  As illustrated, the solar cell 10 with a display unit of the present invention has a condensing surface 12 of the solar cell panel 11 having a condensing surface 12 for concentrating sunlight as defined in the device of claim 1. A light-transmitting display member 20 that transmits sunlight and has a printed display surface P is disposed on the front surface.

  The solar cell panel 11 is also referred to as a solar cell module, and is used in a power generation system that uses solar cells and directly converts solar energy into electric power. In general, a crystalline silicon type solar cell is integrated, fixed with an aluminum frame, and glass is stretched on the surface. Since the power that can be generated by a single solar panel is limited, it is usually installed side by side. The generated electricity may be connected to the power grid or may be used alone without being connected. It is well known that it is also used in artificial satellites and space stations.

In this device, a light-transmissive display member 20 having a printed display surface P is disposed on the front surface of the light collecting surface 12 of the solar cell panel 11. In general, it is common sense not to place anything that interferes with the light collection efficiency on the front surface of the light collecting surface 12 of this type of solar cell panel 11. However, it does not matter if it does not transmit light at all, and in the case of many things, and in the case of sheet-like materials and thin planar structures, it does not naturally emit any light other than those that have significantly improved light shielding performance. It has the property of passing through. Furthermore, for example, in the sheet industry, there are those that have light transmission performance of 80%, 90% or more of light transmission. If so, by arranging the light transmissive display member 20 on which the print display surface P is formed, the effect of forming a larger display portion, that is, the improvement in landscape, than the slight decrease in light collection efficiency, If the advertisement function can be obtained, the usefulness as an article can be further enhanced.

Furthermore, if the idea is changed, it is possible to obtain a solar cell panel with high light collection efficiency while being a display member. That is, for example, if a solar cell panel is arranged on the back side of a display member (panel) that has been conventionally used for advertising or landscape, there is no need to secure a special place, and the state is kept as it is. This makes it possible to generate solar power. In other words, according to this device, the advertising panel can have a power generation function.

  As the light-transmitting display member 20, as defined in the invention of claim 2 and as shown in FIG. 2, it is possible to use a sheet-like material 21 having light transmitting holes h, h. Moreover, it is simple and advantageous in terms of cost. The sheet-like material 21 having a light transmitting hole that transmits sunlight is often used for outdoor advertisements, tents, banners, architectural sheets, and the like. For example, the trade name “Tarpo Canvas” (registered trademark) of Hiraoka Orizome Co., Ltd. is a 0.35 mm thick sheet made of a composite of a polyester base fabric and a vinyl chloride resin, and has excellent printing performance. By the way, the hole of this trade name “Tarpo Canvas” (registered trademark) is said to be for reducing the wind pressure that the sheet receives outdoors, but in this device, it also contributes to light transmission, The light collection efficiency when the sheet is arranged on the front surface of the light collection surface 12 of the solar cell panel 11 has at least 90% or more light transmittance as compared with the case where nothing is placed.

  For example, as shown in FIGS. 3 and 4, the light-transmissive display member 20 is attached and arranged by forming a eyelet 30 near the periphery of the display member 20 and pulling it with a rope 31. It can be fixed to the outer frame 15. This rope construction is a fixing means for outdoor advertisements, tents, banners, building sheets, etc., but for outdoor installation, inspection and replacement are easier than semi-permanent fixing means. This is preferable. In addition, it cannot be overemphasized that the display member 20 and the condensing surface 12 of the solar cell panel 11 are arrange | positioned keeping a clearance gap, without contacting.

  In addition, the light-transmitting display member 20 may be made of any material as long as it has light transmitting performance and can be printed. However, with regard to light transmission performance, it is desirable that the higher the transmittance, the higher the light collecting ability, and the fact that printing can be performed easily and reliably is an important effect of this device. In consideration of the above, the material and its configuration are selected.

FIG. 5 shows an example of the light-transmitting display member 22 in which a large number of elongated rod-like bodies 23, 23 are arranged in parallel in the shape of a bar. Reference numeral 24 denotes an outer frame member for attachment, and P denotes a print display surface. In addition, when forming the print display surface P on the light-transmitting display member 22 arranged in a bar shape as in this example, it is also possible to attach a film or the like on which the display portion is printed. FIG. 6 shows an example of the light-transmitting display member 25 made of the net 26. Reference numeral 27 denotes an outer frame member for attachment. The coarseness of the mesh 26 can be selected as appropriate.

As for the materials of the cross-like light-transmitting display member 22 and the mesh-like light-transmitting display member 25 shown in FIGS. 5 and 6 above, as defined in the invention of claim 4, synthetic resin or metal, or a combination of both It can consist of things. If the essence of this invention is not harmed, the material of the light transmissive display member may be fiber fabric, wood, ceramic or the like.

  As described above and as defined in the invention of claim 5, the printed display surface of the light-transmitting display member can be an advertising surface. In addition to the effect that the solar cell having a large advertising function, it has an extremely large practical effect that the existing advertisement surface can also have the solar cell function.

  FIG. 7 is an example of a solar cell 10A with a display unit of the present invention installed on the roof of a house. On the surface of the condensing surface of the solar cell, a printed display surface 20A made of a design pattern that takes the landscape into consideration is formed, which has an effect of improving the landscape of the condensing surface of the solar cell that tends to be tastelessly dried. . In particular, it is necessary to consider the landscape in an area where a large number of solar cell panels are arranged and occupy a huge area.

  FIG. 8 is an example of a solar cell 10B with a display unit of the present invention installed on an outdoor advertising board. A solar cell is used as a so-called standing signboard type outdoor advertising board. As described above, the existing outdoor advertising board can have a solar cell function.

  FIG. 9 is an example of a solar cell 10C with a display unit of the present invention installed on the wall surface of a large building. When the installation of the solar cell panel is hindered by design constraints such as the building landscape, it can be solved by arranging the display member of this device.
