Systems and methods disclosed herein are directed towards the fabrication of a solar absorber comprising an IR reflector layer deposited on a substrate; a first cermet layer deposited in contact with the IR reflector layer; a second cermet layer deposited in contact with the first cermet layer; a first anti-reflection coating layer deposited in contact with the second cermet layer; a second anti-reflection coating layer deposited in contact with the first anti-reflection coating layer. A sputtering process may be used to deposit some or all of the layers, and the YSZ layers in each cermet layer may be deposited with a tuned partial oxygen pressure in order to form a layer that is oxygen-deficient.
