The invention concerns a multilayer material comprising at least: a support having a reflectance R higher than 80% for radiations of wavelengths higher than 5 μm, a selective layer comprising a combination of Vanadium oxides VO2 and VO2O2n+/−1, with n>1, said selective layer having an absorbance higher than 75% for radiations of wavelengths comprised between 0.4 and 2.5 μm, regardless of the temperature T, and having, for radiations of wavelengths comprised between 6 and 10 μm, a transmittance Tr such that: Tr>85% for T Tc. Application to the production of thermal solar panels having a low stagnation temperature and high performance.
