A Kookmin University analysis team has developed a technology for the scalable synthesis of extremely uniform perovskite quantum dots in collaboration with researchers from different establishments together with the Daegu Gyeongbuk Institute of Science and Technology (DGIST).
Kookmin University stated Tuesday that Kim Jae-hyuck, a grasp’s pupil in the college’s division of chemistry, performed a key position in the study as a co-first creator.
Kim is a member of the college’s analysis team, led by chemistry professor Kim Young-hoon. His team collaborated with one other Kookmin University analysis team led by chemistry professor Kim Hyung-min and a DGIST team led by power science and engineering professor Choi Jong-min.
The findings had been printed on July 3 in the worldwide journal ACS Energy Letters beneath the title, “Precursor Diffusion-Controlled Scalable Synthesis of Monodisperse Iodide Perovskite Quantum Dots for Photovoltaics.” The journal is printed by the American Chemical Society.
The paper was co-first authored by Kim Jae-hyuck and Dr. Kim Ji-geon of Kookmin University, together with Dr. Han Sang-hun of DGIST. The corresponding authors are professors Kim Hyung-min and Kim Young-hoon of Kookmin University and DGIST professor Choi Jong-min.

The college stated perovskite quantum dots have emerged as a promising materials for next-generation photo voltaic cells owing to their excellent optical and electrical properties.
However, typical synthesis strategies contain extraordinarily speedy response kinetics, making it more and more troublesome to take care of uniform particle measurement and high quality as manufacturing scales up.
As a outcome, the large-scale manufacturing of high-quality perovskite quantum dots and their software in high-efficiency photo voltaic cells have remained vital challenges.
To overcome these challenges, the analysis team developed a precursor diffusion-controlled scalable synthesis methodology that exactly regulates the diffusion charge of precursors, enabling the nucleation and crystal progress levels to be independently managed.
Using this method, the team efficiently synthesized extremely uniform perovskite quantum dots on a big scale and demonstrated an influence conversion effectivity (PCE) exceeding 15 p.c in photovoltaic gadgets fabricated from the large-scale-synthesized quantum dots, considerably enhancing the feasibility of industrial-scale manufacturing.
The college stated the scalable synthesis technology for perovskite quantum dots might enhance the efficiency of next-generation photo voltaic cells.
The newest publication additionally marks one other achievement for Kim Jae-hyuck. He beforehand printed a paper as the only real first creator in Nano Research in 2025 and has since printed one other paper in a number one worldwide journal in the sphere of power.
He has additionally demonstrated excellent analysis capabilities in supplies and power science, receiving an impressive paper presentation award from the Polymer Society of Korea.
