Embodiment Construction

[0035] The core of the present invention is to provide a solar cell assembly. In the prior art, the cut battery pieces are usually rectangular or quasi-rectangular, that is, the battery pieces include long sides and short sides. Usually, adjacent cells are connected in series with their long sides overlapping to make a cell string. Since the length of the long side of the battery sheet is usually relatively long, the length of the long side of the battery sheet is usually 2 to 10 times the length of the short side. It will cause a large area of ​​coverage, and the covered part will not be able to absorb light to generate electricity, but will only consume electricity to generate heat, so it will cause a large current loss. At the same time, in the prior art, when cutting a galvanic cell into small cells, the cutting is usually performed along a busbar line provided on the galvanic cell, that is, the long side of the cell is the cutting surface. In the process of cutting, it ...

Abstract

The invention discloses a solar cell module. The surface of either short edge of the light receiving side of each cell overlaps and contacts the surface of the other short edge of the shaded side of an adjacent cell along the length direction of the cell to form a cell string through series connection, that is, the cells are connected in series through overlapping of the short edges. The area of the overlapping portions between the cells can be reduced, and the current loss between the cells can be reduced. Meanwhile, the effective light absorption area is increased, and the amount of generated power can be increased. Moreover, because the short edges of the cells are usually not the cutting surfaces, the overlapping of the short edges will not cause hidden crack, cell breakage or other risks, and the yield of the solar cell module can be improved.

Description

technical field [0001] The invention relates to the field of new energy, in particular to a solar cell assembly. Background technique [0002] With the continuous innovation of crystalline silicon solar cell technology, the current related cell technology has also been significantly developed, among which the shingled technology is a more popular technology to improve the luminous efficiency of solar modules. [0003] The various cells of a traditional solar cell module are connected by bus bars. The use of a large number of bus bars will increase the internal consumption of the solar module, and form between the cells that cannot be used to convert light energy into electrical energy. blank area, thereby reducing the conversion efficiency of the solar cell module. [0004] In layman's terms, the shingling technology is to reasonably cut the battery into small pieces, and then weld the cut small pieces into a battery string according to the pre-designed shingling process, a...
