At the 22^nd Y. Z. Hsu Science Awards, Professor Chi-Ching Kuo from the Department of Molecular Science and Engineering, National Taipei University of Technology, will be honored with the "Y. Z. Hsu Science Paper Award" in the Optoelectronics category. The award ceremony will be held on October 17^th, 2024.

Award-winning Paper: " Synergistic Effect of Cation Composition Engineering of Hybrid Cs1−xFAxPbBr3 Nanocrystals for Self-Healing Electronics Application "

Dr. Kuo's research addresses global environmental changes by developing novel self-healing polymer materials designed for green and sustainable applications. These polymers automatically repair structural damage and mimic human healing processes, effectively reducing resource consumption. Additionally, Dr. Kuo has pioneered the integration of self-healing polymers with optoelectronic materials, such as perovskites, successfully applying self-healing materials to optoelectronic devices and setting a new standard for Taiwan’s advancements in this field.

Dr. Kuo indicates that while traditional silicon solar cells reach 30% power conversion efficiency (PCE), perovskite optoelectronic materials with efficiencies currently approaching 20%, possess excellence in brightness and optoelectronic properties, and demonstrate greater potential in the optoelectronics industry. However, perovskites encounter two primary challenges: susceptibility to water and oxygen exposure causing degradation, and the potential for lead leakage, which poses environmental contamination risks. To address these issues, Dr. Kuo encapsulated perovskites with self-healing polymers to ensure water and oxygen isolation and prevent lead leakage simultaneously. Moreover, he developed a novel synthesis technique for producing high-purity materials, further boosting device efficiency. These techniques have potential applications in display backlighting, optical memory, and nanogenerators.
