KAUST researchers developed Aqua-Fi, a system for underwater wireless communication using lasers and off-the-shelf components. The system uses a Raspberry Pi as a modem to convert Wi-Fi signals to optical signals, enabling bi-directional communication. Using blue and green lasers, they achieved 2.11 megabits per second over 20 meters, compliant with IEEE 802.11 standards. Why it matters: This innovation could significantly improve underwater data transmission, benefiting applications such as environmental monitoring, underwater exploration, and communication with underwater devices.
MIT Technology Review Arabia recognized two KAUST researchers in its annual Innovators Under 35 MENA Award. Yuxiang Liu developed Sun-Fi, an optical wireless communication network for smart cities that transmits data through window glass using modulated sunlight. Balsam Alkouz created a system for coordinating drone swarms to deliver supplies and deploy communications in disaster zones. Why it matters: The awards highlight KAUST's role in fostering innovative research aligned with Saudi Vision 2030 and developing cutting-edge technology for smart cities and crisis response.
The KAUST Solar Future 2014 meeting was held on the university's campus from November 7-11, hosted by the Solar & Photovoltaics Engineering Research Center (SPERC). Over 30 speakers from KAUST and international universities discussed current and future advances in solar and photovoltaic technologies. The meeting facilitated interactions between visiting professors, KAUST faculty, and students, with poster sessions allowing students to present their work. Why it matters: Such events promote KAUST's mission to become a leading institution in renewable energy science and engineering and attract new talent to the university.
KAUST hosted the Emerging Concepts and Materials in Solar Energy Conversion research conference from October 31 to November 2. The conference gathered scientists to discuss solar energy research, including perovskite solar cells, quantum dot solar cells, and photocatalysis. Rawabi Holding's chairman expressed pride in KAUST's solar research and its potential to address global challenges. Why it matters: By bringing together global experts and fostering discussions on innovative solar technologies, KAUST is contributing to advancements in renewable energy and sustainable solutions for the region.
KAUST researchers have developed solar panels with 4D-printed legs that readjust their position to track the sun's movement without consuming electrical energy. The design uses smart materials that contract when exposed to sunlight, tilting the panel towards the sun. A multidisciplinary team of interns collaborated on the project, integrating physics, electrical engineering, and mechanical engineering expertise. Why it matters: This low-cost, energy-efficient solar-tracking technology could significantly increase the energy output of solar cells, offering a viable renewable energy solution for the region and beyond.
KAUST researchers found that inserting a magnesium fluoride layer in perovskite–silicon tandem solar cells can stall charge recombination and enhance performance. The magnesium fluoride interlayer effectively promoted electron extraction from the perovskite active layer and reduced charge recombination at the interface. The resulting tandem solar cell achieved a stabilized power conversion efficiency of 29.1%. Why it matters: Improving the efficiency of solar cells is critical for expanding renewable energy capacity in Saudi Arabia and worldwide.
KAUST and the Future Investment Initiative (FII) Institute signed an MoU on January 27 to collaborate on research and facilitate access to scientific knowledge. The agreement was signed by KAUST President Tony Chan and FII Institute CEO Richard Attias at the fourth edition of the FII in Riyadh. The partnership aims to contribute to international development and welfare through actionable technological progress. Why it matters: This MoU signifies KAUST's commitment to translating research into tangible solutions for global challenges, aligning with Saudi Arabia's broader vision for innovation and development.
