1. A device for the storage and transfer of thermal energy of solar origin, comprising:
a containment casing, having an irradiation opening configured to allow the entrance of an incident solar radiation in an irradiation region defined within said casing;
a bed of fluidizable particles received within said casing;
a reflecting and/or re-radiating surface arranged within said irradiation region and configured to reflect the solar radiation entering through said irradiation opening directly on a freeboard of said bed of particles or on another reflecting and/or re-radiating surface of said irradiation region; and
a plurality of reflecting surfaces arranged within said irradiation region and each reflecting surface configured to reflect the solar radiation entering through said irradiation opening, the overall configuration being such that the inletting radiation hits the freeboard of the bed of particles-downwards of multiple reflections on said reflecting surfaces.
