Dr Matthew Davies is an Associate Professor and head of the Applied Photochemistry Group in the SPECIFIC IKC, Materials Research Centre, College of Engineering at Swansea University. Matthew is an EPSRC Innovation Fellow, Fellow of the Royal Society of Chemistry (RSC) and Council Member of the Environment, Sustainability and Energy Division of the RSC. His research is focused upon the photochemistry of materials that are useful for low-cost photovoltaic applications, with the ultimate aim of improving stability, light harvesting efficiency and performance. This mainly focusses on perovskite solar cells but also includes research into dye-sensitised solar cells and organic photovoltaics. Particularly interested in the characterisation of re-manufactured devices (“photochemistry/photophysics of the re-use of materials”) and developing materials and processes to enable re-use and re-manufacture within a circular economy to develop for the next generation of solar PV materials. Also has research on developing renewable energy solutions for rural Africa in collaboration with the University of KwaZulu-Natal, Durban, South Africa.
