The use of vegetable oils in burners represents an attractive alternative to the use of heating fuel oil (HFO)
in heat production for domestic heating, small industrial units, drying of various products etc. In this
work, a characterization of the combustion of cottonseed oil in a modified burner (type Riello 40N10)
was performed to assess(...)

This work concerns the study of the influence of air flow on yields of gas emissions during the combustion of a mixture of millet stalks and polyethylene bags in a prototype of kiln. During these investigations, we looked at the rate of residual oxygen (O2) and emissions of carbon dioxide (CO2) and nitrogen monoxide (NO) as a function of prima(...)

SILICON SOLAR CELL UNDER ELECTROMAGNETIC WAVES IN STEADY STATE: ELECTRICAL PARAMETERS DETERMINATION USING THE I-V AND P-V CHARACTERISTICS
O. SOW, I. ZERBO, S. Mbodji; M. I. NGOM; M. S. DIOUF and G. Sissoko
The principal effect that limits solar cell efficiency is the recombination of the photo generated charge carriers before they participate to energy current. These recombination are characterized by electronic (recombination) and electric interdependent parameters that influence the solar cell quality and conversion efficiency.

DETERMINATION IN 3D MODELLING STUDY OF THE WIDTH EMITTER EXTENSION REGION OF THE SOLAR CELL OPERATING IN OPEN CIRCUIT CONDITION BY THE GAUSS’S LAW
E. SOW, S. MBODJI, B. Zouma, M. Zoungrana, I. Zerbo, A. Sere and G. SISSOKO
In this article, we are discussing the Gauss’s law used to determine the width emitter extension region of the solar cell operating in open circuit condition. Taking into account the grain size (g), the grain boundary recombination velocity (Sgb) and the emitter doping density (Nemitter), the Gauss’s Law helped us to calculate the width emitte(...)
