KAUST has launched a Center of Excellence (CoE) for Renewable Energy and Storage Technologies, chaired by Professor Husam Alshareef, to develop and deploy innovative renewable energy and storage technologies. The center will focus on homegrown technologies invented at KAUST and aims to attract investments, partnerships, and market interest for commercial adoption. Research will focus on prototyping and scaling technologies across six key themes including advanced photovoltaics and new battery chemistries. Why it matters: This initiative aligns with Saudi Vision 2030, supporting the Kingdom's climate goals and transition to sustainable energy while creating jobs and enhancing energy security.
KAUST researchers have achieved a breakthrough by passing the damp-heat test for perovskite solar cells (PSCs), a rigorous assessment of their ability to withstand prolonged exposure to high humidity and temperatures. The team engineered 2D-perovskite passivation layers that block moisture and enhance power conversion efficiencies. The successful test, which requires maintaining 95% of initial performance after 1,000 hours at 85% humidity and 85 degrees Celsius, marks a significant step toward commercialization. Why it matters: This advancement addresses a critical weakness of PSCs and brings the technology closer to competing with silicon solar cells in terms of stability and longevity, crucial for widespread adoption of renewable energy.
Researchers from KAUST and University of Toronto have created a two-sided perovskite/silicon tandem solar cell that exceeds the performance limits for tandem configurations. The bifacial design captures both direct sunlight and light reflected from the ground (albedo). Outdoor testing demonstrated efficiencies beyond commercial silicon solar panels. Why it matters: This innovation promises ultra-high power generation at affordable costs, potentially revolutionizing the photovoltaics market in the region and globally.
Jean M. J. Fréchet, retired KAUST senior vice president, has been awarded the King Faisal Prize in Chemistry for his pioneering work in dendrimers, photoresists, and organic photovoltaics. His work has contributed to advancements in biotherapeutics, organic electronics, materials, and microfluidics. Fréchet is the 10th most cited chemist globally, with over 900 publications and 200 patents. Why it matters: The recognition highlights KAUST's impact on global scientific advancement and underscores the importance of investing in basic research with broad applications.
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.
KAUST Catalysis Center (KCC) and KAUST Solar Center (KSC) partnered with Nigerian startup Newdigit Technologies to develop their "Just Add Water" pilot. The project aims to use electrolysis powered by photovoltaics to split water into hydrogen (for cooking) and oxygen. The hydrogen produced can be utilized as a clean-burning gas for cooking, while the fuel cell generates electricity and produces clean drinking water. Why it matters: This collaboration highlights KAUST's role in fostering sustainable energy solutions for developing nations and addressing critical challenges like energy access and indoor air quality.
KAUST researcher Erkan Aydin is focusing his research on space-grade photovoltaics, driven by the increasing demand for low-cost solar cells due to the boom in space travel. Aydin notes that existing high-performance photovoltaics are too expensive and cannot meet the projected demand from mega-satellite constellations. He believes perovskite-tandem solar cells offer a cheaper and more scalable alternative, with the main challenge being stabilizing the cells against space extremes. Why it matters: This research aims to address a critical need in the rapidly expanding space industry, potentially positioning KAUST as a leader in developing cost-effective and scalable solar solutions for space applications.
KAUST and ARMOR, a global technology company, have collaborated to create new solar-powered outdoor seating featuring flexible, lightweight, and semi-transparent solar technologies. The installation of the smart solar street furniture has been completed on KAUST campus in Saudi Arabia. The ASCA film used draws on technology co-developed by researchers at the KAUST Solar Center, using printed semiconducting inks on plastic film. Why it matters: This project demonstrates the potential for integrating KAUST's solar research into commercially viable applications and strengthens ARMOR's presence in the MENA region.
