no. 1 approach

[0046] figure 1 It is a schematic cross-sectional view showing the first embodiment of the frameless solar cell panel according to the present invention.

[0047]A frameless solar cell panel 1A ( 1 ) of the first embodiment includes a laminate 10 and a silicon-based sealing material 11 . In the laminated body 10, the transparent first base material 2, the power generation part 3, the sealing layer 4, and the back sheet 5 are laminated|stacked in this order. In addition, a silicon-based sealing material 11 is disposed on the side surface 10 a (end portion) of the laminated body 10 .

[0048] In the frameless solar cell panel 1A(1) of the first embodiment, by arranging the silicon-based sealing material 11 on the side surface 10a of the above-mentioned laminate 10, the weather resistance to ultraviolet rays (UV) or moisture is ensured, and the Sufficient rigidity for protecting the laminated body 10 . Accordingly, in the first embodiment, a solar cell panel having a frameles...

no. 2 approach

[0069] exist image 3 In , the same symbols are assigned to the same components as those in the first embodiment, and descriptions thereof are omitted or simplified.

[0070] exist image 3 In the shown frameless solar cell panel 1B ( 1 ), the silicon-based sealing material 11 covers at least the side surface 10 a of the laminate 10 and the outer edge 2 b on the outer surface 2 a of the first substrate 2 . The silicon-based sealing material 11 has a substantially L-shape in the cross section of the laminated body 10 .

[0071] Also in this configuration, the same effect as that of the first embodiment can be obtained.

no. 3 approach

[0073] exist Figure 4 In , the same symbols are assigned to the same components as those in the first embodiment, and descriptions thereof are omitted or simplified.

[0074] exist Figure 4 In the illustrated frameless solar cell panel 1C ( 1 ), an adhesive layer 12 made of butyl rubber is disposed between the silicon-based sealing material 11 and the laminate 10 . Butyl rubber has excellent resistance to water vapor transmission. Since the adhesive layer 12 is disposed, it is possible to more reliably prevent moisture and the like from entering the laminate 10 from the side face 10 a of the laminate 10 . Accordingly, the frameless solar cell panel 1C(1) having further excellent moisture resistance can be realized.

[0075] (Manufacturing method)

[0076] Next, a method of manufacturing the above-mentioned frameless solar cell panel will be described.

[0077] In the method of manufacturing a frameless solar cell panel, a laminate 10 in which a transparent first base ma...

Abstract

The frameless solar cell panel includes: a laminate (10) having an end portion (10a), and a first base material (2), a power generation portion (3), a sealing layer (4) and a back sheet are sequentially laminated (5) or the second substrate (6); and a silicon-based sealing material (11).

Description

technical field [0001] The present invention relates to a frameless solar cell panel and a method for manufacturing the frameless solar cell panel. [0002] this application claims priority based on Japanese Patent Application No. 2009-054253 for which it applied on March 6, 2009, and uses the content here. Background technique [0003] In recent years, solar cells have attracted more and more attention as an alternative energy source. [0004] In addition, cost reduction of solar cells is required, and solar cells using thin-film semiconductor materials such as amorphous silicon are attracting attention. [0005] Figure 8 It is a cross-sectional view showing an example of a conventional amorphous silicon solar cell panel (for example, Patent Document 1). [0006] Such as Figure 8 As shown, the solar cell panel 112 includes: a glass substrate 100 and a solar cell layer (power generation layer) 102 formed on the back surface of the glass substrate 100 and made of amorphou...
