3-D MODELLING OF ELECTRICAL PARAMETERS’ EFFECTS ON THE HEATING OF THE BASE OF AN INTENSE LIGHT ILLUMINATED POLYCRYSTALLINE SILICON PV CELL
B. Soro, M. Savadogo, B. Zouma, K. E. Tchedre, I. Sourabie, I. Zerbo, M. Zoungrana, D. J. Bathiebo
Performances of a solar cell are significantly influenced by the heating of the base. Two phenomena contribute to the heating of the base of a PV cell: the heat due to the transfer by conduction of the solar energy radiation received by the surface of the PV cell and the heat generated inside the solar cell by various phenomena related to the(...)

Experimental Evaluation of Thermals Performancesof The Solar Dryer with Parabolic Trough Collector
B. Magloire Pakouzou, N. Landry M'Bouana, M. S. Thierry Ky, Jean M'Boliguipa and D. Joseph Bathiébo
A cylindrical-parabolic solar-thermal converter, with 0.5m 2 of capture surface, was manufactured and attached to a furnace, constituting an indirect solar dryer. Thermal balances of the elements of the receiver, housed in the focal point of this collector, are settled. A campaign of vacuum tests of this dryer indicated temperatures of the hea(...)

Fati Amadou Oumarou, Adama Ouedraogo, Sikoudouin Maurice Thierry Ky, Ramchandra Bhandari, Amadou Konfe, Ramatou Konate, Rabani Adamou, Dieudonné Joseph Bathiebo, Sié Kam
Thermal comfort is one of the most important requirements that scientists
and building designers must meet to ensure the indoor air quality knowing its
importance on productivity and the health of occupants. However, it has
never been of great concern for architects and a rchitectural historians and
seldom explores it. Buildings are th(...)

LIGHT CONCENTRATION SOLAR CELL: TEMPERATURE PROPER AND DYNAMIC EFFECTS ON ELECTRICAL PARAMETERS DETERMINED BY USING J-V AND P-V CHARACTERISTICS
MAHAMADI SAVADOGO, AMADOU KONFE, IDRISSA SOURABIE, BOUBACAR SORO, RAMATOU KONATE, MARTIAL ZOUNGRANA, ISSA ZERBO, DIEUDONNÉ JOSEPH BATHIEBO
The solar cell is assumed to be under light concentration (C=50 Suns) which leads us to take into consideration the electric field induced by electrons concentration gradient. We also take into consideration temperature influence on electron and hole diffusion parameters, on carrier generation rate, on carrier intrinsic concentration and on si(...)

Modeling the Impact of Desert Aerosols on the Solar Radiation of a Mini Solar Central Photovoltaic (PV)
Wend Dolean Arsène Ilboudo1*, Issaka Ouedraogo1, Windé Nongué Daniel Koumbem2, Pèlèga Florent Kieno2
This work focuses on modeling the impact of desert aerosols on a mini central solar photovoltaic (PV). Our studied physical model is comparable to a multilayer. We have described and discretized the mathematical equations which govern the physical model. Also, we analyzed the influence of the parameters τa and X on the solar radiation received(...)

Caractérisation des champignons macroscopiques par spectroscopie d'absorption UV-visible
Ouédraogo Tongonmanegde Leonard, Sougoti Moussa , Kam Sié Zacharie, Zongo Sidiki, Bado Fabrice, Koulidiati Jean, and Béré Antoine
In this paper, we present a spectroscopic study to differentiate the macroscopic mushrooms: Russula Congoanan (Rc), Lactifluus
gymnocarpoides (Lg) and Amanita amasasiensis (Aa). The analysis of the
spectra, acquired by absorption spectrophotometry in the UV-visible range of the extracts obtained by hydration of dry mushroom fragments, shows(...)

Thermal Behavior of the Natural Convection of Air Confined in a Trapezoidal Cavity
Windé Nongué Daniel Koumbem1*, Issaka Ouédraogo2, Noufou Bagaya1 and Pelega Florent Kieno1
The thermal behavior of air by natural convection in a confined trapezoidal cavity, one of the walls of which is subjected to a constant heat flow in hot climates, has been analyzed numerically. The heat and mass transfers are carried out by the classical equations of natural convection. These equations are discretized using the Finite Differe(...)

Structural and physicochemical properties of dust collected on PV panels surfaces and their potential influence on these solar modules efficiency in Dakar, Senegal, West Africa
Mamadou Simina Drame, Dialo Diop, Kharouna Talla, Moussa Diallo, Balla Diop Ngom, Bado Nebon
Two dust samples were collected from the same solar panels on June, 2017 in Dakar. The first was sent to Ithemba Labs (South Africa) and the second to Lincon Nebraska University (USA) for structural and physical properties study. This work aims to evaluate the dust impact on PV efficiency. The study shows that these particles have a non-spheri(...)

Experimental Study of an Indirect Solar Dryer Using a New Collector System. Application to Mango and Ginger Drying
Thierry Sikoudouin Maurice Ky, Damus Abdoul Aziz Traore, Bienvenu Magloire Pakouzou, Boureima Dianda, Emmanuel Ouedraogo and Dieudonne Joseph Bathiebo
In this paper, an indirect solar dryer using a new type of collector is studied. The collector is built with hemispherical concentrators with an axially-centered Fresnel lens placed on top of each. That allows the collector's aperture area of 0.32m2 to fully contribute to the hot spot generated in the hemispherical concentrators. The dryer was(...)
