Christopher Petoukhoff is currently a KAUST Global Postdoctoral Fellow in the KAUST Solar Center, within the Ultrafast Dynamics Group. He received his PhD in 2017 from Rutgers University in Materials Science and Engineering, where he was awarded a Corning, Inc. fellowship, an NSF-IGERT traineeship, and an NSF-EAPSI – JSPS Summer fellowship. He transitioned to Okinawa Institute of Science and Technology (OIST) as a postdoc in 2017 to undertake research on ultrafast spectroscopy of solar energy materials. Christopher joined KAUST in 2022 to pursue his research interests in predicting, understanding, and mitigating losses in organic and perovskite solar cells. He combines time-resolved and steady-state optical spectroscopies with optoelectronic simulations and morphological characterization to understand and predict performance and stability losses. He has been working towards mitigating these losses using nanophotonic structures, nanomaterials, and interfacial energy level alignment.
