Description

[Detailed description of the invention] A solar cell is made by depositing a conductive film, an amorphous silicon film, etc. on a substrate. Therefore, if you try to make a single sheet with a large area, the equipment will be large, and it is technically difficult to form a homogeneous deposited film on a large area, so the price will be higher than that of a sheet with a small area. It is inevitable that it will happen.

An object of the present invention is to enable advantageous use of small-area, relatively inexpensive solar cells by supporting a large number of small-area solar cells in the form of tiles.

In order to achieve this objective, the present invention fits the periphery of a plate-shaped solar cell into the inner groove of a frame having a partition made of elastic rubber, fits the frame into the outer groove of the frame, and connects the inner groove with the frame. A zipper string is fitted into a zipper groove formed on the middle side surface of the outer groove to support the solar cell.

To explain one embodiment shown in FIGS. 1 and 2, 1 is a plate-shaped solar cell, 2 is a frame made of elastic rubber, and has a partition 3. FIG. An annular inner groove 4 is continuously provided on the inner side of the frame 2 and the partition 3, and an outer groove 5 is provided on the outer periphery of the frame 2.
Reference numeral 6 denotes a zipper groove provided on the side surface between the inner groove 4 and the outer groove 5 of the frame 2 and the partition 3, and is provided to make it easier to open the inner groove 4 and the outer groove 5. A zipper string 7 made of elastic rubber and having the same cross-sectional shape as the zipper groove 6 is fitted into the zipper groove 6 to prevent the inner groove 4 and outer groove 5 from opening and to fit the inner surfaces of these grooves into the groove. This is to ensure that it is well crimped with the matching item.

In this case, the periphery of the solar cell 1 is fitted into the inner groove 4,
A frame 8 is fitted into the outer groove 5, a zipper string 7 is fitted into the zipper groove 6, and the solar cell 1 is supported by the frame 8 via the frame 2 and its partition 3.

A groove 9 having a T-shaped cross section is provided on the side surface of the inner partition 3 opposite to the zipper groove 6, and a reinforcing frame 10 having a T-shaped cross section is fitted into the groove 9 to reinforce the inner partition 3. It can also be connected to the frame 8.

FIG. 3 shows that instead of providing grooves 9 in the inner partition 3, protrusions 11 having grooves are formed facing each other, and L-shaped reinforcing frames 12 are fitted into the grooves of the protrusions 11 from both sides.
Although a modification is shown in which the protrusions 11 are held between them, the protrusions 11 may be press-fitted into the grooves of the reinforcing frame 12 and held therein.

In order to protect the light-receiving surface of the solar cell 1, even if a transparent glass layer is placed on the light-receiving surface or an insulating plate is placed on the back surface of the solar cell 1, the structure of the present invention simply overlaps the solar cells 1 and a large number of them in the frame 2. It can be easily held together like a tile, and a large number of small-area solar cells can be assembled into one assembly at low cost. Of course, this proposal is not limited to supporting small-area solar cells.
Furthermore, since the back surface can be sufficiently opened and heat dissipation from the back surface is good, temperature rise can be reduced and power generation efficiency can be improved. In addition, since the solar cells are held through frames and partitions made of elastic rubber, they have excellent earthquake resistance and wind pressure resistance, absorb distortion of the frame due to differences in temperature, and can easily be used as support devices with excellent waterproof and moisture-proof properties. It can be configured as follows.
