Microstructural, optical properties and thermal stability of MgO/Zr/MgO multilayered selective solar absorber coatings

•MgO/Zr/MgO selective solar absorber was fabricated using e-beam evaporator.•Solar absorptance ∼0.92 and low thermal emittance ∼0.09 was achieved.•MgO/Zr/MgO solar absorber was thermally stable in vacuum up to 400°C for 2h.•At 500°C, oxidation of the Zr base layer and diffusion towards the surface w...
