Effect of Base Thickness on the Performance of a Polycrystalline Silicon-Based Semiconductor Radial N/P Junction Solar Cell in the Static Regime under Monochromatic Illumination
Aboubacar Savadogo, Bernard Zouma, Ramatou Konate, Cyrille Constant Moyenga, Raguilignaba Sam
In this work, the importance of the base thickness on the performances of a radial n/p junction solar cell-based polycrystalline silicone is shown. Thus, from a theoretical study under monochromatic illumination in a static regime, we established new analytical expressions of electrical parameters. By simulations on Mathcad 15 software with ph(...)

Evaluation of the Performance of Lithium-Ion Accumulators for Photovoltaic Energy Storage
Toussaint Tilado GUINGANE , Dominique BONKOUNGOU, Eric KORSAGA, Dieudonné Simpore, Soumaila Ouedraogo, Zacharie Koalaga, François Zougmore
In a context of climate change exacerbated by the increasing scarcity of fossil fuels, renewable energies, in particular photovoltaic solar energy, offer a promising alternative. Solar energy is non-polluting, globally available and the
most widely distributed resource on Earth. However, the intermittency of this energy source considerably li(...)

Performance Analysis of a Radial N+/P Silicon Solar Cell in Steady State and Monochromatic Illumination
Aboubacar Savadogo, Bernard Zouma, Bruno Korgo, Ramatou Konaté, Sie Kam
In this paper, we investigate theoretically a radial n+/p silicon solar cell in steady state and monochromatic illumination. The purpose of this work is to analyze the effect of the cell base radius on its electrical parameters. The continuity equation in cylindrical coordinates is established and solved based on Bessel functions and boundarie(...)

Investigation of the Behavior of a Photovoltaic Cell under Concentration as a Function of the Temperature of the Base and a Variable External Magnetic Field in 3D Approximation
Boubacar Soro, Adama Ouedraogo, Mahamadi Savadogo, Ramatou Konate, Guyserge Tchouadep, Martial Zoungrana, Sié Kam
The photovoltaic (PV) cell performances are connected to the base photogenerated carriers charge. Some studies showed that the quantity of the photo-generated carriers charge increases with the increase of the solar illumination.
This situation explains the choice of concentration PV cell ( C = 50 suns ) in this study. However, the strong p(...)

Numerical Study of Heat Transfer in a Differentially Heated Cavity
Amadou Konfe, Adrien Sanebaye, Alfred Bayala, Sié Kam
Laminar natural convection is studied in a square cavity filled with air whose
two vertical sides are subject to a temperature difference, while the other two
horizontal sides are adiabatic. The hot and cold wall temperatures are kept
constant. We have presented a dynamic and thermal study of pure natural
convection for different values of(...)

Traoré Hortense1* , Segda Bila Gérard1 , Dipama Jean-Marie
This study aims at contributing in the characterization of the quality of the underground waters in the
Massili sub basin, through the analysis of some pesticides in 40 water samples from some shallow
wells and boreholes. The gas chromatography method, using the GC-HP5 (30 m, 0.25 mm, 0.25 µm)
coupled with the mass spectrometer, and the(...)

Evaluation of Water Losses by Evaporation in the Nakanbe Basin
Bayala Alfred, Kabre Sayouba, Yonli Hamma Fabien, Chesneau Xavier, Thierry Sikoudouin Maurice Ky, Zeghmati Belkacem, Kieno P. Florent, Kam Sié
A numerical approach to heat and mass transfer in a large water reservoir is
presented. This water reservoir is likened to a parallelepiped reservoir whose
vertical and lower walls are adiabatic and impermeable. The equations that
govern natural convection in water are solved by the finite volume method
and Thomas’salgorithm. The adequacy(...)

Diagnostic du fonctionnement de la Station d’Epuration de Kossodo : approche par la caractérisation des eaux usées brutes entrant
Mariam SAWADOGO*, Bila Gérard SEGDA, Paul Windinpsidi SAVADOGO, Antoine BERE
La Station d’Epuration (STEP) de Kossodo est confrontée à un problème de
fonctionnement entrainant le non-respect des normes de rejet recommandées
par le Burkina Faso et par l’OMS. Malgré cette situation, les eaux issues de
la station sont utilisées pour la production maraichère. De même, ces eaux
reversées dans la nature sont suscepti(...)
