The optical properties of perovskites of the CsSn[Br1–xIx]3 system in the spectral frequency range of 3–10 THz were studied by quantum-chemical calculations in the framework of DFT using the Wien2K package, and the frequency dependences of the refractive index, photoconductivity, and absorption coefficient of these nanocrystals were estimated. It has been established that in the indicated frequency range with an increase in the iodine content, the absorbing properties of the CsSn[Br1–xIx]3 (x=0.25, 0.50, 0.75, 1.00) system increase linearly.
