Kossi NAPO, University Professor, is the Head of the Solar Energy Laboratory of the University of Lomé, National Coordinator of the UNESCO Chair on Renewable Energies of the University of Lomé, Head of the Doctoral Training in Material Sciences of the University of Lomé, after his studies in solid state physics (thin films) at the University of Nantes. Throughout his career, he has been mainly concerned with renewable energies. Thus he actively participated in some research projects such as the:  

• Optimization by doping of the properties of thin films of ZnO, SnO, InO obtained by simple techniques. 
• Development and characterization of sintered silicon layers for photovoltaic applications and physical characterizations 
• Identification of thermo-physical and thermo-mechanical parameters of anisotropic materials: application to photovoltaic panels 
• The implementation of solar schools in Togo 

These projects have led him to collaborate with research teams in France (Nantes, Poitiers, Nîmes, Perpignan, Marseille) in the Maghreb (Algeria, Morocco, Tunisia); in Africa (Senegal, Benin, Ivory Coast, Burkina Faso, Nigeria, Congo Brazaville, Gabon, Central African Republic, South Africa) and in Canada (Montreal and Trois Rivières). He is the co-author of several publications, and has participated in numerous international scientific events. He is currently an expert of the UEMOA and the African Union in the field of energy.
