KAUST researchers in the Functional Materials Design, Discovery & Development group have discovered a minimal edge transitive net with high connectivity. This net was used as a blueprint for the design and construction of metal-organic frameworks (MOFs). Specifically, a new rare earth nonanuclear carboxylate-based cluster was used as an 18-connected MBB to form gea-MOF-1. Why it matters: This work contributes to the advancement of solid-state materials design, which could have broad implications for energy and environmental sustainability in the region.
A KAUST research team led by Prof. Osman Bakr developed a novel antisolvent vapor-assisted crystallization (AVC) method to grow high-quality, crack-free MAPbX3 perovskite single crystals at room temperature. The resulting crystals exceeded 100 mm3 in volume and exhibited exceptionally low trap-state density (approximately 10^9 – 10^10 cm-3). The crystal quality is comparable to high-quality single crystal silicon, but grown at much lower temperatures. Why it matters: This breakthrough allows for more accurate characterization of perovskite photovoltaic properties and can accelerate improvements in solar cell efficiency.
