Side view showing a conventional solar cell module

  Hereinafter, based on an accompanying drawing, a solar cell module concerning an embodiment of the invention is explained.

  FIG. 1 is an overall perspective view in which a solar cell module 10 according to an embodiment is disposed to face a rectangular glass window (transparent member) 16 that is already provided in a window opening 14 of a building 12. is there. FIG. 2 is an enlarged longitudinal sectional view showing a main part of the solar cell module 10 shown in FIG.

  The solar cell module 10 includes a rectangular solar cell module main body 18 and a support member 20. The solar cell module 10 is arranged on the indoor side of the building 12 with respect to the glass window 16.

  As shown in FIG. 2, the solar cell module body 18 includes a glass plate (transparent plate-like body) 22 and a plurality of single-sided light receiving power cells (solar power generation cells) arranged on the main surface 22 </ b> A of the glass plate 22. 24, 24... The single-sided light-receiving power generation cells 24, 24... Are disposed between two resin films 26, 28 having translucency. The durability of the solar cell module body 18 of the embodiment is enhanced by using the glass plate 22 as a transparent plate-like body.

  The resin films 26 and 28 are preferably PVB (polyvinyl butyral), EVA (ethylene vinyl acetate copolymer) or ionomer used as an intermediate film of laminated glass. The solar cell module body 18 has a resin film 26 laid on the main surface 22A of the glass plate 22 and rectangular single-sided light-receiving power generation cells 24, 24... Arranged in a grid pattern on the resin film 26. After the resin film 28 is laid on the single-sided light-receiving power generation cells 24, 24..., The resin films 26 and 28 are welded using an autoclave device. The number of the resin films 26 and 28 is not limited to two, but may be two or more.

  Moreover, the solar cell module main body 18 is arrange | positioned so that the light-receiving surface (main power generation surface) of the single-sided light receiving power generation cell 24 faces the glass window 16 side. As a result, the single-sided light receiving power generation cell 24 receives sunlight incident from the outside of the glass window 16 through the resin film 28 and generates power.

  Although the single-sided light-receiving power generation cells 24, 24,... May be directly disposed on the main surface 22A of the glass plate 22, the single-sided light-receiving power generation cells 24, 24 ... are disposed between the resin film 26 and the resin film 28. The single-sided light-receiving power generation cells 24, 24... Can be protected by the resin films 26, 28 by being sandwiched.

  The single-sided light-receiving power generation cells 24, 24... Are connected in series by interconnectors (not shown) soldered to each, and the current generated by the single-sided light-receiving power generation cell 24 is supplied to the solar cell module body 18. It is taken out to the outside through a terminal box (not shown) provided at the edge.

  Further, a low radiation film (Low-E (Low-emissivity)) 30 is formed on the other main surface 22B facing the main surface 22A of the glass plate 22, that is, the main surface 22B on the indoor side of the glass plate 22. ing. The low radiation film 30 has a function of reducing the emissivity of thermal energy by infrared rays. That is, since the low radiation film 30 has a performance that makes it difficult for heat to pass through, the low radiation film 30 has high heat shielding properties and heat insulation properties. By forming the low radiation film 30 having such characteristics on the other main surface 22 </ b> B of the glass plate 22, heat shielding performance and heat insulation performance can be added to the solar cell module body 18.

Examples of the low radiation film 30 include those mainly composed of tin oxide (SnO ₂ ) and those mainly composed of silver (Ag). Since the low radiation film mainly composed of silver is easily oxidized, the low radiation film 30 formed on the other main surface 22B of the glass plate 22 is preferably composed mainly of tin oxide. Needless to say, the low-emission film 30 is not necessarily required and may not be provided.

  The solar cell module main body 18 configured as described above is supported by the support member 20 so as to face the glass window 16 and is supported separately from the glass window 16. That is, the support member 20 of the embodiment supports the solar cell module main body 18 so as to face the glass window 16 and supports the solar cell module body 18 spaced from the glass window 16.

  Thereby, the solar cell module 10 of embodiment has the translucency which can be easily additionally installed with respect to the glass window 16. FIG.

  There is also a solar cell module in which the entire surface of the solar cell module body 18 is directly bonded to the glass window 16. However, this solar cell module cannot be denied that air enters between the solar cell module body 18 and the glass window 16 at the time of construction. After the construction, air bubbles are formed between the solar cell module body 18 and the glass window 16. Remains. For this reason, there exists a problem that the appearance on the external appearance of the glass window 16 worsens.

  On the other hand, in the solar cell module 10 of the embodiment, since the gap 32 is interposed between the solar cell module main body 18 and the glass window 16, the bubbles do not exist. The appearance looks better.

  Further, when the entire surface of the solar cell module body 18 is directly bonded to the glass window 16, the heat from the single-sided light-receiving power generation cell 24 generated when the single-sided light-receiving power generation cell 24 receives light and generates power is applied to the glass window 16. Communicate directly. In the case where the glass window 16 is float soda lime glass or netted glass, there is a concern that thermal cracking may occur in the glass window 16 due to the heat.

  In contrast, in the solar cell module 10 of the present invention, since the gap 32 is interposed between the solar cell module body 18 and the glass window 16, the heat generated in the single-sided light receiving power generation cell 24 is generated by the glass window 16. Therefore, the problem of thermal cracking can be solved. The gap 32 is preferably set to 5 mm or more. By setting the gap 32 to be 5 mm or more, the above-described thermal cracking can be surely prevented and heat can be prevented from being trapped in the gap 32, so that a decrease in power generation efficiency of the single-sided light-receiving power generation cell 24 can be prevented.

  Further, when the entire surface of the solar cell module main body 18 is directly bonded to the glass window 16, it is difficult to remove the solar cell module main body 18 from the glass window 16, so that it is difficult to restore the glass window 16 to its original state. Moreover, the solar cell module main body 18 and the glass window 16 may be damaged by the force generated at the time of removal, that is, the force for peeling the solar cell module main body 18 from the glass window 16.

  On the other hand, since the solar cell module 10 of the embodiment only needs to remove the solar cell module main body 18 from the support member 20 and then remove the support member 20 from the building 12, the current state of the glass window 16 is restored. Work becomes easy. Further, since there is no force to peel off, the solar cell module body 18 and the glass window 16 are not damaged at the time of removal.

  Furthermore, in the solar cell module 10 according to the embodiment, the gap 32 interposed between the glass window 16 and the solar cell module body 18 is not sealed, so that when the glass window 16 receives wind pressure, The battery module body 18 is not subjected to a load of wind pressure. Thereby, even if the thickness of the glass plate 22 of the solar cell module main body 18 is reduced, there is no problem in the durability of the solar cell module main body 18. That is, the solar cell module main body 18 can be configured without considering the strength and bending of the solar cell module main body 18.

  Next, the form of the support member of the present invention will be described.

  First, a plurality of forms of support members described below are members that support the solar cell module body 18 in the vertical direction. Therefore, it is assumed that the glass window 16 is disposed in the window opening 14 in the vertical direction.
