The effect to various factors such as temperature, concentration of components in the electrolyte, current density on the composition of thin electrodeposited semiconductive Sb-Se films were viewed in the work. Results obtained indicate that the stibium content in the deposited compounds increases as temperature and concentration of SbOCl rise. As the current density, H2SeO3 and C4H6O6 concentration rises, the stibium content in the films obtained goes dpwn respectively. It revealed that black, uniform, crystalline and lustrous coatings of Sb2Se3 compound are generated in temperature interval 298-318К, current density 20-60 мА/cm 2 out of electrolyte 0,01-0,09 М SbOCl,0,01-0,09 МH2SeO3, and compounds of 0.001-0.007 М tartaric acid.

“…There are different methods for obtaining thin films of metal-chalcogenides, including chemical vapor deposition, pyrolytic decomposition, thermal evaporation, hydrothermal synthesis, inert gas condensation and electrochemical method [15][16][17][18][19][20][21][22][23][24][25]. A highly crystalline Sb 2 Se 3 sample was obtained by thermal evaporation and chemical precipitation method in a nitrogen atmosphere [9,26].…”

The present contribution is devoted to the electrochemical deposition of Sb2Se3 thin films from tartrate electrolyte. The study was conducted by potentiodynamic, potentiostatic and galvanostatic methods carried out under different conditions at Pt, Cu and Ni electrodes. The kinetics and mechanism of the electroreduction of antimony and selenite ions in the tartaric acid were studied separately for the electrochemical deposition. Comparison of the obtained polarization curves showed that co-deposition occurs between electroreduction potentials of antimony and selenium, indicating depolarization electrode effect for antimony ions. The influence of electrolyte composition, pH, current density, temperature, etc. has been studied. On the basis of cyclic polarization, X-ray phase and SEM-EDX analyses, it is found that Sb-Se thin films are deposited on Pt and Ni electrodes, but not on Cu electrode. Black, uniform, crystalline and shiny films of the stoichiometric composition of Sb2Se3 compound are deposited on Pt and Ni electrodes within the 338-348 K temperature interval, pH 1.85, current density of 2.5-3.0 A/dm2, and annealing temperature of 703 K. Experiments were carried out using the optimal electrolyte composition containing 0.05 M SbOCl + 0.05 M H2SeO3 + 0.007 M C4H6O6.

“…As known, semiconductors are one of the most important materials that differ from each other by their great manifold of the physical and electrical properties, also of the chemical composition. [1][2][3][4] The need for the chalcogenide semiconductor films increases with the development of the application of the new generation of solar cells. 5 Today, the using of ecologically waste free solar energy is very actual connecting with the decreasing of the natural resources of the energy.…”

The electrochemical reduction of molybdate ions in tartaric electrolyte has been investigated in this work. Kinetics and mechanism of the electrochemical process have been studied by cyclic and linear voltammetric polarization methods. The effect of the temperature, the rate of potential-scanning and the concentration of the molybdate ions on the electrochemical process has been also studied. By estimating the effective activation energy, it was revealed that the electroreduction process is accompanied by mixing kinetics control.
