METAMORPHIC PHOTOVOLTAIC CONVERTER Russian patent published in 2017 - IPC H01L31/725 B82B1/00

Abstract RU 2611569 C1

FIELD: power industry.

SUBSTANCE: invention relates to the semiconductor electronics and can be used to produce solar cells. Metamorphic phototransformator includes a substrate (1) of GaAs, metamorphic buffer layer (2) and at least one photoactive p-n-junction (3), made of InGaAs and comprising a base layer (4) and the emitter layer (5), a layer (6) of the wide windows of In(Al_xGa_1-x)As, where x=0.2-0.5, and a contact sublayer (7) of InGaAs.

EFFECT: invention has increased the value of the photocurrent and the efficiency.
