I am currently in my first year of my PhD, supervised by Dr Paul Bingham, at Sheffield Hallam University. The project consists of development of new glass compositions with enhanced optical, chemical and mechanical properties for the PV module industry. Ionic doping with controlled heat treatments to form optical conversion centres will be the major focus of my research. I graduated the University of Huddersfield with first class honours in an MChem degree in 2014. I have undertaken research in photochromic 2H-pyrans with Vivimed Labs Europe, and synthesis of lead phosphate crystals with Yorkshire Water.
The effects of Bi2O3 doping on the optical properties and structure of

Low doping concentrations of Bi2
-CaO glasses were prepared
by a melt quenching technique. Such a material may be suitable material for photovoltaic
applications. Bismuth in glass has been demonstrated to fluoresce under excitation from
UV light to give visible emission. Initial analyses using UV-Vis-NIR optical absorption
spectroscopy and fluorescence spectroscopy, in conjunction with FT-IR and Raman
spectroscopy, XRF and XRD, have been used to investigate the optical and structural
properties of the glasses as a function of bismuth content. Initial results will be presented here.
