Aaron R. Arehart's research focuses on characterizing electrical and optical defects in thin-film semiconductor materials used for solar cells, including CIGS (copper indium gallium selenide), CdTe (cadmium telluride), and related compounds, as well as GaN-based transistors. His work aims to understand how material defects and processing steps affect solar cell voltage losses, reliability, and overall device performance. This research is largely experimental, combining device fabrication with electrical measurement techniques like capacitance-based defect spectroscopy.
