell 2b shown in FIG. 5 (b) has the same shape of the side portion on the one side (left side with respect to the entering direction) as compared with the solar cell 2 shown in FIG. The shape of the side part on the right side with respect to the approach direction is different.

  Therefore, the disc spring 11, the pressing plate 12, and the guide 14 are provided on the left side in the approach direction of the holding portion 31b of the electronic device cover 1b of the present embodiment, similarly to the holding portion 31 shown in FIG. . On the other hand, unlike the holding portion 31 shown in FIG. 2, a leaf spring 11b, a pressing plate 12b, and a guide 14b are provided on the right side of the holding portion 31b in the approach direction. Specifically, a leaf spring 11b and a pressing plate 12b are provided on the substantially right half of the lower portion of the holding portion 31b. A guide 14b is provided on the upper right side of the holding portion 31b.

  The pressing plate 12b is supported upward by the leaf spring 11b. A current collecting layer 15b is provided on the lower surface of the guide 14b.

  In the upper part of the holding part 31b, it is necessary not to block light incident on the solar cell 2b, but in the lower part of the holding part 31b, this is not necessary. Accordingly, the pressing plate 12b provided at the lower portion of the holding portion 31b can be wider than the pressing plate 12 provided at the upper portion of the holding portion 31b. As a result, the holding unit 31b can hold the solar cell 2b more firmly. Moreover, since the contact area of the solar cell 2b and the press plate 12b becomes large, insertion of the solar cell 2b can be performed smoothly. In addition, it is desirable that the width of the guide 14b provided on the upper portion of the holding portion 31b is narrower than that of the guide 14 provided on the lower portion of the holding portion 31b.

  By the way, the solar cell 2b of this embodiment is a DSSC of a Z-type module as described above. In the Z-type module DSSC, a sealing material is provided on both sides of each unit cell. This sealing material is for isolating the electrolyte contained in the unit cell for each unit cell, or for electrically insulating the interconnect provided between the unit cells and the unit cell. is there. The sealing material is made of a resin having mechanical strength such as an acrylic resin or an epoxy resin. Therefore, even if the solar cell 2 is more firmly held by the holding portion 31 by the pressing plate 12b, the sealing material suppresses the deformation of the cathode side substrate 23, and as a result, the solar cell 2 is prevented from being damaged. Can do.

The following will describe still another embodiment of the present invention with reference to FIG.

  FIG. 6 is a perspective view showing an outline of the electronic device system according to the present embodiment. 6A shows an overview of the electronic device 101 and the electronic device cover 1c in the electronic device system 100c, and FIG. 6B shows an overview of the solar cell 2c in the electronic device system 100c. Show. The electronic device system 100c of the present embodiment is different from the electronic device system 100 shown in FIGS. 1 to 3 in the solar battery and the cover for the electronic device cover, and the other configurations are the same.

  The solar cell 2c of this embodiment is a plate-like Si solar cell. Output terminals 213c and 233c on the anode side and the cathode side are provided on both sides of the back surface of the solar cell 2c.

  The holding unit 31c of the electronic device cover 1c of the present embodiment is different from the holding unit 31 shown in FIG. 2 in that a guide 14c is provided instead of the guides 14 and 14, and the other configurations are the same. It is.

  The guide 14c is provided on the entire lower portion of the holding portion 31c. The guide 14c is provided with a current collecting layer (not shown) in a region in contact with the output terminals 213c and 233c of the solar cell 2c, that is, on both sides of the upper surface.

  Thus, this invention can accommodate the solar cell 2 of arbitrary shapes by changing the shape and arrangement | positioning of the press plate 12 and the guide 14 in the holding | maintenance part 31. FIG.

[Embodiment 5]
The following will describe still another embodiment of the present invention with reference to FIG.

  FIG. 7 is a plan view showing an outline of the electronic device cover 1d in the electronic device system according to the present embodiment. The electronic device system 100d of the present embodiment is different from the electronic device system 100 shown in FIGS. 1 to 3 in the pressing plate in the holding unit of the electronic device cover, and the other configurations are the same.

  (A)-(c) of FIG. 7 has shown the example of the press plate 12 in the holding part 31d of the cover 1d for electronic devices. In the example of FIG. 7A, the tip portions (end portions on the opening 13 side) of the two pressing plates 12 and 12 are connected by a connecting plate 17. The function of regulating the movement of the pressing plate 12 is improved by the connecting plate 17. Accordingly, when the pressing plate 12 moves unexpectedly, the durability of the pressing plate 12 decreases, or the pressing plate 12 shields a part of the light receiving surface of the solar cell 2 and the performance of the solar cell 2 decreases. Can be prevented.

  Further, in the example of FIG. 7B, the base end portions of the two pressing plates 12 and 12 are further connected by the connecting plate 17 as compared with the example of FIG. Thereby, since the movement of the pressing plate 12 is further restricted, it is possible to further prevent the durability of the pressing plate 12 from being lowered and the performance of the solar cell 2 from being lowered.

  In addition, in the example of FIG. 7C, compared to the example of FIG. 7B, the inside of the opening 13 is formed from the tip portions of the two pressing plates 12 and 12 and the connecting plate 17 that connects the tip portions. An extension plate 18 further extending to the center is further provided. The extending plate 18 is aligned in the short direction. Thereby, when the solar cell 2 enters, one side of the solar cell 2 comes into contact with the distal end portion of the extending plate 18, so that the solar cell 2 can enter more smoothly. Moreover, since the stress at the time of the contact can be further relaxed, damage to the solar cell 2 and the pressing plate 12 can be further prevented.

  Note that the pressing plate 12, the connecting plate 17, and the extending plate 18 are preferably formed integrally. Further, the connecting plate 17 and the extending plate 18 are preferably suspended by the disc spring 11 similarly to the pressing plate 12.

The following will describe still another embodiment of the present invention.

  The electronic device system of the present embodiment is different in the elastic coefficient of the disc spring 11 from the electronic device system shown in FIGS.

  In the present embodiment, the disc spring 11 on the opening 13 side has a lower elastic coefficient than the other disc springs 11, and the elastic coefficient of the disc spring 11 increases as it advances in the entry direction. Thereby, when making the solar cell 2 approach into the holding | maintenance part 31 from the opening part 13, the force which pushes in the solar cell 2 may be small, and as a result, the approach of the solar cell 2 can be performed further smoothly. Further, when the solar cell 2 is completely entered into the holding portion 31, the solar cell 2 b can be firmly held by the other disc spring 11.

[Embodiment 7]
The following will describe still another embodiment of the present invention.

  The electronic device system of the present embodiment is different from the electronic device system shown in FIGS. 1 to 3 in that the guide 14 includes a belt conveyor, and other configurations are the same. Thereby, since the belt conveyor of the guide 14 will operate | move when the solar cell 2 is entered into the holding | maintenance part 31, it can enter more smoothly. Instead of the belt conveyor, a roller conveyor or other transport device may be used.

[Embodiment 8]
The following will describe still another embodiment of the present invention with reference to FIG.

  FIG. 8 is a perspective view showing an outline of an electronic device cover in the electronic device system according to the present embodiment. Compared to the electronic device system 100 shown in FIGS. 1 to 3, the electronic device system 100 e of this embodiment is a plate spring (pressing plate) instead of the disc spring 11 and the pressing plate 12 in the holding portion 31 of the electronic device cover 1. (Plate, elastic body) 19 is provided, and other configurations are the same. In this case, since the number of parts is reduced, it is easy to manufacture the electronic device cover 1e.
