NOVELTY - A converter comprises photosensitive layer(s) and collector electrodes. The photosensitive layer(s) achieves the generation of a photocurrent through the absorption of electromagnetic radiation. The collector electrodes are distinguished by the fact that it also contains metallic nanoparticles, by size of 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 the radiation.    USE - Converter for electromagnetic radiation used in production of solar photocells (claimed).    ADVANTAGE - The converter provides intensification of photocurrent, and enhancement of efficiency of converter. The converter is low cost as compared with silicon-based ones, permits its realization by modification of existing photocells in order to enhance their efficiency, and has efficiency 1.5-2 times greater than the efficiency of traditional photocells.    DETAILED DESCRIPTION - A converter comprises photosensitive layer(s) and collector electrodes. The photosensitive layer(s) achieves the generation of a photocurrent through the absorption of electromagnetic radiation. The collector electrodes are distinguished by the fact that it also contains metallic nanoparticles, by size of 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 the radiation. The nanoparticles are disposed on the front side of the converter that receives the incident electromagnetic radiation. The confining layer is a dielectric or semiconductor layer. The photosensitive layer(s) contains metallic nanoparticles.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the converter.
