Prof. He from Southern University of Science and Technology gave a talk entitled ‘Efficient perovskite solar cells enabled by molecules coordination’ at the Faculty of Science and Technology on Jul. 18, 2023.  At the seminar, Prof He shared his latest research results in the field of solar cell. Prof. He introduced their designed molecules related to CzPA and their roles in efficient perovskite solar cells, especially the interaction between the phosphonic acid group and perovskite. Basing on the innovative design, Prof. He reported a novel molecule-extrusion process for efficient and high-stability perovskite solar cells.
