Abstract

The invention discloses a vacuum degassing test method for a solar cell array. The method comprises the following steps: hanging a solar cell panel in a vacuum degassing box; setting working parameters of the vacuum degassing box; the vacuum degassing box is opened; and monitoring parameters of the solar panel. The solar cell array vacuum degassing test method provided by the invention is scientific, accurate and high in reliability, can guide the single-plate-level high-temperature degassing test of the solar cell array, improves the on-orbit reliability of the spacecraft solar cell array, and provides a scientific basis for formulating the vacuum high-temperature degassing test standard of the spacecraft solar cell array.

Description

technical field [0001] The invention belongs to the technical field of solar battery arrays, and in particular relates to a vacuum degassing test method for solar battery arrays. Background technique [0002] When a spacecraft operates in a plasma environment, the interaction between the high-voltage solar cell array and the plasma will cause electrostatic discharge, which mainly occurs between the glass cover, the interconnect and the plasma. When the potential difference between battery strings is higher than a certain threshold voltage, electrostatic discharge may cause continuous arc discharge (secondary discharge), which eventually leads to a permanent short circuit of the solar cell array. [0003] The surface of satellite solar cell array includes glass cover sheet, solar cell, metal interconnect sheet and base material. Cells are charged at different rates, resulting in unequal charge buildup resulting in electrostatic discharge (ESD). Experiments have shown that p...
