Osman M. Bakr's group in the KAUST Catalysis Facility has designed a low-temperature method that can be useful for making improved single crystal perovskites. The team said that novel perovskites have positive and negative ions in the same plan as the natural perovskite calcium titanate (CaTiO3). Lead halide perovskites, having lead ions as well as halide ions, such as chlorine and iodine in the perovskite mix, are drawing attention for optoelectronic applications.
The crystals have previously been created using high temperatures, however these have created many challenges. Now, the KAUST team has developed a new approach, enabling better crystals to form.
