Dr. Brianna Conrad is an Electrical Engineer and Postdoctoral Researcher in the Heat Transfer and Alternative Energy Systems (HTAES) Group of the Engineering Laboratory (EL) at the National Institute of Standards and Technology (NIST). She joined NIST in 2020 as part of a project on photovoltaic (PV) cell and module characterization. Her research includes the use of hyperspectral imaging of PV cell electro- and photoluminescence, spectral and intensity effects on the performance of solar cells, and the interpretation of PV measurement results. Detailed characterization and accurate interpretation is essential to understanding the physical processes within PV cells and guiding research and development along the most fruitful paths. Particular interests include multijunction solar cells, III-V semiconductors, novel materials and devices, and optical and interface effects within devices.
Dr. Conrad earned her bachelor’s degree in physics and electrical engineering from the Massachusetts Institute of Technology (2011), and her PhD in photovoltaic engineering from the University of New South Wales in Sydney, Australia. Her thesis work focused on the design, fabrication, and characterization and improvement of a GaAsP/SiGe tandem cell on a silicon substrate, with emphasis on optical properties and characterization methods. Prior to joining NIST, she was a postdoctoral researcher at the Czech Technical University in Prague, studying perovskites for PV applications and the effect of illumination intensity on silicon-based PV performance.
