Solution-phase crystallization of molecules is a critical process across a broad range of industries, from pharmaceutical manufacturing to food processing. Because crystallization outcomes, including crystal morphology, orientation and structure, can significantly impact overall material properties, the ability to control this process is critical. Our laboratory is exploring the use of nanoconfinement to dictate crystallization outcomes in hybrid and organic systems for solar energy harvesting applications. My talk will focus using nanoconfinement as a strategy to control the crystallization of metal-halide perovskites and organic semiconductors for use in solution-processable organic photovoltaics.
Professor Stephanie S. Lee received her B.S. in Chemical Engineering from the Massachusetts Institute of Technology in 2007, and her M.A. in Chemical Engineering and Ph.D. in Chemical Engineering and Materials Science from Princeton University in 2009 and 2012, respectively. After completing an Academic Diversity and Postdoctoral Transition Fellowship at NYU, Professor Lee established the Hybrid Electronics Laboratory at Stevens Institute of Technology in Hoboken, NJ in 2014. Her current research projects include the nanoconfined crystallization of metal-halide perovskites to improve their stability in solution-processed solar cells, templating the growth of vertical organic semiconductor wires, and colloidal assembly for photonic crystal applications. Professor Lee received an NSF grant in 2016 to develop continuous processing methods for organic solar cells that afford control over the crystallization and phase separation of semiconducting polymer-small molecule composites.
