Andrew J. Ferguson - Research Scientist
Andrew Ferguson received his Ph.D. in Physical Chemistry from Imperial College under the supervision of Prof. Tim Jones in the Centre for Electronic Materials & Devices (CEMD). His research focused on understanding the effect of polycrystalline organic semiconductor film growth conditions on their optoelectronic properties. After graduation, he began work as a postdoctoral research assistant at the CEMD, where he investiged the effect of growth conditions, and hence device structure, on small-molecule excitonic solar cells.
Based on his interest in organic photovoltaics (OPV), Dr. Ferguson took the opportunity to join Dr. Garry Rumbles at NREL, starting a postdoctoral research position at NREL in March of 2006. His primary research interest was to develop an understanding of the fates of excitons and carriers in OPV material systems such as conjugated-polymer:fullerene blends using time-resolved microwave conductivity (TRMC) and time-resolved and steady-state photoluminescence spectroscopy.
Dr. Ferguson is now a research scientist collaborating with Dr. Justin Johnson on a project using spectroscopic tools to investigate the factors affecting the formation of triplet states in light-harvesting materials and their potential role in OPV devices. He is also involved in a project to study the formation and decay of excited states in novel molecular donor-acceptor assemblies using TRMC in conjunction with time-resolved and steady-state spectroscopic techniques.
