  • the pockets 12 penetrate the base body 11 in their entirety. It can thereby be achieved that the photovoltaic cells 5 or at least the lower embedding element 33 are accessible from the underside 8 of the photovoltaic module 3. As a result, improved cooling of the photovoltaic cells 5 can be achieved since water can slosh through the pockets 12 to the underside of the photovoltaic modules 3.
  • the pockets 12 do not completely penetrate the base body 11, but that a thin covering layer is formed, by means of which it is ensured that the photovoltaic cells 5 do not come into contact with water sloshing through the pockets 12 ,
  • the photovoltaic cells 5 can thus be enclosed in a watertight manner by the base body 11 and by the glass cover 35.
  • FIG. 10 shows a further exemplary embodiment of a photovoltaic module 3, again using the same reference numerals or component designations for the same parts as in the preceding FIGS. 1 to 9.
  • FIG. 10 shows a further exemplary embodiment of a photovoltaic module 3, again using the same reference numerals or component designations for the same parts as in the preceding FIGS. 1 to 9.
  • reference is made to the detailed description in the preceding figures 1 to 9 or reference.
  • the photovoltaic module 3 may be formed as a planar body or that at least the surface 27 of the photovoltaic cells 5 may be formed as a flat surface.
  • the lower embedding element 33 can be omitted.
