Hannah graduated with a BS in Materials Science and Engineering from Cornell University with a focus in Sustainable Energy Systems. Her work focuses on clarifying the role of the buried interface in perovskite solar cell device efficiency and stability. While she initially approached interfacial optimization through device fabrication projects, she built our cross-sectional atomic force microscopy setup and continues to investigate interfacial breakdown dynamics with this and a variety of PL techniques. Outside the lab, she remains deeply invested in the clean energy transition as both an outdoor enthusiast and mountaineer.
