Work is devoted to experimental evaluation of resistance spread, the main part of the serial resistance planar photoconverters, which has a significant impact on the efficiency of the solar cell. In the process of experimental works considered several approaches to the solution of the task. The main approaches are based on the research portion of the silicon structures, carved from the finished serial converter, which allows you to measure the resistance of the doped layer in the longitudinal direction.

The paper presents the methodology and the results of calculation of the energy parameters of the flat solar collector (FSC), in particular, hourly and daily average efficiency (efficiencies)  of FSC, working under the climatic conditions of the Absheron Peninsula, in particular Baku, located in the northern latitude 40°24′. Calculations were carried out in example 15 January 2014 for experimental FSC, which passed for several years full-scale tests in geliopoligone laboratory of “Transformation of renewable energy” of the Institute of Radiation Problems of Azerbaijan National Academy of Sciences. It has been determined that for the specified day, average efficiency of FSC is η avday  = 22.1%. 

In this paper some new photovoltaic modules, including trapeziform with mounted photoсells receiver and half-parabolocylindrical concentrator, to ensure efficient conversion of solar energy into heat and  electricity, was investigation. The mathematical modeling to creation a computational algorithm design thermo-photoelectrical module the specified power parameters using laws of geometrical optics, as well as heat and mass transfer. When using such modules, in which basis is half-parabolocylindrical concentrator and photocell system with coolant flow can create cogeneration plants to generate electricity and heat. Developed by this method of model samples are examined for appropriate stands and tested in field conditions. The heat and electrical parameters become defined according to the calculation results to within 10%.  The solar module with half-parabolocylindrical concentrator, trapeziform concentrated radiation receiver with mounted photoсells and coolant flow system delivers maximum output 254 W at 43 °C, 219 W at 74 °С and 236 W at 58 °С. Concentrating solar radiation to 50, uniformly of  insolation 0.25.  The solar module with half-parabolocylindrical concentrator, trapeziform concentrated radiation receiver with mounted matrix high-photovoltaic сells and coolant flow system was investigated also. Coefficients of occupy volt-amperes characteristic was m = 0,728 and 0,660 for concentrate and non concentrate solar stream correspondingly.

The article presents data on the use of environmental energy converted by the combined wind turbine to drive the heat pump compressor. The possibility of the location of the wind turbine on the roof of a building with attic wall of low potential energy heat pump.

Experimental data on manifestation of the spillover effect, when intercalation of the solid hydrogen into graphite nanofibers, are considered.

In the review are presents the results of experimental studies of superconductors which were obtained by the author with the students and staff of the cryogenic laboratory by basic method of internal friction. Within the proposed model is carried out discussion of the detected physical phenomena. In this paper some of the physical phenomena have the further development and practical application.

There is approach of usage high efficiency ecological technology to prevent and to reduce volumes’ dust ingredient’s substances in emissions of pollutions exhausted in the atmosphere in this article. There contained applying dust separation apparatus in filtering-fluidized bed in building construction and  building industry in this article. It is possible to reduce air emissions of dust pollutions at sufficiently high degree using proposed dust precipitators. The usage of such devices in the cleaning emission treatment’s systems reduces the volume mass of industrial waste production too. These trapped dust cleaning devices with filtering bed of particulate materials (grains, pellets) can be returned to the production cycle. There was fulfilled attempt to make modeling the process of continuous dust capturing in particulate filtering-fluidized granules bed’ devices based on quasi-diffusion description in this article. There was presented developed and studied experimental design gas -spread grid for the process of continuous dust cleaning of aspiration flows in particulate filtering-fluidized devices –  granules, grains in building industry in this paper. It were obtained and performed the regression equation describing the change in the degree of leakage of dust  ζ and the coefficient of aerodynamic drag device ξ depending on some of the basic parameters of the device in different operation modes for cleaning dust device and gas flow based on the mathematical processing of experimental data in this article.

Processes of dielectric relaxation in different types of disordered polar dielectrics such as: relaxor ferroelectrics, dipole glasses, ferroelectric polymers, matrix composites and amorphous solids are described. Fundamental mechanisms, which give main contribution to relaxation polarization, are discussed. 

Results on generation of ultrabroadband terahertz (THz) radiation in band 0.1-2 THz via optical rectification of femtosecond laser pulses in nonlinear tapered crystal are presented. It is shown that placing the LiNbO3 crystal in the free space and in the hollow waveguide both the time and spectral features of the emitted THz field are changed. Several intense spectral regions (at 279 GHz and 1 ТHz) whose frequency depends on the LiNbO3 size are observed. Excitation of ТHz radiation in the tapered nonlinear crystal antenna, partially filling the metal waveguide with the help of an optical femtosecond laser pulse permits the resolution of problems connected with input/output coupling – mode matching and single mode propagation.
