Kim Jae-hyuk, a master’s student in the Department of Chemistry at the Graduate School of Kookmin University (President Jeong Seung-ryeol; Advisor: Professor Kim Younghoon), recently received the “Outstanding Paper Presentation Award” at the “2026 Spring General Meeting and Academic Conference of the Korean Society of Polymer Science and Engineering” in recognition of the creativity and excellence of his research.

Kim Jae-hyuk, a member of the Colloidal Energy Nanomaterials Laboratory, presented his research findings at the conference under the title “Gram-Scale Synthesis of Monodisperse Perovskite Quantum Dots via Precursor Diffusion Controlled by Ligand Coordination and Realization of High-Performance Solar Cells.”

Perovskite quantum dots possess excellent optical properties, such as outstanding color purity and high absorption coefficients, and are attracting attention as next-generation optoelectronic materials. However, their commercialization has been limited due to the difficulty of achieving highly homogeneous mass production. Kim Jae-hyuk solved this problem by precisely controlling nucleation through the regulation of precursor diffusion, demonstrating the feasibility of manufacturing monodisperse quantum dots on a gram scale.

Notably, this study succeeded in the direct, large-scale “one-pot” synthesis of mixed-cation-composition quantum dots—a task previously considered a major challenge—and demonstrated that quantum dots synthesized in this manner can be used to create high-performance solar cells. This achievement is significant in that it broadens the possibilities for the mass production and practical application of perovskite quantum dots.

Student Kim Jae-hyuk said, “I believe this award is thanks to my advisor and the colleagues with whom I conducted this research,” adding, “I will continue to strive to produce high-quality research that benefits many researchers.”
