As a result of work are received p-n heterojunctions in thin-film execution, described by high values of differential resistance. Results of researches show, that film p-n the structures received by a method of discrete thermal evaporation in a uniform work cycle, are suitable for use in low-voltage devices. The effect of conditions of precipitation on clarifying properties SiOх of surface slicks for thermophotovoltaic elements on a basis Bi2Se3 and Bi2Te3 is probed. The comparison with values of a current density of short-circuit raw of thermophotovoltaic elements is conducted. The augmentation of a current density with body height of concentration of oxygen in a mixed gas is exhibited during precipitation of a film that is explained by smaller absorption of a light in a film. For the maximal augmentation of a current of short-circuit of thermophotovoltaic elements the optimum thickness of optical stratums is defined.
