Dr Alison Ciesla

Engineering
Photovoltaic and Renewable Energy Engineering

Alison is a Scientia lecturer in the School of Photovoltaics and Renewable Energy Engineering. She completed her PhD in Photovoltaics (PV) in 2017 focusing on reducing recombination and mitigating LID. She is inventor >10 related patents and has published >50 research papers. Several of her patents for which she is lead inventor have been commercialised. She was part of the team that commercialised Suntech’s laser doped and plated PLUTO cell technology. She has extensive experience in managing technology transfer and industry collaborations with many larger silicon, wafer, cell and module manufacturers from Asia, Europe and America, and spent a month with the materials research team at Oxford University in 2017.

She is currently co-leading a project focused on manipulating hydrogen for trapping in silicon crystal defects for improved passivation. She also investigates PV module degradation and reliability of commercial silicon modules. The ultimate goal of Alison's research is to maximise the long-term power output of commercial silicon solar cells while reducing costs by enabling use of cheaper silicon wafer sources and improving reliability of modules.
