CONVERTER OF ELECTROMAGNET RADIATION (VERSIONS) Russian patent published in 2009 - IPC H01L31/04 

FIELD: electric engineering.

SUBSTANCE: invention is related to converters of electromagnet radiation. According to the first version converter comprises at least one collecting area with conductivity of the first type and at least one collecting area with conductivity of the second type, and also current-collecting conducting electrodes connected to mentioned areas. Besides on the first side of substrate that perceivers dropping electromagnet radiation with conductivity of the second type there are N>1 areas arranged with conductivity of the first type, every of which is located relative to the other areas with the same conductivity at the distance of F<2f, where f - value comparable to diffusion length or equal to diffusion length of unbalanced minority carriers of charge. According to the second version converter comprises single collecting area with conductivity of the first type and at least one collecting area with conductivity of the second type, and also the first and second current-collecting conducting electrodes connected to mentioned areas. At the same time the first electrode is connected to specified area with conductivity of the first type, located on the first side of substrate that perceives dropping electromagnet radiation with conductivity of the second type, moreover, the first electrode comprises T>1 sections and distance between every two such sections is less than 2f, where f - value comparable to diffusion length or equal to diffusion length of unbalanced minority carriers of charge, and moreover specified sections of the first electrode are combined in internal circuit of converter into current unit via at least one current-conducting bus bar.

EFFECT: invention provides for higher efficiency of energy conversion (higher efficiency factor).
