Researchers at the University of Cambridge have developed a precise layer-by-layer vapor-phase growth method for halide perovskites, specifically CsPbBr3, on a 2D perovskite single crystal. This advancement could lead to more thermally stable perovskite solar cells, with scalable, solvent-free, and industrially compatible processes suitable for various optoelectronic applications. The research also demonstrated that uniform thickness control allows for tunable band offsets, improving charge transport and recombination dynamics. The team is now focused on integrating these structures into fully functioning devices such as solar cells and LEDs, offering promising solutions for advancing renewable energy technologies.
