In 2019, I completed my Bachelor degree at University of Liverpool with a final year research project at the Stephenson Institute for Renewable Energy under supervision of Prof. Tim Veal. During this project, I completed a photoemission study of Sb2Se3 single crystals, comparing theoretical density of states predicted by density functional theory, and the valence band spectra delivered by photoemission spectroscopy. I then spent a year in industry where I worked as a Laser Test Engineer, assembling, benchmarking and stability testing pulsed and Q-switched Nd:YAG laser systems. In 2020, I returned to academia to begin my PhD studies at the Stephenson Institute for Renewable Energy at University of Liverpool, under supervision of Dr. Jon Major. The field of my PhD was in the development of Sb2Se3 thin-film solar cells deposited via close-space sublimation. My project focused on optimising selective charge transport at the TiO2/Sb2Se3 interface, which was considered a key performance loss pathway. Upon completion of my PhD in late 2024, I joined TalTech's Laboratory for Thin Film Energy Materials as a Postdoctoral Researcher in January 2025. In this role I am developing Sb2S3 thin-film solar cells, with a focus on minimising optical losses and engineering transparent back contacts for semi-transparent and tandem applications. I have experience with a variety of deposition and characterisation methods including; Magnetron sputtering, glovebox solution spin-coating, close-space sublimation, thermal evaporation, ultrasonic spray-pyrolysis, J-V, EQE, C-V, photoemission spectroscopy, Raman spectroscopy, Electron microscopy, X-ray diffraction and optical spectrophotometry.
