EXPERIMENTAL STUDY OF A LOCAL FURNACE FOR MELTING ALUMINUM FROM USED SOLAR MODULES IN BURKINA FASO
Abdoul Aziz Ouiminga, Boureima Kaboré, Germain Wende Pouiré Ouedraogo, Sié Kam
The manufacture of photovoltaic (PV) panels is evolving increasingly around the world. Used panels are a source
of environmental pollution because recycling them is difficult. In this experimental study, we propose a solution
for recycling aluminum from PV solar modules using a local furnace for melting. First, the frame is separated

Uncooled PV cell under variable light concentration: Determination of profiles of the temperature, the intrinsic properties and the carrier density
Mahamadi SAVADOGO, Pegdwindé Ousséni Fabrice OUEDRAOGO, Adama OUEDRAOGO, Lamine ZIDA, Martial ZOUNGRANA, Issa ZERBO
Studies on concentrated light influence do not take into account the effect of the heating and this proves to be harmful on photovoltaic parameters. The main purpose of this work is to study the effects of light concentration and the heating caused by this concentration on intrinsic properties and carrier density profile. A thermal model of th(...)

Modeling and Validation of Biogas Consumption Prediction in Cook Stove Using a Network Approach
Noufou Bagaya a∗, Issaka Ouedraogo ´ b, Winde Nongue Daniel Koumbem ´ a, Younoussa Moussa Balde´ c, Sette Diop c and Sie Kam ´ a
This study seeks to propose a new model of hearth for the consumption of biogas produced by a biodigester of 4 m−3. The cylindrical furnace is used to heat an empty pot for 3 hours. To do this, the system is subdivided into two sub-systems, the first is the flame, which heats the bottom of the pot. The latter is the second hottest point. The d(...)
