残光現象により受光効率の向上が図られてきた。2. Description of the Related Art In a conventional solar cell power supply device, in order to improve the light receiving efficiency, for example, the light receiving surface of the solar cell is made as perpendicular as possible to the incident direction of sunlight. The reflection of sunlight has been minimized. Furthermore, in a solar cell described in, for example, JP-A-53-33592, a molded body made of a transparent substance is arranged on a light receiving surface, and fine particles such as a phosphor and a phosphor are scattered and mixed in the molded body. The light receiving efficiency has been improved by the irregular reflection of light and the afterglow phenomenon.

構成が複雑になってしまう。However, in the conventional solar cell power supply device, the light receiving surface of the solar cell is made substantially perpendicular to the sunlight. There is a drawback that the device is large and the installation place is restricted. In addition, in order to always direct the light receiving surface at a right angle to sunlight, for example, it is necessary to provide a mechanism for moving the solar cell itself by using time as a variable to change the angle of the light receiving surface, which complicates the device configuration. turn into.

に向上させることは難しいという問題がある。Further, when a mold body containing a phosphor or a phosphor is arranged, incident sunlight impinges on the contaminant to cause irregular reflection or afterglow. Since the energy conversion can be performed for a certain period of time even when the power supply stops, it is possible to prevent the electrical output from immediately losing. However, in terms of improving the light receiving efficiency, for example, some of the light irregularly reflected upon the contaminant may be emitted to the outside without being irradiated on the light receiving surface. There is a problem that it is difficult to dramatically improve the light receiving efficiency of the solar cell simply by providing the light emitting element on the solar cell.

The sunlight that has entered the light guiding layer scatters light when it hits reflective substances scattered in the light guiding layer, or is reflected by a reflecting surface formed on a flat surface facing the light receiving surface of the solar cell. The light is irradiated almost uniformly on the light receiving surface of the battery, so that the solar cell converts light energy into electric energy.

By providing the semi-cylindrical condensing surface on one side of the light guiding layer in this way, sunlight irradiated from various directions can be effectively condensed by the condensing surface with a relatively small area to guide light. It can be made to enter the layer.

With respect to the light-guiding layer, reflecting light is formed on all surfaces except for the plane in contact with the light-receiving surface of the solar cell and one side on which sunlight enters, so that the sunlight incident on the light-guiding layer can be light-guided. It is confined in the layer and the light receiving surface of the solar cell is reliably irradiated.

It is sent into the resin layer 21 of the guideway 20. The solar cell power supply having the above-described configuration is, for example, when used fixedly outdoors as a power generator for a house or the like, so that the movement of the sun due to the rotation of the earth follows the circumference of the light-collecting surface.

In each of the light incident portions 30, the incident light is condensed by passing through a semi-cylindrical condensing surface, passes through a focus inside the condensing surface, and is sent into the resin layer 21 of the light guide path 20.

になる。The optical path of the incident light shown by the arrow line in FIG. 2 is for the case where the light travels straight through the resin layer 21 and reaches the light receiving surface of the solar cell 10 without being irregularly reflected by the reflective material. is there. Also, a state is shown in which a part of the light that has reached the solar cell 10 is reflected on the light receiving surface, the reflected light travels straight in the resin layer 21 and is reflected on the light reflecting surface 22. Actually, since the incident light is irregularly reflected by the reflecting material located on the illustrated optical path, the energy of the incident light traveling on the above optical path decreases as it goes deeper into the light guide path 20 (downward in FIG. 2). . The light irregularly reflected by the reflective material is further repeatedly irregularly reflected or reflected by the light reflecting surface 22 to be applied to the light receiving surface of the solar cell 10. For this reason,
As for the light reaching the light receiving surface located at the back of the light guide path 20, a large amount of light has passed through paths other than the above-described optical path, and as a result, the incident light condensed by the light incident section 30 Is almost uniformly irradiated on the light receiving surface of the solar cell 10.

When the light is irradiated on the light receiving surface of the solar cell 10 via the light guide path 20, the light energy is converted into electric energy (voltage) in each solar cell 10, and the electric energy is extracted from each electrode. Become like As described above, according to the solar cell power supply device of the present embodiment, sunlight emitted from an arbitrary direction is condensed by the light incident portion 30 and sent to one side surface of the resin layer 21 to be incident on the resin layer 21. The reflected light is reflected by a reflective substance or surface to irradiate the light-receiving surface of the solar cell almost uniformly. Even if the light is not directed vertically, the sunlight from each direction can be effectively guided to the light guide path 20 by the light incident portion 30 having a small area and irradiated on the light receiving surface of the solar cell 10. Energy conversion efficiency (light receiving efficiency) with respect to the light receiving area (the area of the light incident portion 30) can be significantly improved,
In addition, a small solar cell power supply can be provided. As a result, the productivity of the solar cell power supply device is improved, and the installation place of the device and the installation work are easy, and the construction cost can be reduced. In addition, since the flat surface facing the light receiving surface of the resin layer 21 and the side surface not facing the light incident portion 30 are formed as reflection surfaces, incident sunlight can be reliably confined in the resin layer 21. Higher efficiency can be achieved.

For example, as in the case of a conventional solar cell, a phosphor or a phosphor is mixed into the resin layer. May be. If a light emitter, a fluorescent material, or the like is mixed, the electric output is continued for a certain period of time even when the incident light is cut off. Although the light guide layer is formed using a transparent resin, the light guide layer may be formed of, for example, a transparent glass or the like in addition to the resin. Further, the semi-cylindrical condensing surface is used for the light incident part 30, but the configuration of the light incident means of the present invention is not limited to this, An application using a known device such as a condenser lens that can be incident on one side of the layer is also possible.
