Abstract: Studied photovoltaic processes in $\mathrm{GaAs/AlGaAs}$ heterostructure solar cell with a spectral sensitivity in the range of $450\leq\lambda\leq850$ nm under holographic concentrator illumination. It is shown that with increasing of concentration of the solar flux to 10krat with a linear increase in short-circuit current and open circuit voltage efficiency reaches its maximum value.

Keywords: solar sell, semi conduction, gallium arsenide, spektrowave diapazon, short circuit current, open circuit voltage, hologhraphic concentrator.
