Education
Hassan’s academic training demonstrates a consistent progression toward scientific excellence, beginning with a solid foundation in fundamental physics and culminating in advanced doctoral studies in nanotechnology and renewable energy. After completing undergraduate studies in physics, he pursued master’s degrees with a focus on renewable energies, where he gained expertise in sustainable energy design, installation, and auditing. His doctoral research in physics centers on semiconductor thin films, particularly II-VI and III-V materials such as ZnS, exploring their structural and optical properties through methods including spray pyrolysis, chemical bath deposition, and vapor deposition. Complementing his academic work, he undertook advanced training in Montpellier, France, where he mastered laboratory techniques in spectroscopy, diffraction, and nanomaterials synthesis.
Experience
Parallel to his academic achievements, Hassan has acquired significant professional and leadership experience in teaching, governance, and scientific advocacy. As a lecturer and adjunct faculty member at the University Abdou Moumouni of Niamey, he has taught courses in physics and supervised students in physics, chemistry, and bio-geosciences. He has also taught mathematics and sciences at secondary and preparatory levels, contributing to the training of future scientists. Beyond teaching, he has served in governance roles such as faculty council member, secretary in student unions, and vice-president of university commissions, where he contributed to academic reforms, budget planning, and conflict resolution. His service extended nationally and regionally through leadership in the Société Nigérienne de Physique, the West African Physics Society, and the UEMOA student network, as well as through his involvement in committees on renewable energy, human rights, and youth leadership.
Research Focus
Hassan’s research is primarily dedicated to the study of semiconductor nanostructures, thin films, and their applications in renewable energy and optoelectronic devices. His doctoral investigations focus on zinc sulfide (ZnS) thin films, which hold promise for solar cells and photonic devices due to their wide bandgap and favorable optical properties. He examines synthesis protocols using spray pyrolysis, chemical bath deposition, and vapor deposition, followed by characterization techniques such as X-ray diffraction, Raman spectroscopy, photoluminescence, and scanning electron microscopy. His research explores critical questions on excitonic behavior, donor-acceptor interactions, and the effect of growth conditions on crystal quality, with the aim of improving material efficiency for energy conversion technologies. By integrating experimental approaches with computational tools like MATLAB, Origin Pro, and PVSyst, Hassan advances both theoretical insights and practical applications for sustainable energy solutions.
