Influence of Vegetal Roofs on Thermal Comfort in Housing in Sahel Region
Paul Ilboudo, Saidou Sore, Adrien Sanembaye, Jean Marie Compaore, Boubacar Soro, Thierry S. Maurice Ky, Sié Kam, Dieudonné J. Bathiebo
The concern for improving comfort in housing has led man to consider the temperature, which primarily influences thermal comfort inside the building. In a building, all walls are capable of receiving and transferring heat, but the roof contributes significantly to heat exchanges more than the other walls. In this article, we focused on the eff(...)

Modeling the impact of different wavelengths of sunlight on the performance of a silicon photovoltaic (PV) cell
Latifatou Ouoba, Ramatou Saré, Mamoudou Saria, Idrissa Sourabié, Vinci de Dieu Bokoyo Barandja, Martial Zoungrana and Issa Zerbo
Previous studies have experimentally investigated the impact of filtered sunlight or monochromatic LEDs on PV cell performance. However, theoretical analyses of wavelength-specific effects remain limited. This work addresses this gap using a 1-D model to investigate the impact of different wavelengths of sunlight on the performance of a silico(...)

Design and Construction of a Solar/Biomass Hybrid Cooker for Sahelian Climatic Conditions
Iliyassé Konkobo, Jacques Nébié, Lucmane Koala, Boubou Bagré, Armand Bowendkuni Korsaga, Guy Tubreoumya, Ali Diané, Tizane Daho, and Antoine Béré
Solar box cookers are eco-friendly and eliminate the need for wood, but they are not always sufficient to replace biomass stoves. Few studies have explored combining solar and biomass energy in a single system. In our study, we designed a hybrid device that integrates a box-type solar cooker with a biomass combustion chamber. This system prior(...)
