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 been explored, and the requirements for high-effic(...)

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 (finite element method). The implementation of the m(...)

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 Blanchart
The 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 (34%). The sand SAB is mainly composed of quartz(...)

Numerical Characterization of Cu(In,Ga)Se2 Solar Cells Using Capacitance-Voltage and Capacitance-Frequency Characteristics
Daouda Oubda, Marcel B. Kebré, Soumaïla Ouédraogo, François Zougmoré, Frédéric Ouattara, Zacharie Koalga
The paper presents the effects of buffer layer thickness, operating temperature, and series resistances on the capacitance-voltage and capacitance-frequency (C-f) characteristics of the standard ZnO/CdS/OVC/Cu(In,Ga)Se2/Mo thin film solar cells.
The numerical simulation tool used is a one dimensional program: Solar Cell Capacitance Simulator(...)

Numerical Simulation of Cu(In,Ga)Se2 Solar Cells Performances
Daouda Oubda, Marcel Bawindsom Kébré, François Zougmoré, Donatien Njomo, Frédéric Ouattara
This paper presents a numerical characterization of copper-indium-gallium-diselenide thin film solar cells using one dimensional simulation program (SCAPS-1D). We have performed an optimization of the performances of the standard Mo/Cu(In,Ga)Se2/CdS/ZnO solar cells using current-voltage and quantum efficiency methods. With a CuIn0.7Ga0.3Se2 ab(...)

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 Zougmoré
We 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 layer, were varied to achieve the optimal performa(...)

Une étude comparative des caractéristiques électriques et énergétiques ont été faite entre les photopiles CdS/CIGS,
ZnO/CIGS et ZnS/CIGS en utilisant SCAPS-1D. La cellule solaire en couches minces CIGS sans cadmium est de type
Mo/CuIn0.7Ga0.3Se2/ZnO1-xSx/OTC. L’étude approfondie de la couche tampon alternative ZnO1-xSx, montre qu’une
