Tarek has joined the Electronic and Interface Materials Laboratory as a postdoctoral research associate to work on the Charged Oxide Inversion Layer (COIL) solar cells project. He completed his MSc in Renewable Energy and Clean Technology at the University of Manchester in 2020 as the top student. He was awarded a departmental success scholarship to fund his PhD focusing on the degradation mechanisms in silicon solar cell materials. During his doctoral studies, he explored the electronic properties of defects responsible for the shortening of the minority carrier lifetime in silicon by means of electrical and optical techniques. His focus was directed towards gallium-doped silicon as well as the dynamics of hydrogen and its role in the degradation mechanisms. Tarek’s published works include the characterization of complexes formed by the interaction of hydrogen with dopants and impurities in silicon as well as their fundamental properties.
