Dong Authors Article on Perovskite Solar Cells

Professor and the Emma K. and Carl R. N. Malmstrom Endowed Chair in Physics Lifeng Dong has co-authored a scientific article, “Additive Engineering to Improve the Efficiency and Stability of Inverted Planar Perovskite Solar Cells,” published in Journal of Materials Chemistry C.

In this collaborative project with researchers at Qingdao University of Science and Technology in China and Chinese Academy of Sciences, a formamidine acetate salt additive engineering strategy is proposed to optimize both the film morphology and crystalline quality to improve both efficiency and stability of solar cells. This work provides a very easy and repeatable approach to get compact high-quality perovskite film, thus suitable for high performance perovskite solar cells.

Dong currently works with his collaborators and undergraduate students to design, synthesize, fabricate, and characterize nanoscale materials and devices — including solar cells, fuel cells, supercapacitors, and lithium batteries — for energy conversion and storage, as well as water purification and desalination.
