CLAIMS

1. An integrated system for the cultivation of algae or plants and the production of electric energy, comprising:

- at least one Luminescent Solar Concentrator

(LSC) in which at least one photovoltaic cell (or solar cell) is positioned on at least one of its outer sides;

- at least one cultivation area.

2. The integrated system for the cultivation of algae or plants and the production of electric energy according to claim 1, wherein said luminescent solar concentrator (LSC) is interposed between said cultivation area and solar light.

3. The integrated system for the cultivation of algae or plants and the production of electric energy according to claim 2, wherein said luminescent solar concentrator (LSC) is interposed between said cultivation area and solar light so as to totally or partially cover said cultivation area.

4. The integrated system for the cultivation of algae or plants and the production of electric energy according to claim 1, wherein said luminescent solar concentrator (LSC) is an integral part of said cultivation area and solar light.

5. The integrated system for the cultivation of algae or plants and the production of electric energy according to any of the previous claims, wherein said cultivation area is selected from: open ponds (OP), photoreactors (FR), photobioreactors (FBR) or combinations thereof.

6. The integrated system for the cultivation of algae or plants and the production of electric energy according to any of the claims from 1 to 4, wherein said cultivation area is a greenhouse.

7. The integrated system for the cultivation of algae or plants and the production of electric energy according to claim 6, wherein said luminescent solar concentrator (LSC) forms at least partially or totally the roof or at least partially or totally the walls of said greenhouse.

8. The integrated system for the cultivation of algae or plants and the production of electric energy according to any of the previous claims, wherein said luminescent solar concentrator comprises at least one photoluminescent compound having an absorption range within the range of solar radiation, capable of activating photosynthesis ( Photosynthetically Active Radiations - PAR.s: 400 nm - 700 nm) and an emission range capable of activating the photovoltaic cell (or solar cell) . 9. The integrated system for the cultivation of algae or plants and the production of electric energy according to claim 8, wherein said photoluminescent compound is selected from: acene compounds; benzothiadiazole compounds; benzoheterodiazole compounds disubstituted with benzodithiophene groups; naphthoheterodiazole compounds disubstituted with benzodithiophene groups; naphthothiadiazole compounds disubstituted with thiophene groups; perylene compounds known under the trade-name of Lumogen® of Basf.

10. The integrated system for the cultivation of algae or plants and the production of electric energy according to any of the previous claims, wherein said luminescent solar concentrator (LSC) comprises a matrix made of transparent material selected from: transparent polymers such as polymethylmethacrylate (PMMA), polycarbonate (PC) polyisobutyl methacrylate, polyethyl methacrylate, polyallyl diglycol carbonate, polymethacrylimide, polycarbonate ether, styrene acrylonitrile, polystyrene, methyl-methacrylate styrene copolymers, polyether sulfone, polysulfone, cellulose triacetate, or mixtures thereof; transparent glass such as silica, quartz, alumina, titania, or mixtures thereof.

11. The integrated system for the cultivation of algae or plants and the production of electric energy according to any of the claims from 8 to 10, wherein said photoluminescent compound is present in said luminescent solar concentrator

(LSC) in an amount ranging from 0.1 g per surface unit to 5 g per surface unit, said surface unit referring to the surface of the matrix of transparent material expressed as m2.

12. An integrated process for the cultivation of algae and the production of electric energy comprising:

- cultivating at least one alga in the presence of an aqueous culture medium in a cultivation area comprising at least one luminescent solar concentrator (LSC) in which at least one photovoltaic cell (or solar cell) is positioned on at least one of its outer sides, obtaining an aqueous suspension of algal biomass and electric energy;

- recovering said algal biomass from said aqueous suspension of algal biomass;

- recovering said electric energy.

13. The integrated process for the cultivation of algae and the production of electric energy according to claim 12, wherein the electric energy recovered by means of said luminescent solar concentrator (LSC) is used in the above-mentioned process for the cultivation of algae, for example for the management of open ponds (OP), photoreactors (FR), photobioreactors (FBR), in particular for stirring the suspension of the algal biomass formed during growth, for the distribution of liquids and gas, for the functioning of the equipment for the collection, concentration and conversion of the microalgae into precursors of biofuel, either chemically or thermo-chemically.
