This paper presents the surface analysis of a black copper selective coating using AES and XPS techniques. This study indicates that the textured black copper selective coating is a multiphase system. These surfaces are stable up to 250°C in air and under vacuum conditions. Subsequent annealing of these surfaces to temperatures > 370°C shows significant changes. The external environment exposed surface has indicated no significant change.
