Problems solved by technology

However, in such a conventional structure, due to the difference between the bus bars and the interconnection ribbons formed on the front surface of the solar cells disposed at the lower side and the bus bar electrodes formed on the rear surface of the solar cells disposed at the upper side, Thickness, so that a relatively large gap is formed between overlapping parts, so there is a problem of easily damaging the solar cell or generating cracks when an external force such as impact or pressure is applied

Embodiment Construction

[0047] Hereinafter, a solar cell module according to an exemplary embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0048] Figure 1 to Figure 3 A solar cell module 1 according to the invention is shown.

[0049] refer to Figure 1 to Figure 3 , the solar cell module 1 according to the present invention includes a plurality of solar cells 100, a supporting portion 140, an interconnection ribbon 150, a transparent substrate (for example, tempered glass) configured to protect the front surface of the solar cells 100, arranged to surround the solar cells 100 The upper protective layer and the lower protective layer and the backplane and the frame 5 arranged under the lower protective layer.

[0050] The solar cell 100 is arranged such that a specific area of ​​the front surface of the edge of the solar cell 100 on one side overlaps a specific area of ​​the rear surface of the edge of the solar cell 100 on the other si...

Abstract

The present invention relates to a solar cell module and, more specifically, to a solar cell module in which one part of solar cells is overlapped such that the space occupancy rate of the solar cellscan be increased, and safety and structural problems occurring due to the overlapped solar cells can be solved. The solar cell module according to the present invention has a predetermined part of the solar cells overlapped and thus enables reduction of a non-generating area and increase in the space occupancy rate of the solar cells, thereby increasing the generation efficiency. By means of reducing the overlapped part of the solar cells, incidences of cracks and damage of the solar cells due to an external force are markedly decreased and thus stability and structural performance can be enhanced.

Description

technical field [0001] The present invention relates to a solar cell module, and more particularly, to a solar cell module in which solar cells are arranged to partially overlap each other to improve space occupancy of the solar cells and to be able to solve safety and structural problems caused by arranging the solar cells to overlap each other Problems with solar modules. Background technique [0002] A solar cell converts solar energy into electrical energy using a photoelectric conversion effect, and one solar cell generates small power of the order of several watts (W). Therefore, in order to obtain a desired output, a plurality of solar cells are set and arranged in a specific pattern and connected in series or in parallel, and then a waterproof solar cell module is used. [0003] Generally, in a solar cell module, glass is provided on its front surface, and an ethylene vinyl acetate (EVA) sheet and string lines are provided on its rear surface. In addition, an EVA s...
