Printed Photovoltaics: Scale-Up and Processing Research Team

Dr Becky Bolton – Research Assistant

Becky is a research assistant in Professor Watson’s sheet-to-sheet printed solar cells group. Her key area of research is the upscaling and optimisation of large area, screen printed, perovskite solar modules.   

Becky has a doctorate and bachelors degree in Materials Science and Engineering, both completed at Swansea University. Her area of expertise was originally in electrochemistry and the inhibition of corrosion on strip steel. Her EngD, sponsored by Tata Steel, investigated the delamination resistance of organic films from novel physical vapour deposited Zn-Mg coatings.

Awards: Sidney Gilchrist Thomas Prize in Metallurgy (for best Materials Engineering student in Level 3) and the Institute of Materials, Minerals and Mining Prize (for best overall performance in Materials Engineering).

Areas of Interest

  • Large-scale film deposition
  • Screen printing 
  • Curing techniques
  • Electrochemistry 
  • Material characterisation
  • Laboratory HSE compliance

Simone Meroni is a researcher in Professor Trystan Watson’s PV group. All his formation and professional development is focused on materials and thin films.   

Simone’s first job was in a painting company which sparked his passion for thin films and coatings. He completed a Bachelors in chemistry of materials, where he published on thin film Mn oxides for gas sensors, in Italy. Simone’s Masters was completed in Germany, where he published on quantum dots sensitized solar cells. Simone Joined SPECIFIC in 2015. Here, he started working on perovskite solar cells and upscaling. Some important publications during these years include: the robotic mesh deposition technique and the scribing method for module manufacture. Currently, his activity focuses on the up-scaling of perovskite solar cells via printing techniques. Perovskite solar modules have been developed by Simone, including over 200 cm2 active area fully printable modules with carbon as top electrode.

Areas of Interest

  • Halide perovskites 
  • Printing and coating techniques, especially screen-printing, bar/blade coating and inkjet 
  • Thin-film devices
  • Solar module characterization 
  • Stability measurements

Dr Ershad Parvazian – Postdoctoral Research Assistant

Ershad joined Swansea University in the Autumn of 2020 as a postdoctoral research assistant. Currently, he is working in R2R team at SPECIFIC centre.

Ershad’s main activity here is developing printable perovskite devices with increased stability. He also works on translate any developments at slot-die coating level to roll to roll level. Ershad started experimental research on third generation of solar cells when he was a MSc student, by making DSSCs. After two years of study on dye sensitized solar cells, Ershad changed his field to printed perovskite devices and then focused on that for four years during his PhD period.

Areas of Interest

  • Printed photovoltaics 
  • R2R coating process 
  • Perovskite solar cells
  • Green solvents

Dimitrios took a degree in Physics and carried out a doctorate in Chemical Engineering at University of Patras in Greece. Then, he moved to Swansea to join Specific as a post-doctoral researcher.

During his PhD, Dimitrios investigated the use of innovative materials in 3rd generation photovoltaics (dye sensitised solar cells, solid state solar cells, perovskite solar cells) for optimizing the process of conversion solar energy into electricity. He also studied the use of alternative materials in photoelectrochemical cells for hydrogen production.

As a post-doctoral researcher, his research is focused in optimizing the properties and the deposition methods of the different materials of fully printable carbon-based perovskite solar cells and modules, in order to enhance devices efficiency and stability.

Areas of Interest

  • Fabrication and study of fully printable carbon-based perovskite solar cells
  • Deposition technologies for 3rd generation photovoltaics
  • Materials characterisation
  • Kelvin Probe measurements

Carys Worsley – PhD Student

Carys looking at new solvent

Carys is a PhD student in Professor Watson’s research group. Funded by the SUNRISE project, she works on printed mesoscopic carbon perovskite solar cells (CPSCs).

Thus far her work has focussed on examining and optimising alternative green solvent systems for CPSCs, as well as exploring potential additives for the performance enhancement of stable AVA0.03MAPbI3 devices. She has experience in a variety of testing and characterisation techniques, including cross sectional infiltration analysis, X-ray diffraction, UV-vis spectroscopy, External Quantum Efficiency measurements and contact angle testing.

Before starting her PhD Carys completed a masters’ degree (MChem) at the University of Bath, where she helped work on developing liquid crystal templates for producing ultrathin metal nanowires.

Areas of Interest

  • Lead halide perovskites and performance enhancing additives
  • Carbon cell infiltration
  • Green solvents
  • Solvent engineering for printed photovoltaics
