  • Influence of CdS Buffer Layer Thickness on the Photovoltaic Parameters of
           Solar Cells
    • Authors: A. G. Komilov
      Pages: 308 - 309
      Abstract: The paper presents the results of a study on the optimization of the CdS buffer layer thickness for the production of high efficiency CIGS solar cells by analyzing the photoelectric parameters of elements with different thicknesses of the CdS layer. The difference in the efficiency of elements with CdS layer thicknesses of 20 and 80 nm was 30% (increase), and 50% (decrease) for elements with CdS layer thicknesses of 80 and 120 nm.

  • Study of Sedimentation Process in Nanofluids with Various Concentrations
           of SiO 2 and Al 2 O 3 Nanoparticles
    • Abstract: This work focuses on the preparation of nanoliquids with application of nanoparticles in order to study sedimentation processes in suspensions chosen. Nanoliquids on the basis of SiO2 and Al2O3 nanoparticles with sizes of 50 nm are prepared at their various concentrations using water as a basic liquid. The sedimentation process of the suspension in a steady state and for a long time has been monitored. In accordance with preliminary tests, sedimentation in SiO2-based nanoliquids is slower than that in nanoliquids on the basis of Al2O3 nanoparticles. The monitoring for 72 h of sedimentation of nanoliquids prepared using a two-step method with application of two types of SiO2 nanoparticles with sizes of 12 nm and 16 nm, as well as Al2O3 with a size of 50 nm, reveals that sedimentation and agglomeration processes in the considered nanoliquids depend to a large extent on the size and concentration of nanoparticles. The optimal sizes of particles and their concentrations in the suspension result in a very weak sedimentation.

  • Modeling of the Turbulent Heat and Mass Transfer in the Receiver Systems
           of the Solar Parabolic Trough Modules
    • Abstract: Numerical modeling of the flow dynamics and heat exchange in the tube receiver of a solar parabolic trough module (PTM) has been performed. The study is based on a dimensionless mathematical model that describes turbulent conduction of heat and momentum. An analysis has been carried out and a turbulence model has been selected. The proposed model describes the features of heat exchange near the wall most accurately. A numerical algorithm and Fortran program have been developed on the basis of the mathematical model. The major geometric, dynamic, and energy parameters of the PTM receiving system have been determined. The results can be useful in designing solar energy systems with parabolic trough concentrators (PTC) of different power and purpose.

  • Influence of Meteorological Factors on the Thermal Loss Coefficient of
           Light-Absorbing Heat Exchange Panels of Flat-Plate Solar Water Heating
           Collectors through Transparent Coatings of Their Casings
    • Abstract: The results of computational studies aimed at determining the coefficient of thermal losses of light-absorbing heat-exchange panels (LAHP) of flat-plate solar water-heating collectors (FPSWHC) through their translucent coatings (TC) are presented. The calculations take into account the effect of free and forced convection on the external surface of the TC, as well as on the convective heat transfer coefficient and the FPSWHC tilt, the atmospheric transparency, and the air humidity on the total heat transfer coefficient from the external surface of the TC to the environment. An example is given to test the proposed approach for practical use to determine the values of \(~\alpha _{{{\text{i}}{{{\text{n}}}_{{{\text{w}} - {{c}_{1}}}}}}}^{\Sigma }\) , \(\alpha _{{{\text{ex}}{{{\text{t}}}_{{{{c}_{2}} - {\text{amb}}}}}}}^{\Sigma }\) , and their convective and the radiant components, and also the degree of their influence on the value of \({K}_{{{{c}_{{{\text{w}} - {\text{amb}}}}}}}^{~}\) .

  • Performance Analysis of an Inverted Trapezoidal Flume Shaped Photovoltaic
           Thermal System
    • Abstract: The photons in the solar spectrum with energy equal to or higher than the band gap energy of the solar cell material are potentially useful for photo electricity. However, as most of the commercial solar cells have negative thermal coefficients; during operation, the unused photons cause thermal losses in these solar cells, and affect their electrical conversion efficiency. To overcome these losses, combined Photovoltaic Thermal systems (PVT) are developed. In these systems, heat is extracted from the PV module to improve its performance. This extracted heat is used separately for thermal applications. Thus, the system gives both electrical and thermal output simultaneously. Several such PVT systems have been reported in the past. In the current study, an inverted trapezoidal flume shaped PVT system is designed. The system is equipped with the flat mirror reflectors from all sides. Water is used as working medium to extract the heat from the PV module. The performance of the system is analyzed experimentally at Nagpur [21° N, 79° E] for different operating conditions. The experimental results had shown significant improvement in the electrical efficiency of PV module. Maximum average electrical efficiency and maximum overall efficiency of the system were found to be 10.42 and 62% respectively. Constructional details of the system and the performance analysis are discussed in this article.

  • Transmission of Solar Radiation by Semicylindrical and Segmented
           Transparent Protections
    • Abstract: Transparent protection (TP) is one of the basic elements of low-potential solar installations. The problem of determining the flux coefficients that allow one to calculate the solar flux entering through the TP is considered. An algorithm and program are developed for determining the flux coefficients for film semicylindrical and segmented TP. It is shown that the meridional orientation of a semicylindrical TP is more efficient than latitudinal, while for a segmented TP, the latitudinal orientation is more favorable.

  • Managing Spatial Orientation of Photovoltaic Module to Obtain the Maximum
           of Electric Power Generation at Preset Point of Time
    • Abstract: To evaluate the possibility of obtaining the maximum of electric power generation at a preset point of time by varying the spatial orientation of photovoltaic modules, its effect on the amount of utilized solar radiation was studied. The experiment was conducted by the example of Zernograd, Rostov oblast, Russia, with specially designed research equipment. The analysis of input of solar radiation to surfaces with different spatial orientation revealed that, owing to different combinations of spatial placement of the receiving site with respect to cardinal directions and the horizon line, it is possible to shift the maximum of power takeoff with photovoltaic modules relative to midday to the morning and evening time about by 4.5 h.

  • Numerical Investigation of Thermo-Hydraulic Characteristics of Non-Uniform
           Transverse Rib Roughened Solar Heater
    • Abstract: A 3-D computational fluid dynamics (CFD) investigation on heat transfer and fluid flow of solar air heater duct roughened with transverse rib of non-uniform cross-section of square wave profile has been carried out using ANSYS Academic Research CFD 15.0. For comparison, transverse rib of uniform square and circular cross-section has also been investigated. Relative roughness pitch and relative roughness width of rib roughness have been taken as 10 and 85 respectively. Relative roughness height and Reynolds number were varied from 0.015–0.043 and 3000–15 000, respectively. The present CFD methodology has been validated with the experimental results. The maximum augmentation in Nusselt number over that of smooth duct was 2.2 and the corresponding enhancement of friction factor was 3.4 times.

  • Analytical Performance Study of Fixed Speed Wind Turbine
    • Abstract: Fixed speed wind turbines have the advantage of being robust and reliable. They allow a direct connection to the electric. The purpose of the article is to study the aerodynamic behaviour and determine the performance of a fixed speed wind turbine. The work presents an analysis method based on the theory of blade element moments (BEM). The variation of aerodynamic parameters is studied for a wide range of wind speeds. A case study is conducted for the design of a wind turbine adapted to the Adrar site which is located in the Algerian Sahara. The results obtained showed that the wind turbine has maximum efficiency just at the design speed. For speeds higher than the design speed, the efficiency is reduced by the stall effect with decreases in torque due to the fall of the lift force. At wind speeds lower than the design value, the thrust effect increases, which puts the rotor under high mechanical stress and blade rotation decreases with low efficiency.

  • Estimation of Monthly Average Daily Global Solar Radiation Using
           Meteorological-Based Models in Adrar, Algeria
    • Abstract: This paper presents a systematic approach to empirical model selection for the global solar radiation (GSR) estimation considering the Algerian town of Adrar. The approach is based on various meteorological variables. The accuracy of the selected model is validated using GSR measurements in the considered location (i.e. Adrar) through eight statistical indicators. Long-term six-parameter data measurements are collected. The collected measurements are divided into two subsets; the first subset (from year 2009 to 2013) is used for the modeling purpose, while the second subset (years 2014–2016) is used for the model evaluation purpose. The results show that the statistical performance of the traditional Angström formula for GSR estimation can be significantly improved by including the effect of the maximum and minimum temperatures in the GSR empirical models. In addition, the results show that excluding the cloud cover from the empirical models significantly reduces the statistical performance of these models.
