Professor Yonghua Chen

Dr Yonghua Chen is currently a full professor at Institute of Advanced Materials at Nanjing Tech University. He has got the Young 1000 Talents, Jiangsu Specially-Appointed Professor, Jiangsu Distinguished Young Scholars projects, and Jiangsu Province six talent peak projects. He has been focusing on perovskite photovoltaic cells in view of its efficiency and stability by taking ionic liquids as the main research line.

The main representative results are as follows: 1) He has conceived and fabricated perovskite thin films based on environmentally-friendly ionic liquids instead of traditional commonly used toxic aprotic polar solvents, achieving highly efficient and stable perovskite solar cells. 2) He has proposed a new chemical control strategy for precursor solution, which stabilizes the layered perovskite framework and builds phase-pure layered perovskites. Highly efficient and stable two-dimensional layered perovskite photovoltaic cells were achieved. 3) A new method of ion channel reaction is proposed, stabilizing perovskite formation at room temperature and high humidity and achieving high efficiency and long-term stability.

In the last 5 years, as corresponding author, he has published 70 papers (including in Science, Nature Energy, Nature Photonics, Chem, Advanced Materials, Nano Letters, Angewandte Chemie International Edition, etc.).
