The invention relates to electromagnetic emission converters. In the first variant, the inventive converter comprises at least one collecting area of a first conductivity type, at least one collecting area of a second conductivity type and first and second current-collecting conducting electrodes. The N>1 first conductivity type areas, each of which is disposed at a distance of F<2f to the other areas of the same conductivity type, where f is a quantity commensurable with or equal to the diffusion length of nonequilibrum minority charge carriers, are made on the first, incident electromagnetic emission reception side of a second conductivity type substrate. In the second variant, the inventive converter comprises at least one collecting area of a first conductivity type, at least one collecting area of a second conductivity type and first and second current-collecting conducting electrodes. The first electrode is connected to said first conductivity type area disposed on the first incident electromagnetic emission reception side of the second conductivity type substrate and comprises T>1 segments, the distance between two such segments is less than 2f, where f is a quantity commensurable with or equal to the diffusion length of nonequilibrum minority charge carriers, the above-mentioned segments of the first electrode are combined into a current node in the internal circuit of the converter by means of at least one current bus. Said invention makes it possible to increase the energy conversion efficiency (increased performance) in comparison with solutions known from the prior art. |
