It is connected to the transparent electrode layer 103 via an electrical connection portion.

As shown in FIG. 2, an electronic component 5 is provided in the housing 1 in which the photoelectric conversion element 100 is arranged. In the present embodiment, the electronic component 5 is provided at a predetermined position on the ceiling portion 23 of the housing 1 (main body 2).
The electronic component 5 may be a component having any function, but is preferably a component including at least one of a detector, a transmitter, a light emitting element, and a display element.

For example, by using an electronic component 5 including a detector (sensor) that detects the amount of dust (filling amount) and a transmitter that transmits the information, it is possible to accurately know the appropriate timing for collecting dust. Therefore, it is possible to reduce the waste collection cost.
As shown in FIG. 2, a pair of band-shaped component-side terminal portions 71 and 72 are provided along the vertical direction (height direction) at positions on both the left and right sides facing the opening 212 of the housing 1. There is. The component side terminal portion 71 is connected to the electronic component 5 via the fixed wiring 61, and the component side terminal portion 72 is connected to the electronic component 5 via the fixed wiring 62.
As shown in FIG. 5, the fixed wirings 61 and 62 are provided on the inner surface of the housing 1 (main body 2), respectively.

Further, as shown in FIGS. 5 and 6, a pair of guide rails (guide portions) 91 and 92 are provided at positions corresponding to the component side terminal portions 71 and 72 on the inner surface of the housing 1 (main body 2).

Opposing edge portions of the photoelectric conversion element 100 (portions provided with element-side terminal portions 81 and 82) can be inserted into the guide rails 91 and 92. The photoelectric conversion element 100 can be guided into the housing 1 by sliding the photoelectric conversion element 100 along the guide rails 91 and 92 and vertically upward.

Then, when the photoelectric conversion element 100 is arranged in the housing 1, the photoelectric conversion element 100 is generated by the contact between the corresponding component-side terminal portions 71 and 72 and the element-side terminal portions 81 and 82. Electric power can be supplied to the electronic component 5.
According to such a configuration, for example, when the photoelectric conversion element 100 fails or reaches the end of its life, the photoelectric conversion element 100 can be easily replaced. Further, since the contact area between the component-side terminal portions 71 and 72 and the element-side terminal portions 81 and 82 can be increased, the resistance can be reduced. As a result, the electric power generated by the photoelectric conversion element 100 can be used without waste.

The component-side terminal portions 71 and 72 may be provided on the inner side surfaces of the guide rails 91 and 92, respectively. For example, when the component side terminal portions 71 and 72 are provided on the inner side surface extending in the direction parallel to the opening 212 of the guide rails 91 and 92, the photoelectric conversion element 100 may be used by inverting the front and back, or the element side terminal portion 81. The 82 may be formed so as to be exposed on the second substrate 102 side. Further, when the component side terminal portions 71 and 72 are provided on the inner side surface extending in the direction orthogonal to the opening 212 of the guide rails 91 and 92, the element side terminal portions 81 and 82 may be formed on the side surface of the photoelectric conversion element 100. ..

The constituent materials of the component-side terminal portions 71 and 72 and the element-side terminal portions 81 and 82 are metal materials such as gold, silver, copper, platinum, aluminum, tantalum, molybdenum, chromium or an alloy containing these, respectively. Examples thereof include conductive oxide materials as described above, carbon blacks, carbon nanotubes, carbon materials such as fullerenes, and conductive organic materials such as polyacetylene, polypyrrole, and PEDOT / PSS. These materials may be used alone or in combination of two or more.
The thicknesses of the component-side terminal portions 71 and 72 and the element-side terminal portions 81 and 82 are not particularly limited, but are preferably about 0.05 to 12 mm, more preferably about 0.1 to 7 mm. ..

Further, as shown in FIG. 5, a contact member (for example, a stainless steel plate or the like) 93 having a substantially L-shape is provided at an upper position facing the opening 212 of the housing 1.
When the photoelectric conversion element 100 is guided into the housing 1 via the guide rails 91 and 92, the upper end portion of the photoelectric conversion element 100 comes into contact with the contact member 93, so that the casing of the photoelectric conversion element 100 comes into contact with the contact member 93. Positioning with respect to the body 1 is made. That is, the contact member 93 constitutes a positioning unit for positioning the photoelectric conversion element 100 with respect to the housing 1 in a state where the photoelectric conversion element 100 is arranged in the housing 1.

Further, the trash can has a screw (pressing portion) 200 as shown in FIG. With the photoelectric conversion element 100 arranged in the housing 1, the screws 200 are passed through the guide rails 91 and 92 and tightened to the housing 1 (body portion 21). As a result, the element-side terminal portions 81 and 82 can be pressed toward the component-side terminal portions 71 and 72. As a result, more reliable conduction between the element-side terminal portions 81 and 82 and the corresponding component-side terminal portions 71 and 72 can be achieved.
By connecting the tip of the screw 200 to the guide rails 91 and 92 and tightening the screw 200, a part of the guide rail 91 and 92 is deformed or displaced, and the deformed or displaced portion deforms or displaces the element side terminal portion 81. The 82 may be pressed toward the terminal portions 71 and 72 on the component side.

The number of screws 200 to be used is appropriately set according to the lengths of the terminal portions 71 and 72 on the component side, and is not particularly limited, but is preferably about 2 to 9, and preferably about 3 to 7. Is more preferable.
The pressing portion is not limited to the screw 200 as long as the element-side terminal portions 81 and 82 can be pressed toward the component-side terminal portions 71 and 72, and the pressing portion is not limited to the screw 200, for example, a combination of a coil spring and a spring seat. And so on.

Here, the photoelectric conversion element 100 may be an inorganic photoelectric conversion element in which the photoelectric conversion unit is made of a silicon material. Since the inorganic photoelectric conversion element has excellent durability, the number of replacements of the photoelectric conversion element 100 can be reduced by using the inorganic photoelectric conversion element.
However, the photoelectric conversion element 100 as described above, that is, an organic photoelectric conversion element using an organic material for at least a part of the photoelectric conversion unit (for example, an organic thin film solar cell, a perovskite type solar cell, a dye sensitized solar cell, etc.) ), Although it is inferior in durability to an inorganic photoelectric conversion element, it is lightweight and resistant to damage. Therefore, the organic photoelectric conversion element is suitable for use in the present invention, and the housing 1 can be used for a long period of time by replacing the photoelectric conversion element 100.

<Second Embodiment>
Next, a second embodiment of the trash can using the storage container of the present invention will be described.
Hereinafter, the second embodiment will be described mainly on the differences from the first embodiment, and the description thereof will be omitted for the same matters.
The second embodiment is the same as the first embodiment except that the arrangement position of the element-side terminal portion in the photoelectric conversion element is different.

FIG. 7 is a perspective view showing the configuration of the photoelectric conversion element according to the second embodiment, and FIG. 8 is a view corresponding to FIG. 6 of the second embodiment.

"Upper" and the back side of the page are called "lower side" or "lower side".

In the photoelectric conversion element 100 shown in FIG. 7, a step portion 300 is formed along the left and right edge portions (opposing edge portions) thereof. In the present embodiment, the element-side terminal portions 81 and 82 are housed in the step portion 300.
The depth of each step portion 300 is set to be substantially equal to or slightly smaller than the total thickness of the component side terminal portions 71 and 72 and the element side terminal portions 81 and 82. As a result, with the photoelectric conversion element 100 arranged in the housing 1, more reliable conduction between the element-side terminal portions 81 and 82 and the corresponding component-side terminal portions 71 and 72 can be achieved.

Further, according to such a configuration, when the photoelectric conversion element 100 is guided into the housing 1 via the guide rails 91 and 92, the component side terminal portions 71 and 72 are inserted into the corresponding stepped portions 300. Therefore, it is possible to prevent the photoelectric conversion element 100 from being displaced in the horizontal direction (left-right direction) with respect to the housing 1 (main body 2). Therefore, the photoelectric conversion element 100 can be inserted more smoothly into the housing 1.
Also in the second embodiment as described above, the same actions and effects as those in the first embodiment can be obtained.

Although the storage container of the present invention has been described above, the present invention is not limited thereto. The storage container of the present invention may have any other configuration or may be replaced with any configuration that exhibits a similar function.

Further, the position of the photoelectric conversion element 100 (guide rails 91 and 92) may be the bottom portion 22 or the ceiling portion 23 instead of the body portion 21 of the housing 1.
Further, the housing 1 may be composed of a main body 2 having an upper opening and a lid 3 attached to the main body 2 so that the upper opening can be opened and closed. In this case, the position of the photoelectric conversion element 100 (guide rails 91 and 92) may be the lid 3.

The pair of guide rails 91 and 92 may be provided along a curved surface, not limited to a flat surface. Even in this case, since the organic photoelectric conversion element has flexibility, it can be smoothly guided in the housing 1 by the pair of guide rails 91 and 92. The guide portion may be formed of a U-shaped frame instead of the pair of guide rails 91 and 92.
Further, the opening 212 may be opened by omitting the installation of the sealing member 4. That is, the photoelectric conversion element 100 may be exposed to the outside of the housing 1 at the opening 212.
Further, a partition wall may be provided in the housing 1 to partition the space for accommodating the photoelectric conversion element 100 and the space for accommodating dust.
The planar view shape of the photoelectric conversion element 100 is not limited to a quadrangular shape, and may be, for example, a polygonal shape other than a quadrangular shape such as a triangular shape or a hexagonal shape, a circular shape, an elliptical shape, or the like.

Further, the shape of the body portion 21 may be, for example, a cylindrical shape, an elliptical tubular shape, or the like. Even with the body portion 21 having such a shape, since the organic photoelectric conversion element has flexibility, it can be arranged in a curved state.
The storage container can be used not only for a trash can, but also for a mailbox, a delivery post, a security sensor, a document box, a water tank, and the like.
