Bethan Charles


Bethan joined the group in January 2020 as a postdoctoral research associate. Shegraduated from Durham University in 2013 with an MPhys in Physics; her final year project investigated the efficiencies of dye-sensitized photovoltaic devices. After her studies she volunteered as a Maths teacher in India before moving to London, working as an analyst in the energy industry.

In 2015 Bethan decided to move back to science, completing a Master of Research degree and then PhD at the University of Bath with Dr Daniel Wolverson, Prof. Chick Wilson and Prof. Mark Weller. As part of her PhD Bethan spent a term at the Ludwig-Maximilian University of Munich working in the group of Prof. Jochen Feldmann. Her work focused on the structure-property relationships of hybrid-halide perovskites for use in photovoltaics..

Current Research

Bethan works on characterising luminescent materials for spectral convertors. She is investigating systems for luminescent downshifting (LDS) layers which convert UV to visible light. This has the potential to increase the efficiency of solar cells by mitigating heating or reducing damage caused by UV radiation. She also works on the optical characterisation of thermoresponsive polymers with aggregation-induced emitter (AIE) properties.
