Impact of the Thicknesses of the p and p+ Regions on the Electrical Parameters of a Bifacial PV Cell
Ramatou Konate, Bernard Zouma, Adama Ouedraogo, Bruno KorgoThe present paper is about a contribution to the bifacial PV cell performances improvement. The PV cell efficiency is weak compared to the strong energy demand. In this study, the base thickness impacts and the p+ zone size infl u-ence are evaluated on the rear face of the polycrystalline...

SIMULATION OF THE OKRA DRYING PROCESS IN A SOLAR TOWER DRYER
Germain Wende Pouire Ouedraogo , Boureima Kabore , Nebon Bado , Vincent Zoma , Sie Kam and Dieudonne Joseph BathieboThis work presents the simulation of the drying air flow in a solar tower dryer as well as the okra drying process with FORTRAN software. The explicit Euler method was used for solving the heat transfer and mass transfer equations. The heat transfer equations reflect the flow of hot air from the...

Measurements of natural radioactivity and exposure rates in soil samples from Ouagadougou, Burkina Faso
Z. Yaméogo, D. Nabayaogo, O. Kaboré, C. Bangou , I. Zerbo, M. ZoungranaNatural radioactivity could be found in various degrees in all media in the environment (water, soils, vegetation, food), and depending on the activity and concentration of radionuclides dealt with, the principal concern is the consequence of exposure to low doses and low dose rates. In this...

Comparative study of thermophysical parameters of different types of upholstery wood and the influence of density on combustion parameters at microscale
Abdoul Fayçal BAGUIAN, Salifou Koucka OUIMINGA, Sampawinde Augustin ZONGO, Ibrahim Harouna GADO, Rodolphe SONNIERThe fire behaviour of five types of wood was studied on a microscale. Some thermophysical parameters such as thermal conductivity, effusivity and diffu- sivity were also evaluated. The microscale analysis is based on the analysis of several parameters such as the assessment of heat released...
