PDRA in condensed matter physics


I am a post doctoral researcher working in the Physics Department. I am interested semiconductor devices for optoelectronic and nuclear applications. Currently I am researching perovskite solar cells in the Photovoltaic and Optoelectronic Device Group within condensed matter physics. Perovskites are highly tuneable, intrinsically defect tolerant semiconductors with huge potential to reduce costs and increase the efficiency of key devices such as solar cells, LEDs and detectors. Low-cost perovskite solar cells have achieved equivalent efficiencies to traditional Si cells, but their stability still lags Si by an order of magnitude. I am investigating the stability of perovskite solar cells under accelerated aging conditions compared to real-world testing to generate methods to improve stability from years in the field to decades.
