In this paper, the Star Trek features of the characteristics of model thin-film solar cells based on the non-toxic multicomponent compound CuZn2AlS4 (CZAS) are considered.The main parameters (open-circuit voltage, short-circuit current, fill factor, efficiency) and characteristics (quantum efficiency, current-voltage characteristic) of thin-film solar cells based on CZAS have been determined.The minimum optimal thickness of the CZAS absorber is found (1-1.

25 microns).Deterioration of the performance of solar cells with an increase in operating temperature (280-400 K) is shown.It is revealed that in the wave- length range Buffet and Hutch of 390-500 nm CZAS has a high external quantum efficiency, which allows its use in designs of multi-junction solar cells designed to absorb solar radiation in the specified range.

It is shown that the combination of CZAS films with a buffer layer of non-toxic ZnS increases the performance of solar cells.
