Description

Technical Field

[0001] The utility model relates to the technical field of aerospace power supply, in particular to an interconnection sheet connected with ITO glass cover sheet electrodes. Background Art

[0002] In recent years, the number of satellites that conduct global space electromagnetic fields, ionospheric plasma, and high-energy particle detection to obtain space electromagnetic and ionospheric information has increased year by year. The necessary condition for in-situ detection of plasma and electromagnetic fields is that the interference of satellites on space detection objects should be reduced to an unobservable level, that is, the satellite is "invisible" relative to the plasma. This requires that the surface of the solar cell array be equipotential. To achieve the purpose of equipotential, it is necessary to paste ITO glass cover sheets on the solar cells. The traditional interconnection sheet structure does not match the ITO glass cover sheet electrode structure and cannot be used as an ITO glass cover sheet electrode interconnection sheet.
