A process for producing a multilayered composite composition which has a discrete layer or layers of nanoparticles within a layer of a polymer, is described. The nanoparticles are precipitated in a liquid polymer, preferably, by heating or solubilization of the polymer. The composite compositions are useful for use in photovoltaic devices as well as for in settings where multiple layers are important such as for low gas or liquid permeability films.
