The object of investigation is new optical materials based on the films of polymethyl methacrylate (PMMA) containing silver nanoclusters deposited on the surface silicon. The effect of a giant enhancement of light in the metal-polymer composite coatings revealed experimentally that holds great promise for the use of metal-polymer composite coatings to improve the efficiency of silicon solar cells. Optical properties of nanoobjects such as metal nanoparticles, nanospheres, nanoclusters, nanoaggregates, ultra-thin nanofilms and dimers on solid surfaces can be used as the basis for the development of unique optical methods of investigation and creation of unique optical devices. When considering such objects a field of optical emission should be considered as quantum field and take into account the near-field effect. We offer a method for computing the microscopic polarizing fields for nanostructures and nanocoatings with metal nanoparticles and nanoclusters in the field of optical photons. We try to create an effective method of computation of optical characteristics of composite films activated by metal nano-particles, nanoclusters and nanoagregates, which are located in an external field of coherent or incoherent optical emission. Optical properties of monolayer of metal nanoparticles are considered on the silicon substrate and the metal-polymer com-posite film with introducing the system of metallic nanoparticles, nanoclusters and nanoaggregats. We show that the radiation model of metal nanoclusters allows computing the effective parameters in the form of spheres and bispheres. We offer a method of computing lattice sums of the interacting metal nanoclusters, disposed on the surface of silicon substrate, allowing explanation of the effect of increasing of optical transmission in absorbing media. We show that in the system of interacting metal nanoparticles, nanoclusters, nanoaggregates in the form of three-dimensional «chamomiles», composed of densely packed spherical particles, by changing the structure factor can control the enhancement of light in metal-polymer nanocomposite film on the silicon substrate. We show that metal-polymer nanocomposite film actuated spherical nanoparticles can ensure the ideal optical transmission when amplitude transmitted light wave is equal to the amplitude of external wave at different angles of incidence, regardless of the optical properties of the substrate medium. In this case the amplitude of reflected wave applies to zero in the wide range of optical wavelengths. We show that effect of an ideal optical enlightenment exists when efficient complex index of refraction of a metal-polymer composite nanocomposite film tends to zero.
