Chiral halide perovskites, known for their unique combination of chirality and excellent semiconducting properties, have emerged as a compelling class of materials for investigating quantum phenomena, such as chiral-induced spin selectivity (CISS) and chiral optical...
Two-dimensional (2D) organic–inorganic hybrid iodide perovskites have recently been proposed as stable alternatives to their three-dimensional (3D) counterparts for various promising applications, including photovoltaics (PV), light-emitting diodes (LEDs), and...
Halide perovskites have captivated scientific interest due to their exceptional optoelectronic properties and potential in next-generation energy applications. However, their propensity for instability poses significant challenges for practical use. Defects dynamics...
With the tunability of perovskites through compositional alloying being one of their most attractive properties, the photoinstability arising from the mixing is a very serious drawback. Specifically, in mixed halide perovskites a light induced halide segregation is...
Light emitting diodes (LEDs) are one of the many possible applications for metal halide perovskites. Despite their many advantages, the well-known instability issue persists in these devices, with the ion migration being a major cause of degradation. Inspired by the...
Together with our experimental collaboration Prof. Xinhui Lu (the Chinese University of Hong Kong), Haibo Xue studied the impact of the crystallization kinetics on the quality of the perovskite films. By combining in-situ X-ray scattering (GIWAXS) and DFT...
