Patent ID: 8143149

Claim:
A method of forming a flexible nanostructured material for a photovoltaic panel comprising: a. providing a flexible substrate; b. providing a liquid medium that contains nanoparticles selected from a group having different sizes and different types of material; c. providing a rotating body that has a surface; d. forming the flexible substrate into a substantially cylindrical body that has a longitudinal axis and surrounds the rotating body so that a space is provided between the rotating body and the flexible substrate; e. filling said space with a gaseous medium; f. placing the liquid medium onto said surface; g. providing an energy source capable of irradiating said surface and having energy sufficient for evaporating the liquid medium; and h. rotating the rotating body to impart centrifugal force to the liquid medium that contains nanoparticles and simultaneously evaporating the liquid medium by irradiating thereof with said energy source, thus releasing the nanoparticles from the liquid medium for their free flight through the gaseous medium toward the flexible substrate, whereby the particles of different sizes are deposited onto the flexible substrate in a predetermined sequence that corresponds to the magnitude of resistance experienced by the nanoparticles during their free flight so that said flexible nanostructured material is formed as a multilayer nanostructured film in which nanoparticles of larger size and greater density are deposited onto the flexible substrate and are located under the nanoparticles of smaller size and smaller density.
