Abstract: A technology of growing single crystals of (In$_2$S$_3$)$_x$(MnIn$_2$S$_4$)$_{1-x}$ solid solutions that provides control over their atomic composition in the entire concentration range 0 $\le x\le$ 1 is developed. It is shown that, in the range $x$ = 0 – 1, the single crystals have the cubic spinel structure and the unit cell parameter $a$ follows the linear dependence on $x$. The exponential character of the temperature dependence of resistivity of solid solutions, on which the first photosensitive Cu/(In$_2$S$_3$)$_x$(MnIn$_2$S$_4$)$_{1-x}$ structures are obtained, is revealed. The first photosensitivity spectra of these structures are obtained, and, based on these spectra, dependences of energy of the direct and indirect band-to-band transitions on the composition $x$ are determined. The possibility of applying these structures in broad-band photoconverters of optical radiation is concluded.
