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.

Teaching

  • EG-D10 Team Project & Individual Dissertation

    The module is where this program ultimately culminates with the final development stages and realisation of a team based project (as defined at the recruitment stage) with individual aspects considered and assessed as a final dissertation submission. The nature of the dissertation will be dependent on the nature of the specialisation of the participant. During the period of this module, a preparatory period will be followed by participants spending (or utilising remote engineering techniques) a period of circa. 3 weeks in-country delivering the project, with support from academic team leads and other supporting staff, stakeholders or collaborators. This will be concluded with a debrief and final dissertation writing period.

  • EGCM01 MSc Research Practice

    A Masters level course to deliver knowledge and skills on how to write and submit scientific papers and reports. The course requires that the students prepare multiple reports focused on specific aspects involved in preparing a draft publication of journal quality. Research data is gathered and, subject to suitable data analysis, is used to write a draft publication. In addition to this, a graphical abstract for a highly cited paper in a relevant chosen field needs to be prepared, as does a letter to an editor. For the paper writing, data is gathered from laboratory-based work and the students must analyse the data and write up the results as a suitable manuscript. They must make a reasoned choice of journal; then follow the format required by that specified journal and its instructions. They must present results appropriately and of the correct quality and then describe and discuss these. The students must also prepare a substantial literature survey (up to 5000 words) on a topic in chemical or biochemical engineering. The course is designed as such so there are multiple smaller assignments prior to the substantial literature review so students can learn and improve through the duration of the course.

  • EGSM17 Concept Development and Application Pt1

    The module is the first of two that involve the development, synthesis and application of scientific, engineering, personal, professional and project management skills to deliver an approach to a solution of the specific group and individual projects. It will require and develop self-organisation skills and the critical evaluation of options and results, as well as developing technical and specialist knowledge around sustainable engineering solutions in the project area. This module is focused on creative techniques including human-centred design and design thinking techniques.

  • EGSM20 Concept Development and Application Pt2

    The module is the second part of two that involve the application of personal, professional, project management and both ¿library¿ and field based research skills to develop an approach to the solution of the specific group and individual projects, The participant will gain experience in working independently and in a group on the team and individually assigned element of the project, utilising basic accepted planning procedures. This second part is ¿in-country¿ (field) based and will be approximately one week in duration. During this period, participants will gather field data through community engagement to ensure key stakeholder and end user requirements are met. Consideration will also be given to impact evaluation and monitoring and a revised project plan will be developed. It will require and develop self-organisation and the critical evaluation of options and results, as well as developing technical knowledge in the chosen topic, all in a ¿real¿ field environment.

  • EGSM23 Circular Economy and Sustainable Engineering

    The module has been designed to promote the role of circular economy and sustainable engineering within industry, commerce and society. It will equip graduates with the knowledge and skills to help industry and commerce to reduce their environmental impacts and support the objectives of sustainable development.

  • EGSM27 Circular Economy and Sustainable Engineering (ELM Pathway)

    The module has been designed to promote the role of circular economy and sustainable engineering within industry, commerce and society. It will equip graduates with the knowledge and skills to help industry and commerce to reduce their environmental impacts and support the objectives of sustainable development.
