The Cu 2 S and SnS 2 layers have been prepared by the chemical bath deposition method. The results of SEM and EDX analyses confirm a high stoichiometry of the synthesized semiconductor thin films. The optical properties of the Cu 2 S and SnS 2 layers have been studied, and the optical band gap values have been determined.

More than 300 scholars and experts from the Spanish-speaking world took part in the IX International Congress of the Spanish Language held in Cádiz from 27 to 30 March 2023. Special attention was paid to the indigenous languages of Latin America and the Caribbean.
