Description

[Detailed description of the invention] The present invention relates to windows incorporating solar cells.

2. Description of the Related Art In recent years, the use of solar energy has attracted attention due to the demand for energy conservation, and one method of its use is a method in which sunlight is received by a number of photovoltaic cells, converted into electrical energy, and then used.

In order to convert solar energy into electrical energy and use it, generally a large number of photovoltaic cells that are electrically connected to each other are arranged in a plane, sandwiched between protective covering materials such as glass plates, and then glued together. , or a photovoltaic cell constructed in a flat plate, such as one in which a conductive film is directly coated on a cover glass, a thin semiconductor layer is applied to the surface of the film by printing, spraying, sputtering, plasma decomposition, etc., and an electrode is attached to the back side. A panel is used.

Photovoltaic panels like the one above are installed on the roof of a building, on a mount on the roof, or on the ground, and they convert sunlight energy into electricity to provide lighting inside the building.

If used as an alternative on a practical scale, such as air-conditioning/heating machine operation or elevator operation, a vast sunlight receiving area would be required.
- Blade The taller the building, the smaller the ratio of rooftop area to total floor area. Therefore, even if such photovoltaic panels are closely arranged over the entire rooftop area, the power obtained is relatively small and is not economically practical.

The present invention solves the above-mentioned conventional problems and provides a window with built-in solar cells that effectively utilizes a wide window space to install solar cells there and does not impair the transparency of the window. be.

That is, the gist of the present invention is that a large number of elongated plate-shaped photovoltaic panels are arranged in a window opening with their light-receiving surfaces facing horizontally or diagonally upward and spaced apart from each other by a phase t1-.

In the present invention, the photovoltaic panel can be fixed to a window glass or window frame in a horizontal position or at an angle within a range where a sufficient amount of light can be transmitted.

In addition, by attaching the photovoltaic panel to the light-shielding blade of the blind or using the photovoltaic panel itself in place of the light-shielding blade of the blind, the inclination angle can be adjusted steplessly in the direction in which the amount of transmitted light changes, that is, from vertical to horizontal. You can also do it.

If the angle is adjustable in this way, the photovoltaic cells can be held perpendicular or near perpendicular to the direct sunlight for a long period of time depending on the solar altitude, resulting in very good light receiving efficiency and the advantage that it can also be used with blackout blinds. .

The photovoltaic panel according to the present invention may be provided on the outside or inside of the window glass.

Further, as a preferred embodiment, a structure can be adopted in which double panes of inner and outer windows are provided at intervals to prevent contamination of the light-receiving surface, and a photovoltaic panel is provided in the airtight space between the two glasses.

When installing double window glass with a photovoltaic panel arranged between them as described above, instead of assembling the window glass and photovoltaic panel one after another at each installation site, the photovoltaic panel can be fixed at a predetermined angle or the angle can be changed freely. Alternatively, double-glazed glass with a built-in photovoltaic panel may be manufactured on a stock basis, and this double-glazed glass with a built-in photovoltaic panel may be attached to a window frame. The solar cell built-in window of the present invention can be installed not only on the south side of a building but also on the east and west sides.

According to the present invention, it is possible to convert direct solar light and sky-scattered light that shines on the vast window area of a high-rise building into electricity, significantly increasing the replacement rate of solar energy for the electricity used in the pill compared to conventional methods. It is possible to achieve remarkable energy saving effects.
