However, there are some technical problems as using high voltage in the solar power system. In the space environment, electric discharges occur on the solar cell arrays and the discharges cause damage to the arrays and the efficiency falls. Therefore, it is important to work out to these problems for developing the application in the space. There are two causes in the electric discharges at the solar arrays. One is electric charging phenomenon at a coverglass surface of the solar cell by interaction between the solar cell and the space plasma. The other one is electric field emphasis at a triple junction point that consists of the coverglass and interconnector in the space plasma. In this paper, the charging phenomena of the coverglass on the solar cell under Low Earth Orbit space plasma environment is discussed. So, the charging experiments are carried out using a sample that consists of Acrylic insulator and Aluminum conductor in simulated LEO plasma environment. In the experiments, distributions of electric charges are measured to time on the insulator surface of the sample. As a result, it is clarified that the electric charging of the insulator surface is based on positive ions in the space, and the charging depends on the strength of the electric field on its surface. Therefore, electric discharges occur when the potential difference between the object of the solar system and plasma space increases.", "subitem_description_type": "Other"}]}, "item_5_description_32":

内容記述 | In recent years, as the solar power satellite, the spacecraft is enlarged and requires much higher voltage. However, there are some technical problems as using high voltage in the solar power system. In the space environment, electric discharges occur on the solar cell arrays and the discharges cause damage to the arrays and the efficiency falls. Therefore, it is important to work out to these problems for developing the application in the space. There are two causes in the electric discharges at the solar arrays. One is electric charging phenomenon at a coverglass surface of the solar cell by interaction between the solar cell and the space plasma. The other one is electric field emphasis at a triple junction point that consists of the coverglass and interconnector in the space plasma. In this paper, the charging phenomena of the coverglass on the solar cell under Low Earth Orbit space plasma environment is discussed. So, the charging experiments are carried out using a sample that consists of Acrylic insulator and Aluminum conductor in simulated LEO plasma environment. In the experiments, distributions of electric charges are measured to time on the insulator surface of the sample. As a result, it is clarified that the electric charging of the insulator surface is based on positive ions in the space, and the charging depends on the strength of the electric field on its surface. Therefore, electric discharges occur when the potential difference between the object of the solar system and plasma space increases. | |||||
