Summary of Activities/Interests
Jeff is a fourth year doctoral student in the Chemical and Biomolecular Engineering Department at Notre Dame. He is originally from Grand Rapids, Michigan where he received his bachelor degree in Chemical Engineering from Calvin College in 2010 and performed research on using individual CdSe quantum dots as wide dynamic range fluorescent biosensors. Jeff's work in the Kamat lab has focused on improving Sb2S3 extremely thin absorber (ETA) solar cells by understanding the hole transfer mechanism in these devices. Currently, Jeff is exploring organo-metal lead halide perovskites for use in photovoltaics, studying alternative hole conductor materials and improving the understanding of these devices.
Title of Dissertation: Mesostructured Thin Film Solar Cells: Examining Hole Transfer Mechanisms and Device Stability
