About

I joined Swansea in 2017 as Chemistry Engineering Steel Bridge Professor. My research interests are industry facing and relate to advanced materials and related manufacturing processes. Hence, we use fundamental chemical understanding of molecules and interfaces to understand and solve large-scale materials engineering and manufacturing issues.

We research in 3 main areas:

  • Renewable energy; particularly materials chemistry for solar cell manufacturing
  • Advanced steel technology; particularly decarbonisation of iron making and new product development
  • Water; particularly contaminant fate and selective water treatment

Areas Of Expertise

  • Synthetic and materials chemistry
  • Advanced devices such as photovoltaics (solar cells)
  • High temperature thermal chemistry
  • Steel manufacturing and value-added products
  • Surface chemistry and sorption processes
  • Water treatment
  • Manufacturing optimisation

Career Highlights

Teaching Interests

EG-290 Order and Disorder in Materials

Introduction to imperfections in crystals; point defects (impurities and vacancies), line defects (dislocations) and planar defects (interfaces and grain boundaries). Understanding of crystal growth and defects. The positive and negative effects of defects on different types of crystalline materials; and how understanding can lead to control.

Research

We design and synthesise bespoke molecules to study self-assembly approaches towards roll-to-roll (R2R) manufacturing of perovskite solar cells on flexible substrates. In this context, self-assembly can be defined as a process by which perovskite device sub-components adopt a desired device arrangement without external input.

Our group is designing and synthesising device sub-components to enable self-assembly and then to develop in situ metrology (e.g. spectroscopy, visualisation) to monitor the self-assembly and overall manufacturing progress. To date, we have identified limitations of toxic manufacturing solvents1,2and developed solvent-free self-assembly of perovskite onto metal oxide scaffolds leading to the development of inks based on benign solvents3. The resultant perovskite films also exhibit enhanced stability to humidity and air exposure. We are currently extending the self-assembly approach to Pb-free perovskites and to other device sub-components (e.g. substrates, charge carrying layers).
