| Abstract: |
| Objective To improve the reliability of the solar cell arrays. Methods The electrostatic protection technology of GEO/MEO orbit solar cell arrays was studied. Primary arc simulation test was carried out on the solar cells by an external arc. The secondary arc of solar arrays was tested in the environment of quasi multispectral energy. Results The primary arc had no influence on the solar cells. The threshold of the voltage between the series of solar cells was 80 V when the secondary arc occurred. Secondary arc affected the output power of the solar cells to a certain extent. Conclusion During the design of solar cell arrays, the solar cell arrays can be effectively controlled if the parallel gap between the solar cell strings is controlled at 1 mm, the voltage difference between the adjacent solar strings is not more than 80 V, and the silicon rubber is applied between the adjacent solar strings. It can improve the reliability of the solar cell arrays greatly. |
