YunHui (Lisa) Lin joined NREL in 2019 as a director’s postdoctoral fellow under the mentorship of Justin Johnson. Her current research focuses on interfacial energy and charge transfer reactions in low-dimensional perovskite materials. She is also active in NREL’s Postdoc, Graduate Student, and Intern Employee Resource Group as a professional development officer. Prior to joining NREL, Lin received a doctorate in Electrical Engineering and Materials Science from Princeton University, where she was advised by Professor Barry Rand. In her doctoral research, she investigated donor/acceptor charge transfer states in singlet fission organic solar cells and developed a novel solid-state organic intermediate band solar cell using triplet-triplet annihilation upconversion. Lin enjoys working at the intersection of novel materials design and synthesis, spectroscopy, and application engineering.
