Benjamin Allsopp I am currently in my second 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. UV light induced fluorescence in oxides glasses is a primary
focus in my research. I graduated the University of Huddersfield with first class honors 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 do metal ion doping on the optical properties and structure of soda lime silica glasses for photovoltaic applications

A series of Na2
-CaO glasses containing low doping concentrations (0-0.2 mol%) of d0 transition metal oxides was prepared
by a melt quenching technique. Such materials may be suitable material for photovoltaic applications as they have been demonstrated
to fluoresce under excitation from UV light to give intense visible emissions. 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 these glasses. Initial results will be presented here.
