Abstract Molybdenum black solar selective coatings have been prepared by a simple chemical conversion method on chemically etched zinc substrates. These coatings have been characterized using X-ray diffraction, electron diffraction, XPS and VIS-IR reflectance spectroscopy. Maximum solar absorptance obtained from these coatings was about 0.87 with an emittance of 0.13–0.17. Selectivity of the coatings, mainly attributed to the coating surface morphology, was studied by SEM. Structural studies show that the coating consists of a non-stoichiometric oxide of Mo, namely Mo4O11. XPS depth profiling studies show that the oxidation state of Mo reduces from +5 to +4 after argon ion bombardment.
