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.
This study introduces a reinforcement learning (RL) framework using Proximal Policy Optimization (PPO) and Soft Actor-Critic (SAC) to optimize the cleaning schedules of photovoltaic panels in arid regions. Applied to a case study in Abu Dhabi, the PPO-based framework demonstrated up to 13% cost savings compared to simulation optimization methods by dynamically adjusting cleaning intervals based on environmental conditions. The research highlights the potential of RL in enhancing the efficiency and reducing the operational costs of solar power generation.
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 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's Image and Video Understanding Lab is developing machine learning algorithms for computer vision and object tracking, with applications in video content search and UAV navigation. Their algorithms can detect specific activities in videos, helping platforms detect unwanted content and deliver relevant ads. The object tracking algorithm is also used to empower UAVs, enabling them to follow objects autonomously. Why it matters: This research enhances video content analysis and UAV capabilities, positioning KAUST as a leader in computer vision and AI applications within the region.
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 and KACST have developed a composite material that enhances solar cell performance by absorbing air moisture at night and releasing it during the day. When applied to solar cells in Saudi Arabia, the material increased power output by 12.9% and extended cell lifespan by over 200%. The passive cooling technology also reduced electricity generation costs by 18%. Why it matters: This innovation addresses a key challenge in solar energy adoption in hot climates, potentially making solar power more efficient and cost-effective in the region.
