2. Description of the Related Art A photoelectric conversion element, which is also called a solar cell, is an element for converting light energy such as sunlight into electric energy. Unlike the fossil fuels that have been conventionally used, this photoelectric conversion element does not emit carbon dioxide or the like when extracting electric energy from light energy. In addition, since the photoelectric conversion element can extract electric energy from light energy such as sunlight, which is said to be almost inexhaustible, it can generate power semipermanently. Therefore, in consideration of global environmental problems, it is considered that the usage and scale of use of the photoelectric conversion element will continue to expand in the future (for example, JP 2001-2369 A).
99 gazette, JP 2001-230435 A, JP 2001-231001 A, etc.). However, the photoelectric conversion element requires a large light receiving area in order to obtain a predetermined amount of electric power suitable for use, because the light energy such as sunlight exists in a spatially diluted state.

On the other hand, due to the progress of various processing techniques in recent years,
The miniaturization of electric or electronic devices is progressing, and electric or electronic devices are often regarded as portable devices. For this reason, dry batteries, which are convenient and easy to carry, are usually used as a power source for electric or electronic devices. Therefore, it is considered that dry batteries will be used more and more in the future.

However, the dry battery is usually a primary battery such as a manganese dry battery or an alkali manganese dry battery, and is discarded by one discharge, which is preferable from the viewpoints of economical, resource and environmental load. Not a thing. In addition, a NiMH-based secondary battery having the same standard shape as a dry battery is also used, but in view of the low charging efficiency,
It cannot be said that the electric power is generated by the means for giving a load to the global environment, like the primary battery (for example, JP-A-7-326371 and JP-A-8-0078).
99 gazette, JP 2001-217000 A, JP 2000-30699 A, etc.).

However, the conventional photoelectric conversion element lacks flexibility, and a photoelectric conversion element for the irradiation area of light necessary for obtaining a sufficient amount of electric power is required. , Poor portability. On the other hand, it is outdoors that photoelectric conversion elements can obtain sufficient power.
The electric or electronic device that can be used outdoors is a highly portable electric or electronic device. Therefore, the photoelectric conversion element is required to have good portability. Therefore, the present invention uses a photoelectric conversion element having flexibility,
With the aim of making it possible to use light energy such as sunlight as a power source for commonly used electric or electronic devices, and replacing it with a standard battery, a photovoltaic device that serves as a power source for general-purpose electric or electronic devices, An object is to provide an accessory for a photovoltaic device using the same, and an electric or electronic device using the accessory.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, in the drawing, regarding the photoelectric conversion sheet 3, a start point and an end point are illustrated, and an intermediate part thereof is omitted. Below,
First, the photovoltaic device 1 shown in FIG. 1 will be described. However, it goes without saying that the present invention is not limited to these.

The photovoltaic device 1 according to the present invention comprises a winding core 2
And a photoelectric conversion sheet 3 provided with a flexible photoelectric conversion element 31 wound around the winding core portion 2 so as to be drawn out, and the photoelectric conversion sheet 3 on the winding core portion 2. In the wound state, it is configured to have a substantially cylindrical shape as a whole.

The winding core 2 is formed of a resin material in a cylindrical shape. Examples of the resin material include ABS
(Acrylonitrile-butadiene-styrene) resin, S
AN (styrene-acrylamide) resin, ASA (acrylonitrile-styrene-acrylamide) resin, AC
It is preferable to use S (acrylonitrile-chlorinated polyethylene-styrene) resin or AAS (acrylonitrile-acrylate-styrene) resin. The winding core portion 2 is formed to be slightly longer than the width of the photoelectric conversion sheet 3 in a state where the photoelectric conversion sheet 3 is wound. Therefore, the winding core portion 2 can be wound around the entire width of the photoelectric conversion sheet 3, and the photoelectric conversion sheet 3 does not protrude. Further, the winding core portion 2 is provided with an upper flange 6 and a lower flange 7 at both ends thereof.

The upper flange 6 and the lower flange 7 are
The resin material is formed into a substantially circular flat plate shape, and is fixed to both ends of the winding core portion 2 by a fixing means such as an adhesive. Examples of the resin material include the resins exemplified as the above resin material, and the resin material may be formed of the same material as the winding core portion 2 or may be formed of a different material. The upper flange 6 and the lower flange 7 are formed so that their diameters are substantially the same as the diameter of the photoelectric conversion sheet 3 wound around the winding core 2. Thereby, the upper flange 6 and the lower flange 7 can protect the side edge portions of the photoelectric conversion sheet 3 wound around the winding core portion 2, and the extracted photoelectric conversion sheet 3 can be wound around the winding core portion 2.
It serves as a guide for winding onto the core, and the photoelectric conversion sheet 3 can be wound around the winding core 2 without displacement.

The winding core portion 2, the upper flange 6 and the lower flange 7 are preferably made of a material having an electric insulation property. Examples of the material exhibiting electrical insulation include liquid crystal polymers, engineered plastics such as modified polyphenylene ether (PPE), polyetheretherketone (PEEK), and polyphenylene sulfide, which are chemically resistant, heat resistant, and creep resistant. (P
PS), polyether sulfone (PES), polysulfone (PSF) and the like. As a result, in the photovoltaic device 1 according to the present invention, when the internal wiring is short-circuited via these respective parts or is used for discharge, these respective parts come into contact with, for example, the terminals of the battery housing part of the electric or electronic device. As a result, it is possible to prevent an electrical short circuit.

It is desirable that the winding core 2, the upper flange 6 and the lower flange 7 are made of a material having excellent heat insulating properties. Examples of the material having excellent heat insulation properties include polyamide resins such as para-aramid resin and meta-aramid resin, vinyl chloride resin, polyester resin, polyethylene resin, polystyrene resin or polyurethane resin. . This prevents the photovoltaic device 1 from being deformed or damaged due to an increase in temperature of the photovoltaic device 1 when exposed to a high temperature such as being left on a dashboard of an automobile. . Furthermore, it is desirable that the winding core 2, the upper flange 6, and the lower flange 7 be colored in a color such as white that is hard to absorb light and heat. As a result, the photovoltaic device 1 can be prevented from being damaged due to an increase in temperature.

On the upper flange 6 and the lower flange 7,
A positive electrode terminal 8 and a negative electrode terminal 9 are provided respectively.
The positive electrode terminal 8 and the negative electrode terminal 9 are made of a conductive material, and are electrically connected to predetermined positions by connecting means (not shown). Examples of the conductive material include a metal such as aluminum, iron or nickel,
Examples thereof include metal alloys such as iron-nickel alloys, copper-nickel alloys, platinum-rhodium alloys, and gold-silver alloys.

The photoelectric conversion sheet 3 is composed of a sheet-shaped substrate having flexibility and formed in a substantially rectangular sheet shape, and a plurality of photoelectric conversion elements 31 arranged on the sheet-shaped substrate. . The sheet-shaped substrate is formed of an insulating material such as polyester, and is formed in a sheet shape so as to have flexibility. Each photoelectric conversion element 31 is formed by sequentially stacking a first electrode layer, a photoelectric conversion layer, and a second electrode layer in a thin film shape on a sheet-shaped substrate. Each layer constituting the photoelectric conversion element 31 is, for example, various PV typified by a sputtering method or a vapor deposition method.
The thin film is formed on the sheet-shaped substrate by the D method or various CVD methods represented by the plasma CVD method and the MOCVD method. Since each layer of the photoelectric conversion element 31 is formed in a thin film shape, the photoelectric conversion element 31 has sufficient flexibility like a sheet substrate.

In the photoelectric conversion sheet 3, the photoelectric conversion elements 31 are electrically connected in series to each other, and the positive electrode terminal 32 and the negative electrode are respectively formed on the electrode layers of the photoelectric conversion elements 31 located at both ends in the lateral direction. The terminal 33 is formed. The positive electrode terminal 32 and the negative electrode terminal 33 are electrically connected to predetermined positions via connecting members.

Further, the photoelectric conversion element 31 is constructed so that light such as sunlight is incident from the main surface on the side opposite to the sheet-like substrate, that is, on the side facing the outside. The first electrode layer and the second electrode layer are made of a dielectric material, and serve as a pair of electrodes with respect to the photoelectric conversion layer. The photoelectric conversion layer is formed by including, for example, an amorphous semiconductor thin film represented by a pin junction structure of a-Si, and is configured to generate electromotive force when light such as sunlight is incident. It is formed of a film having a conversion effect.

The photoelectric conversion layer may have a pn junction structure formed of a p-type organic semiconductor such as perylene and an n-type organic semiconductor such as copper phthalocyanine. Note that the photoelectric conversion layer is not limited to the above-described thin film structure, and may be formed with a film structure having sufficient flexibility and a photoelectric conversion effect.

The first electrode layer is made of, for example, Ag, A
It is preferable that the photoelectric conversion layer is formed of a metal material such as 1, Cr, Ni, or Cu so as to have a high reflectance with respect to the light received by the photoelectric conversion layer. This allows
It is possible to improve the photoelectric conversion efficiency of the photoelectric conversion layer by reflecting the light transmitted through the photoelectric conversion layer and making it enter the photoelectric conversion layer again. The second electrode layer is preferably formed as a so-called transparent electrode formed of a material containing a metal oxide such as SnO ₂ or In ₂ O ₃ as a main component. Thereby, the light to be received by the photoelectric conversion layer can be efficiently transmitted, and the photoelectric conversion efficiency of the photoelectric conversion layer can be improved.

Further, in the photoelectric conversion sheet 3, each photoelectric conversion element 31 is arranged in parallel with the longitudinal direction thereof. That is, the pair of electrode layers of each photoelectric conversion element 31 are arranged so as to be parallel to the longitudinal direction of the photoelectric conversion sheet 3. Thereby, when the photoelectric conversion sheet 3 is stretched for photovoltaic power generation, even if a part of the photoelectric conversion element is not sufficiently irradiated with light, the power generation efficiency of the entire photoelectric conversion sheet decreases. It is possible to prevent that.

Specifically, for example, when the photoelectric conversion sheet 3 is stretched to generate photovoltaic power, this photoelectric conversion sheet 3 is used.
Since it has a long shape, it may be shielded by a shield so as to traverse the lateral direction. Even in this case, in the photoelectric conversion sheet 3, since each photoelectric conversion element 31 can sufficiently generate power in a portion where light is irradiated, and each photoelectric conversion element 31 is connected in series, The shielding effect of the photoelectric conversion elements 31 can be substantially evenly distributed in each photoelectric conversion element 31, so that sufficient electric power can be maintained at the positions of the positive electrode terminal 32 and the negative electrode terminal 33. Similarly, when the extension of the photoelectric conversion sheet 3 is incomplete and the light is shielded, the shielding effect of each photoelectric conversion element 31 is evenly distributed to each photoelectric conversion element 31. In addition, when the photoelectric conversion sheet 3 is curled by being stretched and unevenness of incident light occurs,
By evenly distributing the amount of light received by each photoelectric conversion element 31, it is possible to minimize a decrease in power at the positions of the positive electrode terminal 32 and the negative electrode terminal 33.

Further, the photoelectric conversion sheet 3 includes the winding core 2
It is wound around and is arranged so that it can be stretched freely.
One side, which is the innermost peripheral side, is connected and fixed to the winding core 2. In the photoelectric conversion sheet 3, the positive electrode terminal 32 and the negative electrode terminal 33 described above are electrically connected to one side on the innermost peripheral side. Here, the end portion of the photoelectric conversion element 31 of the photoelectric conversion sheet 3 is in a stretched state, and the inner end portion of the effective portion of the photoelectric conversion element 31 in the photoelectric conversion sheet 3 is outside of a position that is not substantially shielded from light in the pulled-out state. The presence of the element can prevent a decrease in power generation efficiency. Therefore, the photoelectric conversion element 31 is provided in the photoelectric conversion sheet 3 from a position where one side, which is the innermost peripheral side of the photoelectric conversion sheet 3, is fixedly connected to the winding core 2 to a position where it is not substantially shielded from light in the pulled-out state. Without, positive terminal 3
2 and the sheet portion 34 having the negative electrode terminal 33 are interposed.
Further, although the locking portion 30 is formed at the outermost peripheral end of the photoelectric conversion sheet 3, the photoelectric conversion element 31 of the photoelectric conversion sheet 3 is formed.
The outer end of the effective portion of the photoelectric conversion element 31 in the photoelectric conversion sheet 3 in the extended state is inside the position that is not substantially shielded by the locking portion 30 in the extended state. By doing so, it is possible to prevent a decrease in power generation efficiency. Therefore, the photoelectric conversion sheet 3 is provided with the photoelectric conversion element 31 from one position, which is the outermost peripheral side of the photoelectric conversion sheet 3, to a position where it is not substantially shielded from the connection fixing position of the locking portion 30 in the pulled-out state. The non-sheet portion 35 is interposed. Further, in FIG. 2, in the photovoltaic device having an outer peripheral wall 11 to be described later, the photoelectric conversion sheet connected and fixed to the winding core portion 2 so as to be sufficiently outside the slit 11a of the outer peripheral wall 11. No photoelectric conversion element 31 is provided in the photoelectric conversion sheet 3 from one innermost side of the photoelectric conversion sheet 3 to the end portion of the photoelectric conversion element 31 of the photoelectric conversion sheet 3 on the inner peripheral side, and the positive electrode terminal 32 is provided.
And the sheet portion 34 having the negative electrode terminal 33 is interposed. Thereby, in the charging operation, it is possible to prevent the light shielding of the outer peripheral wall 11 of the photoelectric conversion element 31 due to insufficient extraction. Furthermore, the photoelectric conversion element 31 from the inner circumference with a high curvature is
It can be moved to the outer peripheral side having a lower curvature, and fatigue deterioration due to bending of the photoelectric conversion element 31 can be reduced.

In the present invention, the photoelectric conversion sheet 3 is used.
Of the photoelectric conversion element 31 from the inner end of the effective portion of the photoelectric conversion element 31 to the inner end of the photoelectric conversion sheet 3, and from the outer end of the effective portion of the photoelectric conversion element 31 of the photoelectric conversion sheet 3 to the photoelectric conversion sheet. The sheet portion 35 extending to the outer end portion has substantially the same bending elasticity as the effective portion of the photoelectric conversion element 31. In this case, substantially the same means that the seat portion 34
It means that the difference in bending elasticity between the sheet portion 35 and the photoelectric conversion element 31 is within about 10%. In order to satisfy such conditions, the seat portion 34 and the seat portion 35
It is preferable that the layer structure of is substantially the same as that of the photoelectric conversion element 31. As a result, no bending occurs at the joint between the sheet portion 34 and the sheet portion 35 and the effective portion of the photoelectric conversion element 31. Thereby, the photoelectric conversion sheet 3 is evenly wound, and the use durability of the photoelectric conversion sheet 3 is improved.

Further, at the joint between the sheet portion 34 having the positive electrode terminal 32 and the negative electrode terminal 33 and the effective portion of the photoelectric conversion element 31, bending occurs, and the positive electrode terminal 32 and the negative electrode terminal 3 are formed.
In Fig. 3, bending is concentrated on a bent portion which is a joint between the sheet portion 34 and the photoelectric conversion element 31, and the fatigue of the terminal material is concentrated, which easily causes disconnection. Further, also in the photoelectric conversion sheet 3 as a whole, bending occurs at the seam between the sheet portion 34 and the sheet portion 35 and the effective portion of the photoelectric conversion element 31, and the fatigue of the material is concentrated in this portion, and breakage easily occurs. . In order to improve such a problem, the photoelectric conversion element 3 is formed over the entire surface of the photoelectric conversion sheet 3.
It is preferable that the effective portion of No. 1 and the sheet portion 34 and the sheet portion 35 have the same layer configuration. Electrical connection and insulation between the effective portion of the photoelectric conversion element 31 and the other portions (sheet portions 34 and 35) can be performed by making full use of a normal semiconductor process. For example, first, the same layer structure is manufactured using a normal semiconductor process, and then the photoelectric conversion element 31 is manufactured.
Of the sheet (34)
By irradiating a laser beam or the like on a boundary portion between the photoelectric conversion element 31 and the other portions (sheet portions 34 and 35), electrical connection can be cut off.

Further, it is preferable that the photoelectric conversion sheet 3 is arranged in such a state that the photoelectric conversion sheet 3 is wound around the winding core portion 2 so that its light receiving surface is inside. As a result, the photovoltaic device 1
When the photoelectric conversion element 31 is wound around the winding core 2 and held, the light receiving surface of the photoelectric conversion element 31 is not exposed to the outside, and the light receiving surface is damaged or damaged. Can be prevented.

In the present embodiment, the photoelectric conversion element 31 is wound around the winding core portion 2 so that the light receiving surface of the photoelectric conversion element 31 is placed inside. The present invention is not limited to this. For example, the photoelectric conversion element 31 may be wound around the winding core portion 2 so that the light receiving surface thereof faces the outside.

Further, the photovoltaic device 1 used in the accessory for photovoltaic device according to the present invention has a discharge voltage of about 0.6-1.
It is preferably about 9V. Accordingly, the photovoltaic device 1 used in the accessory for photovoltaic device according to the present invention can be used for an electrical or electronic device that uses a normal tubular standard battery as a power source, when the electrical or electronic device is used as a power source.
