  • the encapsulation layers 223 comprise, for example, an electrically insulating plastic.
  • the separator layer 221 comprises, for example, a porous plastic.
  • the electrolyte includes, for example, an organic electrolyte solution.
  • Figure 7 shows a schematic sectional illustration perpendicular to the light module level LE of a photovoltaic layer 280 of a light module 200 according to the invention, comprising a plurality of material layers aligned along the light module level LE with different material compositions.
  • the photovoltaic layer 280 is designed, for example, as a thin-film solar cell, comprising, for example, microcrystalline silicon ( ⁇ c-Si: H) as the photoactive material.
  • ⁇ c-Si: H microcrystalline silicon
  • the photovoltaic layer 280 comprises, for example, perpendicular to the light module plane LE one above the other, a translucent front electrode layer 281 and then a photoactive layer 282 with the photoactive material and then a back electrode layer 283.
  • the termination of the photovoltaic layer 280 perpendicular to the light module level LE forms, for example, in each case an electrically insulating encapsulation layer 223, for example made of a plastic.
  • Figure 8 shows schematically a holding device 100 according to the invention for holding folders 300 according to the invention.
  • the holding device 100 shown comprises at least one inductive transmission device for inductive charging of the energy storage layer of the at least one light module of the folders 300.
  • each receiving shaft 140 being designed to hold a folder 300 in such a way that at least one induction coil 231 of the at least one induction layer 230 of the at least one light module 200 of the respective folder 300 is arranged coaxially to at least one induction coil 131 of the at least one transmission device 130.
  • the at least one induction coil 131 is arranged, for example, under a support surface 141 of a receiving shaft 140 for supporting the folder 300.
  • the support surface 141 is preferably inclined relative to a vertical plane and relative to a horizontal plane.
  • a plurality of receiving shafts 140 could also be arranged vertically one above the other with horizontal support surfaces 141 in the holding device 100, as in the case of a shelf system.
  • the induction coils 231 of the folders 300 can be arranged coaxially to the induction coils 131 of the holding device 100 independently of an orientation of the folders 300 relative to the holding device 100, the induction coils 231 of the folders 300 are preferably arranged centrally in the respective folders 300.
