Professor Thuc-Quyen Nguyen is a world-leading scientist in organic photovoltaics (OPVs), specializing in carbon-based devices that convert sunlight into electricity. Her expertise spans chemistry, materials science, engineering, and physics—a rare and powerful combination in OPV research. After earning her PhD in Physical Chemistry and completing a postdoc in molecular electronics at Columbia University, she shifted her focus to OPVs in 2004. Her pioneering work has revolutionized the field, particularly in developing solution-processed molecular organic semiconductors as a superior alternative to polymers, achieving breakthroughs in efficiency and reproducibility.
Nguyen’s innovations extend beyond materials. She developed advanced scanning probe microscopy techniques to analyze OPV structures at the nanoscale, creating tools now widely used in industries from batteries to semiconductors. Her team also introduced ternary blends and Hansen solubility parameters to optimize OPV performance, and discovered how additives like alkyl thiols could double device efficiency. These contributions have set new standards for OPV research, enabling power conversion efficiencies exceeding 20% and paving the way for commercialization.
A dedicated educator, Nguyen has mentored 155 students and researchers from 22 countries, emphasizing critical thinking, problem-solving, and real-world skills. She has also supported 25 young faculty members, particularly women and scientists from developing nations, and encouraged gender equity in academic conferences. Her courses prepare students for careers in sustainable energy, reflecting her commitment to addressing the climate crisis through education.
Nguyen’s transformative research, combined with her efforts in education, diversity, and mentorship, makes her an outstanding candidate for the Wilhelm Exner Medal.
