Eric Colegrove, staff scientist at NREL with more than 10 years of experience in cadmium telluride (CdTe)-based solar photovoltaics (PV) research and development was one of the keynote invited speakers at the recent PVSAT17 & SuperSolar Conference, held at IoP in London at the end of June 2023. As part of his visit to the UK Eric presented an extended version of his keynote to researchers at Loughborough University. Eric has kindly agreed to make his talk available to view for the benefit of those unable to attend PVSAT17.
The lecture entitled “Arsenic Doping for High Performance CdTe Based Photovoltaics: Progress and Challenges” is available to view here
Eric Colegrove‘s graduate work focused on arsenic doping of single crystal CdTe thin-films deposited by molecular beam epitaxy (MBE). His postdoc appointment at NREL continued this work, expanding from single crystal model systems to large grain polycrystalline material and additional group V dopants including phosphorus and antimony. Recently, as a staff scientist, his research focus has shifted to challenges associated with implementing group V doping in polycrystalline thin-film devices while supporting various other inter-related research efforts to improve the performance and stability of CdTe based PV materials.
