THE MULTISTAGE CONVERTERS Russian patent published in 2012 - IPC H01L27/142 B82B1/00 

FIELD: optic and electric equipment.

SUBSTANCE: innovation relates to the devices of conversion of the optical energy into the electric one and can be applied both in concentrator photoelectric modular devices and cosmic solar batteries; the essence of the innovation is as follows: the multistage photoconverter contains the semiconductor body and includes at least two semicondacting p-n junctions comprising the emitting layer of at least one type of conductivity closely located in the photosensitive surface and the basic layer of the other type of conductivity, at that at least one р-n junction located under the first р-n junction has the emitting layer with the width of the band gap exceeding the width of the band gap of the basic layer located upper of the neighboring р-n junction.

EFFECT: creation of multistage photoconverters having the advanced coefficient of efficiency due to reduction of the recombination losses in the emitting layers and on the boundary surfaces of heterojunctions.
