Abstract

PURPOSE:To obtain a solar battery module, which also serves a role of a roofing tile in combination, by providing one of positive and negative electrodes on a light receiving side and the other on the back side, forming one electrode as a convex shape and the other as a concave shape, overalpping neighoring modules in tile shapes, coupling the convex and concave electrodes, and connecting the electrodes electromechanically. CONSTITUTION:Two modules have positive or negative convex electrodes 3' and concave electrodes 4' facing the electrodes 3' and are overalpped in the tile states. The convexes electrode is coupled at a part 9, and the connection can be made. This solar battery module has a structure, which can serve the role of a roofing tile and can be readily connected. This structure is not limited to the series connection, but can be applied to the perallel connection, when the protruded and recessed electrodes are provided on the positive and negative electrodes.

Description

[Detailed description of the invention] The present invention relates to a solar cell module.

In recent years, solar cells have begun to be seen as an energy source that can replace commercial electricity, not just for special purposes in remote areas.

Among these, general household use is considered to be the field with the greatest potential.

The present invention takes the above situation into consideration and provides a solar cell module having a structure that also functions as a roof tile for a house.

In conventional solar cell modules, both the positive and negative electrodes are generally provided on one side of the module, especially on the back side, and when connecting multiple modules to obtain the desired power, each module must be connected to the same They were placed on a flat surface, and the positive and negative electrodes on the back were connected in series or in parallel with appropriate connection leads, such as cabtyre cables.

However, since solar cell modules having such a conventional structure are arranged and utilized without overlapping each other, they cannot be used as part of the roofing material of a house, especially for waterproofing purposes.

The solar cell module of the present invention has positive and negative electrodes,
One electrode is provided on the light-receiving surface side and the other is provided on the back surface side, and one electrode has a convex structure and the other has a concave structure. When connecting multiple modules, adjacent modules are stacked in a tiled shape, and the convex electrode By fitting recessed electrodes, it is electrically and mechanically connected and has a structure that can also serve as a roof tile.

The present invention will be described in detail below with reference to the drawings.

FIGS. 1(a) and 1(b) show examples of conventional solar cell module structures, with FIG. 1(a) being a sectional view of the module alone and FIG. 1(b) being a sectional view of the module connection. In FIG. 1(a), 3 is a positive or negative electrode, and 4 is an electrode paired with 3. In FIG. 1(b), 8 is a lead wire for connecting two modules in series. 1st
As seen in Figure (b), it is clear that there is a gap between these two connected modules, which eliminates the use of roof tiles.

Figures 2 fa) and (b) show examples of solar cell structures according to the present invention, and Figure 2 ia) shows a single module,
FIG. 2(b) is a sectional view when two modules are connected. In FIG. 2(a), 3' is a convex positive or negative electrode, and 4' is a concave electrode paired with 3'.

FIG. 2(b) is a diagram in which the two modules described above are stacked one on top of the other in a tile-like manner, and are connected by fitting the convex electrode and the concave electrode at the position 9. As is clear from FIG. 2(b), the solar cell module of the present invention has a structure that can also serve as a roof tile and is easy to connect.

In the example of FIG. 2, only the case of series connection is shown, but each of the positive and negative electrodes has a convex and a concave 'ii,
It is clear that the provision of poles also allows parallel connections in a similar manner.
