EFFECT OF INCIDENCE ANGLE VARYING FROM 0 RAD TO Π/2 RAD AND INTENSITY OF RADIO WAVES ON THE PERFORMANCE OF A SILICON SOLAR CELL
Issa Zerbo, Martial Zoungrana, Mamoudou Saria, Adama Ouedraogo, Dieudonné Joseph Bathiebo
In this work, a one dimensional approach is presented for modelling the effect of the incidence angle, varying from 0 rad to π/2 rad, and the intensity of radio waves on the performance of a polycrystalline silicon solar cell under constant multispectral illumination. By solving the continuity equation in steady state, we derived the expressio(...)

ESTIMATING HEAT AND MASS QUANTITIES TRANSFERED BETWEEN FREE SURFACE WATER AND THE ATMOSPHERE USING THE ENERGY BALANCE METHOD.
P. Florent KIENO and Alfred BAYALA.
We hereby present a study on heat and mass transfer between free surface water and the atmosphere in Burkina Faso. We preferentially chose the city of Ouagadougou to conduct this study. One of the major problems in studying evaporation is how to determine water surface temperature and the flow of water evaporated. We calculated this surface te(...)

One-dimensional study of both electronic and electrical parameters of a silicon solar cell in the presence or not of an electric eld, a magnetic eld, or an electromagnetic eld does not take into account the grain size and the grain boundary recombination velocity. A three-dimensional study, on the contrary, takes those factors into account.(...)

3-D Modeling of Temperature Effect on a Polycrystalline Silicon Solar Cell under Intense Light Illumination
Boubacar Soro, Martial Zoungrana, Issa Zerbo, Mahamadi Savadogo, Dieudonné Joseph Bathiebo
The efficiency of a silicon solar cell is directly linked to the quantity of carrier photogenerated in its base. It increases with the increase of the quantity of carrier in the base of the solar cell. The carrier density in the base of the solar
cell increases with the increase of the flux of photons that crosses the solar cell. One of the m(...)
