Problems solved by technology

[0002] At present, with the increase in the power demand for spacecraft power systems, single-junction solar cells have been difficult to meet the demand, and triple-junction gallium arsenide solar cells are more and more widely used in For aerospace power supplies, the layout design of single-junction solar cell arrays is difficult to meet the requirements of triple-junction solar cell arrays for residual magnetism and anti-static discharge. Therefore, the layout design method for triple-junction solar cell arrays is one of the key technologies of solar cell arrays. One is also a key technical problem to be solved

Embodiment 1

[0020] The layout method of the three-junction solar cell array adopts mirror mapping layout, multi-fold back and forth layout, and the layout method of the north and south wings is the same; the mirror mapping layout method is that each solar panel is divided into four sub-arrays, two sub-arrays completely symmetrical between them.

[0021] The multi-fold structure of the multi-fold back-and-forth arrangement is arranged on the solar panel in an S-shaped back and forth, which reduces the voltage between the cells. The layout of the same pattern of the north and south wings is a modular design, and the four sub-arrays on each solar panel are exactly the same.

[0022] figure 1 Among them, the pressing point is a part of the substrate, which plays the role of fixing and locking during transportation. The interconnection sheet is welded on the electrode of the solar cell, and is used to connect another sheet of battery to play the role of series connection. The bus bars are w...

Abstract

The invention relates to a distribution and arrangement method for a triple-junction solar cell array, and belongs to the technical field of solar cells. The distribution and arrangement method for the triple-junction solar cell array is characterized in that the solar cell array is arranged in mirror mapping mode, a mode of folding back and forth and a mode in which the south and north wings are arranged identically; the mirror mapping mode is realized by dividing each solar panel into four subarrays, wherein every two subarrays are totally symmetric. The distribution and arrangement method for the triple-junction solar cell array has the advantages of simpleness, high anti-irradiation capacity, low voltage between cells, electrostatic discharge prevention, strong interchangeability, wide application, high production efficiency and the like, and meets the requirements of the solar cell array on reliability and the like; remanence is reduced; and the triple-junction solar cell array is convenient to produce.

Description

technical field [0001] The invention belongs to the technical field of solar cells, in particular to a method for arranging sheets of a triple-junction solar cell array. Background technique [0002] At present, with the increase in the power demand for spacecraft power systems, single-junction solar cells have been difficult to meet the demand, and triple-junction gallium arsenide solar cells are more and more widely used in For aerospace power supplies, the layout design of single-junction solar cell arrays is difficult to meet the requirements of triple-junction solar cell arrays for residual magnetism and anti-static discharge. Therefore, the layout design method for triple-junction solar cell arrays is one of the key technologies of solar cell arrays. First, it is also a key technical problem to be solved. Contents of the invention [0003] In order to solve the technical problems in the known technology, the present invention provides a three-junction solar cell arr...
