SYSTEMS OF PHOTOELECTRIC CONVERTERS OF SOLAR RADIATION Russian patent published in 2011 - IPC H01L31/04 

FIELD: physics.

SUBSTANCE: system has an optical system which splits solar spectrum radiation into four light fluxes with different spectral ranges and four photoelectric converters (27)-(30) with a single p-n junction. The photoelectric converters (27)-(30) lie next to each other and are electrically connected to each other. The first photoelectric converter (27) is made from semiconductor material with E_g=1.8-2.3 eV; the second photoelectric converter (28) is made from semiconductor material with E_g=1.3-1.5 eV; the third photoelectric converter (29) is made from semiconductor material with E_g=0.9-1.1 eV and the fourth photoelectric converter (30) is made from semiconductor material with E_g=0.6-1.75 eV.

EFFECT: high overall efficiency of converting solar radiation.
