Abstract: Complete mutual solubility in the (In$_2$S$_3$)$_x$(FeIn$_2$S$_4$)$_{1-x}$ system is established. The technology is developed, and single crystals of the continuous series of the (In$_2$S$_3$)$_x$(FeIn$_2$S$_4$)$_{1-x}$ solid solutions are grown for the first time. The linear dependence of the unit cell parameter of single crystals with a cubic spinel lattice on the solid solution composition is found. First, photosensitive Schottky barriers are fabricated, and then, based on studies of their photosensitivity, the character of band-to-band transition is discussed and the values of the band gap depending on the atomic composition are estimated. The possibility of using the obtained solid solutions as broadband photoconverters of optical radiation is revealed.
