Iain McCulloch, director of the KAUST Solar Center, has been elected as a Fellow of the Royal Society. McCulloch's research focuses on high-performance organic semiconductor materials for applications such as transparent solar cells and sensors. The Royal Society, founded in 1660, is the UK's national science academy and a fellowship of eminent scientists. Why it matters: This recognition highlights KAUST's contributions to advanced materials research and its role in fostering scientific talent in the region.
Maryam Alsufyani, a KAUST Ph.D. student in the Solar Center under Professor Iain McCulloch, focuses her research on designing and preparing semiconductor organic polymers for solar cells and organic electrical devices. She received her master's degree in chemical science from KAUST in 2018 and her bachelor's in chemistry from Taibah University in Madinah in 2016. Alsufyani aims to complete post-doctoral research after her Ph.D. to educate and support future generations. Why it matters: This highlights KAUST's role in fostering Saudi talent in renewable energy research, a key area for the Kingdom's future economic diversification.
KAUST researchers studied quantum dot (QD) solar cells, finding that QD size significantly impacts electron injection efficiency. Using femtosecond broadband transient absorption spectroscopy, they examined charge transfer between QDs and phenyl-C61-butyric acid methyl ester (PCBM). They demonstrated that smaller QDs with a bandgap larger than 1 eV facilitate electron transfer to PCBM upon light absorption. Why it matters: This work provides insights into optimizing QD solar cell design by tuning electron injection through QD size, potentially leading to more efficient and low-cost photovoltaic technologies.
KAUST Discovery Professor Tao Wu's research focuses on oxide thin films and nanomaterials for applications in spintronics, nonvolatile memory, energy harvesting, and sensors. His group aims to develop oxide thin film heater structures by combining different materials at the unicell level to create new artificial materials. The main technical areas involve spintronics, electric field effect devices, and oxide solar cells, leveraging Saudi Arabia's abundant solar energy. Why it matters: This research could lead to next-generation electronic devices and solar cells using more stable and versatile oxide-based solutions, aligning with Saudi Arabia's renewable energy goals.
