Required CIGS and CIGS/Mo Interface Properties for High-Efficiency Cu(In, Ga)Se2 Based Solar Cells
Ouédraogo, S. , Kébré, M. , Ngoupo, A. , Oubda, D. , Zougmoré, F. and Ndjaka, J.In this work, we have modeled and simulated the electrical performance of CIGS thin-film solar cell using one-dimensional simulation software (SCAPS-1D). Starting from a baseline model that reproduced the experimental results, the properties of the absorber layer and the CIGS/Mo interface have...

Numerical study on heat and mass transfers on a CEB (compressed earth blocks) wall in a sahelian context
Kabré, S., Kebré, M. B., Ouédraogo, S., Naon, B., Koalaga, Z. & Zougmoré, F.Numerical modelling of coupled heat and mass transfer within a CEBs wall is presented. Based on Luikov's work, a mathematical modelling of the transfers mechanisms has been established. Temperature and moisture content were chosen as the main way of transfer. A numerical approach was applied...

Characterization and use of raw materials from Burkina Faso in porcelain formulations ; Results in Materials
Youssouf Sawadogo, Lamine Zerbo, Moustapha Sawadogo, Mohamed Seynou, Moussa Gomina, Philippe BlanchartThe use of three mineral materials from Burkina Faso in the formulation of porcelains has been studied. The characterization results showed that the clay NONG contains kaolinite (62%), illite (18%), quartz (17%) and rutile (1%). The pegmatite PEG contains albite (17%), muscovite (44%) and quartz...

Optimization of copper indium gallium di-selenide (CIGS) based solar cells by back grading
S. Ouédraogo, R. Sam, F. Ouédraogo, M. B. Kebré, JM. Njaka, F ZougmoréWe performed modeling and simulation of Cu(In,Ga)Se2 (CIGS) thin film solar cell, using SCAPS-1D device simulator, and we especially investigated the influence of absorber back surface region grading. The band-gap in the back surface region, as well as the thickness of the back surface grading...
