Description

Sheet distribution method for battery array
Technical Field
The invention belongs to the technical field of solar cell arrays for space, and particularly relates to a method for distributing sheets of a cell array.
Background
The solar cells are uniformly distributed on the surface of the solar cell array substrate, and the purpose is to convert light energy into electric energy to supply power for the satellite. The solar cells adopted on the current solar cell array for space use are mainly rectangular solar cells with more regular shapes, and the epitaxial wafers of the rectangular solar cells have lower utilization rate and higher production cost. Polygonal solar cells are less used in space solar cell arrays and cannot be well adapted to a rectangular solar cell sheet distribution method. For this case, the following problems may occur if the conventional rectangular solar cell sheet method is used:
in the traditional method, the same type of cells are adopted for sheet distribution, the gaps among the solar cells are large, the sheet distribution rate is low, and each cell needs to be protected by adopting an independent diode. Undoubtedly, the effective sheet distribution area of the whole plate is reduced, the sheet distribution rate is reduced, and the cost of the solar cell is increased.
If the same large-size polygonal solar cell is used for sheet distribution, the gap between the edges of the solar cell spacing plates is larger at the edge of the substrate, and the sheet distribution rate is lower.
The rectangular solar cell is completely symmetrical in shape, and the uniform distribution of a plurality of cells and the sheet distribution on the surface of the substrate have poor adaptability and low sheet distribution rate.
