Production of a concentrating sub-module using photovoltaic assembly methods

A concentrating photovoltaic solar sub-module equipped with a reflective face having a concave predefined geometric shape, comprising:

• a structural element equipped with a reflective first face and a second face, opposite the first face, the structural element comprising a core flanked by two skins, one of the two skins making direct contact with a reflective layer forming the reflective first face of the structural element and the reflective face of the sub-module, the second skin forming the second face of the structural element;
• a photovoltaic receiver, placed in direct contact with the second face of the structural element;
• a layer made of transparent encapsulating material, covering the photovoltaic receiver;
• and
• a transparent protective layer, forming a second face of the sub-module, which face is opposite the reflective face, said layer covering the layer made of transparent encapsulating material.
