Contribution to the design of a pottery kiln using as fuel a mixture of cellulosic and plastic materials : influence of the proportion of plastic on the emissions of NO, CO2, O2
Salifou K. Ouiminga1*, Thomas Rogaume2, Alfa Oumar Dissa1, Samuel Ouoba1, Tizane Daho1 , Jean Koulidiati1
This paper concerns the study of the influence of the proportion of plastic from polyethylene, on the yields of gas emissions during the combustion of the mixture of “millet stalks and polyethylene plastic bags”, in a prototype of kiln of potters. During these investigations, we looked at the rate of residual oxygen (O2) and emissions of carbo(...)

Silicon solar cell under electromagnetic wave in steady state: effect of the telecommunication source's power of radiation
I Zerbo, M Zoungrana, A D Seré, F Zougmoré
The characterisation of minority carriers’ recombination parameters is important to design any optoelectronic component, since they play an important role in the device performance. Many diagnostic techniques, steady state, quasi-steady state, transient and modulation methods for both the experimental and theoretical measurement have been deve(...)

3D modelling of magnetic field and light concentration effects on a bifacial silicon solar cell illuminated by its rear side
M Zoungrana, I Zerbo, F Ouédraogo, B Zouma, F Zougmoré
According to their installation places, the solar cells are often under the effect of the electro-magnetic field coming from outside sources as telecommunication antennas, radio antennas... These magnetic fields have a big influence on the distribution and mobility of charge carriers in the base of the solar cell and therefore on its efficienc(...)
