Xin Cui received her Ph.D. degree in Photovoltaic Engineering from the University of New South Wales (UNSW) in 2020. She was involved in the fundamental study of atomic layer deposition (ALD) process and its application for thin-film solar cells, achieving a series of world-record efficiency in earth-abundant CZTS solar cells without any toxic constitutes. She is now an Australian Centre for Advanced Photovoltaics (ACAP) Postdoc fellow in UNSW. Her research focuses on the development and characterization of photovoltaic materials and devices. Her project is entitled “Interface Engineering by Atomic Layer Deposition for High-performance Earth-abundant Solar Cells” and aims to develop high-performance earth-abundant solar cells through interface engineering by ALD.
