Chemical Engineering

As a graduate student in Hugh Hillhouse’s research group, Yuhuan is investigating bismuth rudorffites, a promising new material for the top cell in solution-processed tandem perovskites. These lead-free wide bandgap semiconductors could potentially serve as a high-performance alternative to the lead-based materials in hybrid perovskite solar cells currently used to increase the power conversion efficiency of solar cells while lowering their overall cost. A deeper understanding of bismuth rudorffites could enable the development of low-cost tandem solar cells from non-toxic elements. Yuhuan holds a B.S. in Materials Science and Engineering from Tianjin University and a M.S. in Materials Science and Engineering from the University of Washington.
