Increasing the operating temperature of parabolic trough solar fields from 400 C to >450 C will increase their efficiency and reduce the cost of electricity. Current coatings do not have the stability and performance necessary to move to higher operating temperatures. The objective is to develop new, more efficient selective coatings with both high solar absoprtance ({alpha} > 0.96) and low thermal emittance ({var_epsilon} < 0.07) that are thermally stable above 450 C, ideally in air, with improved durability and manufacturability, and reduced cost.
