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.
NOMADD, a KAUST startup, offers a waterless and remotely operated system to clean solar panels, addressing the challenge of dust accumulation which can reduce solar panel efficiency by 0.4-0.8% daily. KAUST recently signed its first royalty-bearing license agreement for the NOMADD system. The fifth version of the NOMADD system is 70% lighter and uses less than half the power of previous versions, while also being cheaper to manufacture. Why it matters: This technology is crucial for Saudi Arabia to achieve its ambitious goal of generating a third of its electricity from solar power by 2032, amidst the challenges posed by desert dust.
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 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.
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.
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 at KAUST, Fraunhofer ISE, and University of Freiburg developed a method using 1,3-diaminopropane dihydroiodide (PDAI) to treat the perovskite surface of perovskite silicon tandem solar cells. The treated solar cells achieved a conversion efficiency of 33.1% and an open-circuit voltage of 2.01 volts. The devices maintained performance at over 40°C for over 1500 hours along the Saudi coast. Why it matters: This innovation overcomes challenges in surface passivation of textured perovskite cells, paving the way for more efficient and stable solar energy solutions suitable for deployment in hot climates.
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.
