With experience in the fundamentals of colloidal semiconductor nanocrystals, Brian Wieliczka joined NREL in 2019 to work with Joseph Luther to develop applications of these materials to address the need for renewable energy, particularly through quantum dot solar cells.

He received his bachelor's degree in chemistry from St. Olaf College in 2012, where he synthesized new organometallic complexes under the mentorship of Professor Gary Miessler. He then moved to Washington University in St. Louis to pursue a doctorate in chemistry under the direction of Professors William Buhro and Richard Loomis. There he developed the synthesis of CdSe/PbS core/shell nanocrystals and used optical spectroscopy and charge carrier calculations to characterize the nanocrystals’ optoelectronic properties.
