Reliability and structural properties of selective TiN{sub x}O{sub y}-Cu tandem absorbers for solar applications at high temperatures were investigated. A tempering process which improves thermal emittance of the coatings was observed. Degradation is monitored by directional total thermal emittance. Four steps of degradation have been separated and confirmed by XRD, EDAX, REM and optical spectroscopy. Coatings show crystalline phases and transitions to amorphous due to degradation and tempering. They are susceptible to oxidation and to reactions with the substrate.
