Abstract: The invention relates to converters of the energy of electromagnetic radiation to electrical energy and may be used in the production of solar photocells. The converter according to the invention contains at least one photosensitive layer that achieves the generation of a photocurrent through the absorption of electromagnetic radiation, as well as collector electrodes. At the same time, the converter also contains metallic nanoparticles, the size of which is on the order of, or less than, the wavelength in the maximum of the spectrum of the incident radiation, that achieve the concentration of the incident radiation in the near-field around the nanoparticles and the generation of a photocurrent through the absorption of said radiation. Intensification of the photocurrent and enhancement of the efficiency of the converter are achieved as a result.
