Abstract: The work is devoted to investigation of thermal properties of solar cells based on GaAs / AlGaAs / GaP heterostructures with a total thickness of a highly absorbing GaAs layer not exceeding the sum of the diffusion length of minority carriers and a two-sided contact grid. It is shown that on the basis of such heterostructures, it is possible to create solar cells operating in the regime of natural convective heat transfer up to 100 times concentration of the solar flux.

Keywords: heterostructure, solid solution, width of the forbidden band, narrow-band semiconductor thermal conductivity coefficient, temperature coefficient.
