Photovoltaic and Renewable Energy Engineering

Bio:?Fiacre Rougieux has a PhD from the Australian National University in the field of photovoltaics and semiconductor materials. Between 2012 and 2018, he was an ARENA Post-doctoral Fellowand subsequently an ARC DECRA fellow at the ANU where he developed high-efficiency and low-cost solar cell concepts including efficiency records and successfully developed a wide range of processes to remove defects in solar cells and improve their efficiency.

Fiacre is currently a Senior Lecturer at UNSW. He has published and co-authored more than 100 papers. His research interests include advanced solar cell processes, system design and solar cell, module and system degradation.

The goal of our team is to engineer the materials, device and systems required to accelerate our transition to a decarbonised and circular economy. Our work lies at the intersection of materials science, semiconductor physics, solar cells, modules and systems. As a result of intensified research activities, our?international research network has grown significantly and we?collaborate with many the leading photovoltaics laboratories across the globe, including student research exchanges. We also welcome international and domestic visitors in our group.

Some of our recent research successes include the development of advanced characterisation techniques to measure dilute defects in ultra-high efficiency solar cells, the successful development of novel defect imaging techniques for defects in semiconductors, the creation of advanced defect analysis capability (Deep Level Transient Spectroscopy) at UNSW and the development of new recombination analysis theoretical framework and advanced measurement methods to link strain and recombination activity in photovoltaic?materials.

We are currently looking for students enthusiastic about producing technologies to diagnose and mitigate underperformance of photovoltaic cells, modules and systems.

For a detailed description of all our topics please email us directly.

We also welcome students to suggest their own research project.
