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 coverglasses with coatings after electron irradiation. We found that the surface potential on coverglasses becomes positive within a few hours after irradiation. Comparing the surface potential histories of coated coverglass and silica glass revealed that the positive potential of coverglass 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 with lower secondary emission coefficient., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0061891025, レポート番号: JAXA-SP-12-017}, pages = {157--161}, publisher = {宇宙航空研究開発機構(JAXA), Japan Aerospace Exploration Agency (JAXA)}, title = {宇宙機用太陽電池カバーガラスのコーティング剤が帯電に与える影響}, volume = {JAXA-SP-12-017}, year = {2013} }
