Provided is an apparatus for manufacturing a composite material consisting of a flexible substrate and a multilayer nanostructured PV-active film supported by the substrate. The apparatus comprises a sealable chamber, the cylindrical inner wall of which is used as a support for a flexible substrate. The chamber contains a rotating crucible having a recess in its center and flat margins. The apparatus is provided with a power laser capable of generating an annular beam focused on the aforementioned flat surface. In operation, a nanoparticle-containing colloidal solution is supplied to the crucible. During rotation, the solution moves to the flat margins where it forms a thin layer that is evaporated by means of the annular laser beam. As the solution evaporates, the nanoparticles, which remain on the surface, fly out by inertia from the edges of the crucible to the flexible substrate. The deposition process can be controlled so that the deposited layers form a PV-active film.
