Alex Bothwell

Postdoctoral Researcher-Chemistry

Alexandra Bothwell joined in NREL in early 2021 as a postdoctoral researcher. Her research focuses on the electro-optical properties of thin-film photovoltaic (PV) devices through spectroscopic measurements, with a primary focus on understanding and mitigating efficiency-limiting loss mechanisms in these devices. 
She obtained her bachelor's degree in physics from Hamilton College and doctorate from Colorado State University. Her doctoral work focused on fabrication and characterization-guided improvement of the voltage deficit in thin cadmium telluride (CdTe)-based PV devices.
