Research Interests

The Dou research group is interested in hybrid materials synthesis and processing for the next generation energy harvesting and optoelectronics devices. Both fundamental understanding of the materials structure-property relationships and the application in high performance energy-efficient devices are emphasized. Prior to joining the Davidson School of Chemical Engineering, Dr. Dou held research positions at UC Berkeley/Lawrence Berkeley National Laboratory/California Research Alliance by BASF, at UCLA, and at University of California, Santa Barbara.

Dr. Dou was part of a research team that set a certified world record of 10.6% power conversion efficiency for organic solar cells. He has given several invited talks and conference presentations, and has also been awarded six patents. Dr. Dou has more than 30 research publications with over 7000 citations.
