Ground-based investigation of atomic oxygen effects on naked Ag and Ag with protective organic coating

Protective behavior of organic coatinge of alkyd,epoxy,urethane and siloxance applied to silver solar cell interconnects and erosion of Ag were investigated by exposure experiments to ground simulation atomic oxygen(AO).Evaluations of their protective properties were made through assessing their mass cfhange characteristics,chemical and physical changes to Ao attack.The specimens,after exposure were analyzed with SEM/EDAX and XPS.The results indicated that the silver is heavily etched.some coatings such as epoxy,alkd,urethane are seriously degraded or removed as volatile oxides and morphology of coatings changes.It is evident that siloxane coatings have excellent properties for anti-AO attack.The erosion product consists of silicon dioxide layer of compact texture and is left on the surface to provide adequate protection fro further attack by the energetic AO.
