Emily Warren

Emily Warren is a Research Manager II at the National Renewable Energy Laboratory (NREL), specializing in Materials Science, Chemistry, and Nanoscience within Photovoltaics. Her research focuses on heteroepitaxy of III-V materials on silicon, nanoimprint lithography, and high-efficiency tandem solar cells.

• PhD in Chemical Engineering from California Institute of Technology
• Master of Engineering for Sustainable Development from University of Cambridge
• Bachelor of Chemical Engineering from Cornell University

Warren investigates nanoscale surface control in heteroepitaxial film nucleation and coalescence. Her work on three-terminal tandem solar cells with interdigitated back contacts simplifies large-area device scaling. She also explores TCAD simulation and photoelectrochemical systems for solar fuels.

Her 2025 publications include studies on GaAs/silicon heterostructures, methanol generation via CO₂ reduction, technoeconomic modeling of tandem modules, and exfoliation techniques for solar cell performance. These span Materials Science, Solar Energy, and Device Physics.

Warren collaborates with universities on photovoltaic research and mentors students, earning recognition for her training efforts. Her work at NREL includes prior projects on solar thermoelectric generators using the High Flux Solar Furnace.
