The invention concerns a multilayer coating with high absorption of solar energy and with low thermal emissivity that comprises a first layer of molybdenum; a second layer essentially made up of TiO 2 and niobium metal; and a third layer of SiO 2 . The invention moreover concerns a relative cermet composite essentially made up of TiO 2 and niobium metal in which the concentration of niobium in the TiO 2 corresponds to 27 - 34 at.%, preferably to 29.6 - 32.0 at.%, more preferably to 30.2 - 31.4 at.%, even more preferably to around 30.8 at.%. Furthermore, processes for producing the coating and the cermet composite, laminar or tubular materials coated with the coating and a use of the cermet composite are proposed.

The invention is a volumetric receiver (100, 200) configured to absorb the radiation (R) emitted by a heat source (S) and incident on an exposed face (102, 202) of the same volumetric receiver (100, 200) and to transfer the thermal energy induced by said absorption to a surrounding heat transfer fluid (F). This volumetric receiver (100, 200) comprises a plurality of hollow cells (1 ) whose longitudinal axes are substantially orthogonal with respect to the exposed face (102, 202), wherein the hollow cells (1 ) are adjacent and stably connected to one another in such a way as to define at least one level (104; 204a, 204b, 204c) substantially parallel to the exposed face (102, 202), each one of the hollow cells (1 ) defining a channel open at both its ends opposite each other according to said longitudinal axis and each one of the hollow cells (1 ) being also provided with an opening (3) made on its lateral surface (2).
