KAUST researchers have found that dust clouds in the Arabian Peninsula are three times larger than previously estimated by current models. The study, published in the Journal of Geophysical Research: Atmospheres, uses refined mathematical models and data collected since 2012 to analyze the impact of coarse dust particles. The updated model indicates that larger particles contribute to over 80% of dust mass on land, leading to significant efficiency loss for solar technology, estimated at 15-45% depending on location. Why it matters: Accurate dust modeling is crucial for the strategic deployment and maintenance of solar technology, supporting Saudi Arabia's sustainable economy goals.
KAUST researchers have fabricated and tested high-efficiency perovskite-silicon tandem solar cells optimized for hot climates. The tandem device is more stable than conventional perovskite cells and optimized for industry use. Outdoor testing at KAUST confirmed performance improvements, indicating bromide-lean perovskite top cells with narrower bandgaps are ideal. Why it matters: The research demonstrates the viability of tandem silicon-perovskite cells in harsh environments, paving the way for more efficient solar technology in the region and globally.
KAUST and King Abdulaziz University (KAU) have signed a memorandum of understanding (MoU) to collaborate and fund scientific research. The collaboration will focus on areas including cancer research, energy harvesting and storage, solar technology, renewable energy, and desert agriculture. The MoU was signed by Donal Bradley, KAUST VP for Research, and Yusuf Al Turki, KAU VP for Graduate Studies and Scientific Research. Why it matters: This partnership between two leading Saudi universities will help advance research and development in areas critical to Saudi Vision 2030.
