Jun Peng Professor

Dr. Peng received his PhD from The Australian National University (ANU) in 2018. He was then employed as a postdoc by the ANU solar group; and in 2020, he was awarded a 2-year Australian Centre for Advanced Photovoltaics (ACAP) fellowship to continue his research at ANU as a research fellow. In 2022, Dr. Peng joined the Institute of Functional Nano and Soft Materials (FUNSOM) of Soochow University as a principal investigator.

Research Interests

Dr. Peng focuses on the development of high-performance perovskite solar cells, perovskite-silicon tandems and silicon solar cells. He achieved three certified steady-state efficiency records for perovskite solar cells with an active area of more than 1cm2, including:
1. Achieved two certified steady-state efficiencies of 21.6% and 22.6% [by CSIRO] for 1cm2 perovskite solar cells in 2019 [note that these two certified efficiencies were recorded in the Solar Cell Efficiency Tables (Versions 55-59)];
2. Collaborated with EPFL and achieved a steady-state efficiency of 21.52% [aperture area ~26.02 cm2, certified by NPVM] for perovskite cell mini modules in 2022.

Research Experience and Accomplishments

He published more than 60 peer-reviewed papers (received a total citation of more than 4100 times, h-index 33, https://scholar.google.com/citations?user=bLq6CN8AAAAJ&hl=en) in Nature (1#, first-author), Science (1#, first-author), Nature Energy, Nature Electronics, Science Advances, Joule, Energy & Environmental Science, Advanced Energy Materials, Advanced Functional Materials etc. Besides, he has one Chinese patent and applied for one Australian patent and one PCT patent.
