Dr Michael P. Nielsen is currently a Scientia Lecturer in the School of Photovoltaic and Renewable Energy Engineering working alongside Associate Professor N. J. Ekins-Daukes (https://research.unsw.edu.au/people/associate-professor-nj-ekins-daukes). 

He obtained his BEng in Engineering Physics (Nanoengineering) in 2011 from the University of Alberta in Edmonton, Alberta, Canada, followed by an MSc in Electrical Engineering (Photonics and Plasmas Specialization) in 2013 where he was supervised by Professor Abdul Elezzabi, also at the Unversity of Alberta. Dr. Nielsen graduated with a PhD in Physics in 2017 from Imperial College London where he studied semiconductor nanoplasmonics under Dr. Rupert Oulton and Professor Stefan Maier. After graduation, he continued at Imperial College London as a Research Associate studying nonlinear optics in plasmonic and nanophotonics systems and managing an ultrafast spectroscopy laser laboratory, before coming to UNSW as a postdoctoral fellow in May 2018. Starting January 2019, Michael was appointed a UNSW Scientia Lecturer.


My Research Activities

His research is focused on the use of ultrafast spectroscopic techniques for advanced characterization of novel photovoltaic materials. Such techniques include transient absorption spectroscopy (TAS), terahertz time-domain spectroscopy (THz-TDS), femtosecond stimulated Raman spectroscopy (FSRS), and ultrafast photocurrent spectroscopy (UPS). Other interests include hot carriers for photovoltaics, photodetection, and photochemistry, molecular photovoltaics focusing on singlet fission and triplet-triplet annihilation for up/down conversion, and optical characterisation techniques such as photoreflectance for new materials. Much of the group's research is focused on the III-V material platform for advanced third generation photovoltaic concepts, and space and concentrator PV systems. More details can be found on the group website https://www.qpvgroup.org/  .


My Research Supervision


Areas of supervision

PhD positions are currently available for students in the following topics:
