Effet de l’assombrissement centre-bord sur les raies spectrales:Cas typique des étoiles de type G
Fabrice BADO, Zacharie Sié KAM , Nekolgne Aymard BADOLO , Baguima Gilbert BAYALA, Jean KOULIDIATI
We present the impact of center-to-limb darkening (𝜀𝑖) on spectral line profiles of G-type stars through systematic analysis of cross-correlation function broadening. Using solar-type stellar spectra, we examine how center-to-limb darkening coefficients affect the measured full width at half maximum (FWHMCC) and derived rotational velocities ((...)

Alternate Method for Calibration of PRDs by Means of Gamma Radiation Emitted by Radionuclides
Z. Yaméogo, D. Nabayaogo, A. Razakou, Zerbo, M. Zoungrana
adioactive sources have many beneficial uses across various socioeconomic sectors, but these sources pose safety and security risks. The detection and measurement of ionizing radiation constitute an important pillar not only to ensure radioprotection but above all to prevent illicit trafficking of radioactive materials. However, to guarantee t(...)

Investigation of SnS thin film as a BSF layer in Cu2ZnSnS4-based solar cells: a strategy to improve efficiency using SCAPS-1D
Y. Coulibaly,* , S. Ouedraogo, D. Oubda, R. Sam, F. Zougmore
Photovoltaic devices based on the quaternary material Copper-Zinc-Tin-Sulfide (Cu2ZnSnS4) commonly called CZTS have shown promising conversion efficiency in the last decade. However, this conversion efficiency still remains below expectations due to several factors including the high recombination rate at the CZTS/Mo rear contact. Indeed, this(...)

Influence of Climatic Parameters on the Performance of Polycrystalline and Monocrystalline Silicon Photovoltaic Solar Modules: The Case of the City of Koudougou
Eric Korsaga , Nébon Bado , Dominique Bonkoungou, Toussaint Tilado Guingane, Haidara Savadogo, Sidpendyaolba Sosthene Ldg Tassembedo, Zacharie Koalaga
Monocrystalline and polycrystalline silicon-based modules are commonly used in Burkina Faso, particularly in the city of Koudougou, to generate electricity. However, climatic parameters affect the performance of these modules. It is therefore necessary to conduct a comparative study between polycrystalline and monocrystalline silicon-based pho(...)

Study of the solar energy potential in the City of Mamou (Republic of Guinea)
Mariama Bah, Abdourahmane Diallo, Ramatou Saré, Abdoul Kadri Diallo, Mohamed Nfaoui, Hambaliou Baldé and Issa Zerbo
The Republic of Guinea, like other intertropical countries, receives significant levels of global solar irradiance. However, accurate quantification of local solar energy potential is essential for its optimal utilization. In this study, the solar energy potential of the City of Mamou (Republic of Guinea) was assessed using three methods for a(...)

Optimization of a Building's Indoor Temperature and Sensitive Air Conditioning Loads Using the BLT Parpaing Hollow Double Wall
Daouda Sawadogo , Benjamin Kiéma and Ousmane Coulibaly
In hot, dry tropical climates (sahelian), such as Ouagadougou (Burkina Faso), high demand for air conditioning in buildings poses a major energy challenge. This study aims to optimize the indoor temperature and sensible air conditioning loads of a typical three-bedroom F3 building with cavity walls, using a double-wall system combining lightwe(...)

Proposal of Models for Global Solar Radiation Estimation in Burkina Faso
Ladifata Mogmenga, Goumwêndkouni Gilbert Nana, Salifou Ouédraogo,Thierry Sikoudouin Maurice Ky, Bouchaib Hartiti, Sié Kam, Joseph Dieudonné Bathiebo.
The solar data used to size installations for energy needs are most often oversized. The data used are either old or suffer from the effects of climate change or from data extrapolated to a whole region. For a country with a strong sunshine all year round, it is good to compare the many models that exist to find the most suitable for the count(...)
