As part of SPECIFIC-IKC and the Sêr Solar research project, my research area focuses on solution processed photovoltaic materials and devices. My published work so far has focused on developing novel materials and processing methodologies to enable the production of low-cost flexible photovoltaics.

I am currently leading the creation of the Advanced Characterization of Devices Group through the SPARC-II project. The group utilizes frequency domain techniques such as Intesnity Modulated Photovoltage Spectroscopy (IMVS), or time resolved measurement such as Transient Photovoltage Decay and photo-CELIV to characterize carrier transport, recombination and mobility in photovoltaic devices, with a particular interest in quantifying loss mechanisms when increasing device size from lab scale to pilot scale, and in the characterization of degradation mechanisms.

I currently lead SPECIFIC's newest research activity on novel solution processable thermoelectric materials and devices and also lead a British Council funded Newton-Al Farabi partnership, working with a research group at the Institute of Physics and Technology, Almaty, Kazakhstan, to develop tandem silicon-perovskite solar cells.


I am currently undergraduate admissions tutor for Materials Enginering. Please get in touch if you want to study Materials by the beach!
