In recent years, with the rapid development of society, the demand for energy is becoming larger and larger. However, because of the limited reserves of traditional resources (such as coal, oil, etc.), scientists need to constantly explore new energy, such as the most well-known wind, solar, tidal energy, etc. As we all know, because of the long life of the sun, solar energy is considered as inexhaustible and inexhaustible new energy.
At present, triple junction GaAs solar cell is a widely used power supply in the space field. In recent years, the space industry in China has developed rapidly. The triple junction GaAs solar cell array, which provides energy for satellites, has been widely used in the space field. The number of satellites that have been used to detect the electromagnetic field, ionospheric plasma and high energy particles to obtain the information of space electromagnetic and ionosphere is increasing year by year. The necessary condition for in-situ detection of plasma and electromagnetic field is that the interference of satellite to the space detection object should be reduced to the degree of non observability, that is to say, the satellite is "invisible" relative to the plasma. This requires that the potential of the satellite be controlled within a certain range, usually ± 2V, that is, the "equipotential" in the patent.
At present, China has a deep understanding of the charge / discharge characteristics of satellite surface. However, for the gaas solar cell array surface with a large proportion of the satellite surface, especially for satellites with equipotential requirements, there is little research on potential control technology. The application of equipotential network technology in triple junction GaAs solar cell array is still a blank stage.
