Abstract

See full text

The invention relates to a solar selective absorbing coating and a preparation method thereof. The solar selective absorbing coating comprises a substrate, an infrared reflective layer, an absorbing layer and an antireflective layer in sequence from bottom to surface. The absorbing layer consists of a first sublayer, a second sublayer and a third sublayer. The first sublayer and the second sublayer contain metal nitride, and the third sublayer is metal oxynitride. The first sublayer is in contact with the infrared reflective layer, and the third sublayer is in contact with the antireflective layer. The preparation method comprises: depositing an infrared reflective layer on a substrate; depositing an absorbing layer on the infrared reflective layer; and depositing the antireflective layer on the absorbing layer. According to the metal nitride (oxynitride) solar selective absorbing coating, the working temperature of the metal nitride (oxynitride) solar selective absorbing coating is increased, the preparation is simple, and the coating is suitable for large-scale production.
