I investigate the vapour deposition technique for the fabrication of metal halide perovskites, a novel class of semiconducting materials, for a broad range of applications, including
- All-vacuum-deposited metal halide perovskite single-junction solar cells
- Novel device concepts beyond the conventional single-junction architecture
- Light-emission devices and heterostructures from wide-bandgap inorganic semiconductors
I also utilise advanced spectroscopic techniques in probing fundamental photo-physical and crystallographic properties of metal halide perovskite thin films and solar cell devices. Particularly, I am interested in Fourier Transform Photocurrent Spectroscopy to extract sub-bandgap features of perovskite solar cells.
