Jacques Nébié , Sidiki Zongo , Augustin. Zongo , Guy. Tubreoumya , Zacharie S. Kam , Serge W. Igo , Tizane Daho , Ilyassé Konkobo , Antoine Béré and Belkacem Zeghmati
The present work reports the thermal performance of a box-type solar cooker insulated with kapok
wool, a local plant with a low thermal conductivity. The experimental results obtained indicate that
the absorber plate reached a maximum temperature of 155.2 °C. Moreover, the maximum power of
the cooker was 87.5 W with an efficiency of 35.45 %(...)

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(...)

Energy Performance Analysis of B1-3.5mm Burner Model of Fasobio-15 Biodigester Biogas Cookstoves
Noufou Bagaya1*, Issaka Ouedraogo2, Daniel Windé Nongué Koumbem1, Gwladys Wendwaoga Sandwidi3 and Florent Pelega Kieno1
In Burkina Faso, finding wood for cooking is still a headache for rural households due to the advancing desert. Here, we try to bring a new way for farmers who already have a biodigester and convince those who are reluctant to adopt this work to reduce their dependence on wood. For this purpose, a characterization of the energy performance of(...)
