At NREL Since: 
2006

Andrew Ferguson received his Ph.D. in Physical Chemistry from Imperial College, researching the photophysical properties of molecular organic semiconductors under the supervision of Prof. Tim Jones in the Centre for Electronic Materials and Devices (CEMD).

After his graduate studies Dr. Ferguson joined Garry Rumbles' group at NREL as a postdoctoral researcher, investigating the fate of excitons and carriers in organic photovoltaic (OPV) material systems, such as conjugated-polymer:fullerene blends, using time-resolved microwave conductivity (TRMC) as well as time-resolved and steady-state photoluminescence spectroscopy.

Research Interests

Dr. Ferguson is now a research scientist in the Chemical and Materials Science Center and is actively involved in the investigation of novel mechanisms for third-generation solar photoconversion schemes. He is a principal investigator for an Office of Energy Efficiency and Renewable Energy, Next Generation Photovoltaics II Project studying frequency upconversion phenomena to enhance solar conversion efficiencies, and is a key member in a research team investigating factors influencing singlet fission and the interaction of plasmon-active substrates with excited states in model organic semiconductor systems.  Dr. Ferguson is also interested in understanding excited-state dynamics in blends of conjugated polymers and single-walled carbon nanotubes, and the potential application of such system as light-harvesting active layers for OPVs.  He is currently leading, along with Dr. Jeffrey Blackburn, a Laboratory Directed Research & Development (LDRD) project focused on understanding and controlling the factors that affect the thermal and electrical transport properties of organic semiconductor thin films.
