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 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 held a research conference on Synergistic Approaches in Solar Energy Conversion from February 25-27, bringing together KAUST researchers and international colleagues. The conference, organized by the KAUST Solar Center (KSC), focused on performance-limiting factors, emerging synergistic approaches, and methods to overcome current performance limits in solar energy. Yves Gnanou and Professor Iain McCulloch highlighted KAUST's commitment to solar energy research and the KSC's role in collaborative, applied solutions. Why it matters: The conference underscores KAUST's dedication to advancing solar energy technologies and fostering international collaboration to address regional and global energy challenges.
KAUST and K.A.CARE have partnered to study solar irradiation and atmospheric weather conditions in Saudi Arabia, leveraging K.A.CARE's Renewable Resources Atlas Project. The collaboration uses KAUST's Shaheen II supercomputer to simulate weather and atmospheric conditions from 2005-2018. The long-term goal is daily forecasting of weather and air quality across the Arabian Peninsula. Why it matters: This initiative will provide crucial data for renewable energy development and environmental monitoring in the region, supporting Saudi Arabia's sustainability goals.
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.
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.
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.
KAUST's Functional Nanomaterials Laboratory (FuNL), led by Prof. Osman Bakr, focuses on synthesizing nanomaterials with novel optical, electronic, and magnetic properties for solar cells and other devices. The lab's research centers on controlling the size and composition of nanoparticles to optimize light absorption across different wavelengths. Unlike silicon-based solar cells, nanoparticle-based solar cells can be processed at low temperatures and potentially integrated with roll-to-roll printing. Why it matters: This research could lead to more efficient and versatile solar energy solutions, including printable photovoltaic thin films for buildings and flexible electronics.
