| Summary: | The scientific direction of the synthesis of CdS and CdSe thin films by the method of chemical surface deposition (CSD) using the aqueous solutions of cadmium-containing salts: chloride, nitrate, sulphate, acetate and iodide has been developed. A mathematical model of the CSD process of CdS and CdSe thin films was developed to improve the efficiency of experiments and reduce costs. The model makes it possible to determine the concentration of reagents, the duration, and the CSD temperature, which are necessary to obtain films of a specified thickness. The optimization of chemical deposition parameters of filmtype semiconductor materials has been carried out. Based on the mathematical model, the optimal synthesis conditions were the following: the concentration of cadmium-source salt – 0.01 mol/L, chalcogenizer – 1.0 mol/L or 0.1 mol/L in the case of thiourea or sodium selenosulphate, respectively; the temperature: 70 °C and the duration of 3 min. The mathematical dependence of the experimental studies results of the metal ions content in thin-film solar cells for the effective direct conversion of solar radiation into electrical energy was proposed taking errors into account. |
