Spacecrafts are charged under plasma environment and radiation environment in space, and it may lead failures and anomalies of spacecrafts when discharge on the spacecraft surface occurs. One of the most important surface materials is cover glass for solar-cells which is a source of an electrical power. The purpose of this paper is to investigate surface-potential characteristics of cover glasses with coatings after electron irradiation. We found that the surface potential on cover glasses becomes positive within a few hours after irradiation. Comparing the surface potential histories of coated cover glass and silica glass revealed that the positive potential of cover glass is due to ionization of metallic atoms in surface coating material. The positive potential is relaxed over several days which will increase a risk of discharge. We conclude it is necessary to select coating materials difficult to ionization by charged particles.
