Shuaifeng Hu is a postdoctoral researcher at the University of Oxford with an interdisciplinary background in chemistry, materials science, and semiconductor physics. His research focuses on hybrid metal halides, aiming to explore and optimize the properties of this class of materials for novel applications. A significant aspect of his work involves investigating and modifying the surfaces of the metal halide thin films to improve their performance in photovoltaic applications.
His expertise lies in the fabrication of efficient p-i-n perovskite solar cells, with a particular focus on narrow-bandgap (~1.25 eV) mixed-metal tin–lead perovskite solar cells. His research extends to the development of perovskite-containing tandem solar cells, covering "all-perovskite" and "perovskite-on-silicon" multi-junction devices. His current work revolves around understanding the surface properties of perovskite films and their multilayer device architectures. By gaining insights into these surface characteristics, he aims to fabricate cutting-edge photovoltaics, including single-junction perovskite, all-perovskite tandem, and perovskite-on-silicon tandem solar cells, using sustainable fabrication routes.
