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 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.
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.
KAUST Professor Derya Baran and her team at startup iyris have developed transparent solar panels that can turn windows into a source of renewable energy. The technology allows buildings to generate their own electricity, aligning with Saudi Vision 2030's goals for sustainable energy. iyris' first customer is the Red Sea Farm, another KAUST-based business, which aims to use the windows to improve plant growth and crop yield. Why it matters: This innovation could significantly reduce reliance on fossil fuels and promote sustainable urban development in the region, where cooling demands drive high electricity consumption.
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 hosted the Solar Future 2015 Symposium, gathering experts from academia and industry to discuss advancements in solar energy conversion. The symposium, organized by the KAUST Solar and Photovoltaics Engineering Research Center (SPERC), featured keynote presentations, plenary talks, and poster sessions. Discussions covered emerging and mature technologies aimed at achieving high efficiency and low cost in solar energy. Why it matters: The event highlights KAUST's role in fostering innovation and collaboration in renewable energy, aligning with Saudi Arabia's broader sustainability goals.
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.
