ADI method]]>
The two-dimensional transient heat conduction through a multilayers wall made of different materials and thicknesses was numerically resolved. The equations system resolution was carried out by Alternating direction implicit method (ADI). The outdoor and indoor temperatures and the convective coefficients used as boundary conditions in the developed Fortran program were from the Algerian regulatory technical document. After validation of the Fortran program with literature, it was used to studying the influence of different boundary conditions (bottom and top sides), on the thermal insulation in the building, for many configurations of external walls, usually used in building construction at Batna city (Algeria). Results showed that for the configurations that give bad thermal insulation, the conditions imposed on the top and bottom of the wall have practically no influence on the internal temperature of the multilayers wall, however, the opposite is observed for the configurations that ensure good thermal insulation.]]>

non-hydrogenated amorphous silicon]]>
This work deals with the performance of a heterojunction with intrinsic thin layer solar cell by sputtering silicon on p-type crystalline silicon substrate in argon ambient without hydrogen addition. This first effort was an attempt to use cost-effective means to convert light into electricity and to find fabrication processes which use fewer and cheaper materials for the fabrication of solar cells. Since transport mechanisms of amorphous silicon/crystalline silicon heterojunctions are still under investigation, the aim is to examine the behavior of the fabricated samples under electrical and optical constraints. Initial cell characterization includes electrical behavior via current-voltage characteristics and optical investigation via reflectance and absorptance measurements. Results are analyzed in a tentative to follow the absorption, generation and collection processes in the fabricated cell. The heterojunction interface is found to be a limiting factor in the cell performance. Under sun illumination, the open circuit voltage was 140 mV, the short circuit current was of 6 µA and the fill factor was of 42.56 %. Dark current-voltage characteristics indicated a tunneling and/or recombination carrier transport mechanism, while aborptance/reflectance measurements showed a generation process occurring in most in the crystalline silicon-side of the amorphous/crystalline silicon heterojunction. A carrier collection limitation is a very probable origin of the decreased cell generated current.]]>

L’énergie solaire photovoltaïque (PV) est parmi les énergies renouvelables la plus utilisée pour la production de l’énergie électrique. Le point le plus important en ce qui concerne l'intégration des systèmes photovoltaïques au réseau est le convertisseur de puissance, notamment les onduleurs qui ne sont pas tout à fait capables de fonctionner en mode avancé. Les nouvelles techniques en développement permettent d'améliorer les performances des onduleurs en assurant l'intégration correcte des systèmes photovoltaïques en tenant compte des caractéristiques du réseau. D’où, des exigences pour le contrôle avancé de l'onduleur connecté au réseau permettent le contrôle complet de l'énergie photovoltaïque fournie, toute en assurant une bonne qualité d’énergie, un faible Taux de Distorsion Harmonique (THD) des courants injectés dans le réseau et le contrôle de la puissance active et réactive. Ce papier présente, les configurations, la classification et les topologies des différents types d’onduleurs PV connectés au réseau. Un résumé concis des méthodes de contrôle pour les onduleurs monophasés et triphasés est également présenté. Un banc d’essai a été réalisé pour la validation expérimentale des techniques de contrôle proposées et développées.]]>

Arid and semi-arid region]]>
Photovoltaic conversion is an optimal solution for the electrification of rural areas, especially deserts for the abundance of solar energy in these regions. In recent years, many studies have been carried out to maximize the energy productivity of a PV array system and increase its efficiency. However, the arid and semi-arid region is characterized by a climate whose parameters significantly influence the operation of PV installations. This paper presents an overview investigation of the major internal and external factors significantly affecting both the efficiency and the performance of solar cells and the power of PV systems. These factors include the type of PV material, solar radiation intensity received, cell temperature, parasitic resistances, cloud, and other shading effects, inverter efficiency, dust, module orientation, weather conditions, geographical location, and cable thickness. Simulation of a PV system has been carried out in MATLAB-SIMULINK to prove the effectiveness of the proposed modeling method. These simulation results are useful to predict the production of the PV module under real operating conditions.]]>

Stability analysis]]>
The autonomous operation mode of paralleled inverters in microgrids can be intentional or unintentional in order to ensure the continuity of supply. In this mode the voltage and frequency magnitudes are held by local controllers using droop control, this latter is generally considered to be the most adopted technic for the primary layer in a multilayer control structure due to their main feature of sharing the power equally between inverters, without needing communication infrastructure, the design of droop parameters is very crucial because a bad design can lead to the instability of the system. This paper presents a small-signal analysis for an MG composed of parallel-connected inverters in island mode and controlled using the droop method, aiming to analyze the stability by performing eigenvalues and sensitivity analysis which allows obtaining the behavior of the system, analyze the interaction between the different elements and study the influence of the droop parameters on this later which helps in the design procedure, small-signal model and Simulink block model was developed and simulated. Simulation results show a high correspondence and agreement between the model developed using Matlab Simulink-SimPowerSystem library and the developed small-signal model which confirms the validity of this later.]]>

In this study, the hygroscopicity and thermodynamic properties of figs were studied to simulate their hygroscopic behavior during storage and drying. The experimental results were analyzed by the nine models of sorption isotherms. The Peleg model was considered the most appropriate to describe the relationship between the equilibrium moisture content and water activity. The thermodynamic functions such as net isosteric heat sorption, the entropy of sorption, spreading pressure, net integral enthalpy, and entropy were determined. Net isosteric heat of sorption and sorption entropy decreased with increasing moisture content. The heat of desorption is slightly greater than that of adsorption with low moisture content. The integral net enthalpy decreases with the moisture content while the entropy integral net increased. The theory of enthalpy-entropy compensation can be successfully applied to water sorption by fig.]]>

Drying]]>
In Madagascar, the drying of Curcuma consists of exposing them directly to the Sun. This is not always productive. This work aims to provide information on the drying of turmeric by determining the drying curve in order to consider industrial drying. To do this, two steps were conducted: an experiment of drying and modeling of the drying curve by analogy with the empirical model of Bradley. This allowed obtaining the drying curve of Curcuma. The obtaining of this curve allows to predict the behavior of the product in the drying and so to define the necessary energy to bring to dry it and especially, to determine the duration of drying. All this will be able to lead essentially in the theoretical and technical calculations for the realization of the dryer and continuation of the feasibility study of such a project]]>

Orientation]]>
In this paper, the melting and solidification of n-eicosane as a PCM inside two orientations of square containers is investigated numerically, using enthalpy–porosity method. The study reveals how the melting and solidification rate could be affected by changing the orientation of the phase change material container with a constant temperature boundary. It was found that the orientation of the square cavity has a significant effect on the melting and solidification rate of a PCM, the improvement is more than 40% for both cycles. Therefore the orientation of the heat exchange surface is a good control parameter for both the solidification and melting process]]>

This article examines the best fraction of indium (x) and critical depth (H) of a single junction tandem photovoltaic (PV) cell (InxGa1-xN) in the vein to optimize its electrical efficiency. For better investigation, the optical and electronics parameters of a solar cell are determined as a function of the indium fraction and depth of the solar cell, leading to the resolution of the continuity equation and the establishment of the electrical characteristics (short circuit photocurrent, open-circuit photovoltage, maximum electric power). The outlet of our numerical investigations conducted under standard test conditions in the visible spectrum bandwidth of the irradiation, we found that the best indium fraction and the solar cell depth at the optimum electric power point are x=0.6 and H=1m (In0.6Ga0.4N) respectively. Furthermore under normalized irradiation condition (0.1 W/cm2, T=25oC), we found a maximum electric power and efficiency of about 28.53 mW/cm2 and 28.53% respectively.]]>
