TL;DR: In this article, optical and Auger analysis have been performed to characterize the oxidized copper surfaces, which have been exposed to accelerated and natural ageing, and the analyses have shown that the absorption can be increased if the copper surface is mechanically brushed prior to oxidation and that a post-treatment which gives a protective layer on top of the copper oxide is essential for the durability.

Journal ArticleDOI
