FUNSOM of Soochow University Published an Important Research Achievement in Science

Recently, a paper co-authored by Professor Wang Zhaokui from FUNSOM of Soochow University and Professor Yang Yang, from Westlake University and UCLA was published in the journal of Science. This is the second time that FUNSOM as a communications agency has published a paper in Science, one of the top journals in the world.

 

 

This paper mainly introduces the important achievements made by the research team of Professor Wang Zhaokui and Professor Yang Yang in the research on the surface passivation mechanism of perovskite solar cells. The study of the passivation mechanism of the titanium surface and the configuration design of the passivation molecules are an effective way to further improve the photoelectric conversion efficiency values of the perovskite solar cell. The formation of hydrogen bonds between N-H and I (iodine) helps C = O to combine with Pb defects, thereby maximizing the passivation effect of perovskite surface defects, which is the molecular structure of the surface passivation of perovskite solar cells the type design guides the direction.
