18 May 2023. Many congratulations to Tahmida Huq upon passing her PhD viva (with minor corrections). Tahmida’s thesis was on: "Developing next-generation, non-toxic, inorganic materials for photovoltaics and thin-film transistors”. More specifically, she worked on the PV materials BiOI, which we she showed (with collaborators) to be an excellent indoor light harvesting material and we’ve more recently shown to be a very sensitive X-ray detector material. She also showed the merits of using atmospheric spatial CVD for the growth of p-type Cu2O for thin film transistors. Tahmida is now a research engineer at ASML in the Netherlands.
