Ph.D. (Kookmin University, South Korea)

B.Sc. (University of Indonesia)

Dr. Randi Azmi obtained his B.Sc. degree in condensed matter physics from University of Indonesia, graduating as the 1st rank student (2010–2014). He then completed his PhD in Applied Nano-Chemistry at Kookmin University, South Korea, graduating with Summa Cum Laude (2014–2020). Prior to joining CUHK-SZ, Dr. Azmi worked at Solar Center, King Abdullah University of Science and Technology (KAUST), Saudi Arabia, as a Postdoctoral Researcher and Research Scientist (2020–2024).

Dr. Azmi’s research group (Heterojunction Materials for Renewable Energy Lab“HEROLAB”) is interested in performing extensive research on high-efficiency organic and inorganic hybrid heterojunction thin-film-based single- and multi-junction solar cells. The group's objective is to develop next-generation solar cell technologies that are both efficient and stable. With this emphasis, his group approaches technological advancements from a variety of disciplines, covering fields from novel materials to device fabrication, involving process and material optimization, and evaluating solar cells in realistic working environments with the goal of advancing them to an industrial level.

Dr. Azmi has published more than 35 articles in top-tier journal and publishers such as AAAS, Springer Nature, Wiley, ACS, Cell Press, and RSC. He is also the first author of papers published in prestigious journals like Science and Nature. In 2022, he was honored with the ASEAN Young Scientist Award for his exceptional contributions to science, technology, and innovation.
