Abstract
The study of renewable energy sources is currently an urgent problem. Such materials are produced by constructing phase diagrams or by cation–anionic substitution of an existing material. From this point of view, the formation of a solid solution (CdSe)1–x(As2S3)x can be due to anionic substitution, which is capable of creating functional properties. In this regard, differential thermal analysis (DTA), X-ray diffraction (XRD), microstructural analysis (MSA), as well as measurements of microhardness and density were performed on solid solutions (CdSe)1–x(As2S3)x. The nature of the chemical interaction of CdSe with As2S3 was studied and it was established that the introduction of As2S3 into the composition of CdSe leads to the formation of solid solutions. Moreover, it has been found that solid solutions are formed up to 3 mol% concentration of As2S3. The temperature dependence of the electrical conductivity and thermo-EMF of (CdSe)1–x(As2S3)x (x = 0.01; 0.02; 0.03) solid solutions has been studied. It has been established that the obtained alloys of the solid solution (CdSe)1–x(As2S3)x (x = (x = 0.01; 0.02; 0.03) are semiconductors of medium resistance. When introducing high-resistance samples of 1; 2 and 3 mol. % As2S3 into the composition of CdSe, the specific resistance of the alloys increases depending on the composition, and the conductivity decreases accordingly. For alloys of solid solutions (CdSe)1–x(As2S3)x, in the composition of 0.3; 0.6; 0.8 and 1.0 mol % As2S3, the spectral distribution of the photocurrent was studied. Samples containing 0.3; 0.6; 0.8 and 1.0 mol% As2S3 are photosensitive materials capable of operating in the wavelength range of 0.4–1.1 μm.
