Created single-stage model of silicon solar cell using PC1D v.5.9 program, designed to simulate the photovoltaic devices. In the process of simulation change the level of doping and thickness of the n + type layer of the front, as well as applied texturing the front surface. The influence of the doping level and the thickness of the n + type layer in the photovoltaic solar cell characteristics. It was determined that with the increase of the doping level and the thickness of the front n + -layer a decrease in the efficiency of solar cells. It was found that the use of texturing the front surface leads to an increase in efficiency and is associated with reduced reflection losses and an increase in the photocurrent.

Currently, laser annealing are widely used to create a polycrystalline silicon film, which is promising for use in thin film solar cell, and transistors, liquid crystal displays and sensors due to recrystallization of amorphous and nanocrystalline silicon films. The study of morphology and surface conductivity of single-crystal silicon film on a glass substrate by laser annealing power. Laser annealing is carried Nd: YAG laser with a wavelength of 532 nm, speed of movement of the stage with a specimen of 5 mm/s and a laser power ranging from 34 to 86 watts. The laser beam was focused on the sample in the form of a narrow line width of 10 microns and 60 mm in length. The dependence of the size of the nanocrystals and the conductivity of silicon films on the power of the laser annealing radiation. It is shown that the power of the laser radiation in the range of 60 to 70 W is optimal for the best electrical parameters silicon film for the purpose of its use in high-performance thin-film solar cells.

A numerical model of the laser annealing TiO2 film on the TCO / glass substrate with radiation of a wavelength of 1064nm (Nd: YAG laser) to the crystallization and its use in solar cells perovskite. The modeling used a numerical finite difference method for solving a system of one-dimensional unsteady heat conduction differential equations. As a result, laser annealing temperature distribution obtained in the process of modeling the structure of TiO2 / TCO / glass substrate by varying the laser power. It is shown that a high laser power (30-100 watts) is enough for an effective transition organometallic precursor of TiO2 in the crystalline phase of anatase TiO2 (transition temperature of 400-600 °C) for a short period of time (60 sec.) due to the direct absorption of photons laser radiation. It is found that for experimental studies should be used laser power of 30-70 watts, since a higher power (e.g., 100 W) raises the temperature of the substrate above its melting point (for example, for glass 650 ° C).

Readiness of contemporary youth for formation of stable marriage-family relations is a necessary factor forming stable functioning of a society and also a determining factor of social and national security, which is very essential nowadays in the conditions of non-stability, various challenges and risks. Compatibility/non-compatibility of ideal behavior models of the contemporary youth with the real models in the chosen aspect represents itself as an important criterion of determination of readiness/not readiness of youth for family formation. Today there have been distinguished the factors influencing the formation of an ideal partner of other gender, these are family (parents, relatives), referent groups, first experience of communication with other gender, mass media, etc.

The problems of drinking water supply of Russian population in rural areas, where the level of life support is lower than in urban areas are not just escalated but become depopulation factor in some regions. While developing and recommending any water treatment technology first of all it is necessary to be guided by the chemical composition of source water. In many rural areas groundwater has become the only source of drinking water, because the level of surface water contamination and hydrometric characteristics make them unsuitable for use. The data for the survey of physical and chemical composition of groundwater and groundwater from wells and public wells used in the drinking water supply of Kuibyshev district in Rostov region are delivered. The analysis showed that Kuibyshev region belongs to the areas of virtual absence in fresh groundwater resources, where groundwater with increased salinity and high content of sulfates and hardness are prevailed .The ecological assessment of using this water desalination method as reverse osmosis was carried out in this study. In areas with no centralized sewerage and sewage treatment facilities, the Kuibyshev region belongs to, using of this method is inappropriate.
