My research broadly encompasses Energy Materials & Devices, in two main areas:

Photovoltaics

I lead Swansea's "Materials-Hub" as part of the WEFO funded SPARC II project, and as part of the SPECIFIC-IKC (EPSRC EP/N020863/1) and Sêr Solar programs, my research area focuses on solution processed photovoltaic materials and device physics. My PV research group utilizes time & frequency domain techniques such as Intensity Modulated Photovoltage Spectroscopy (IMVS) or Transient Photovoltage Decay, to characterize carrier transport, recombination and mobility in photovoltaic devices. 

Two new projects were started in October 2018. The first will develop ultra-light weight flexible tandem silicon/perovskite solar cells in collaboration with IQE plc. The second (EPSRC EP/R032750/1) is a collaboration between Materials Engineering and Computer Science to develop the next generation of novel perovskite powered IoT devices. I am also very excited to be involved with the SUNRISE GCRF (EP/P032591/1) project with the aim to rapidly accelerate and prove low cost printed PV for use in off grid Indian communities.

Thermoelectrics

I lead SPECIFIC's newest research activity on novel solution processable thermoelectric materials and devices, focusing on organic and hybrid materials. See our latest work in Advanced Materials and Advanced Energy Materials on SnSe thermoelectric generators.

Teaching

  • EG-218 Materials for Energy

    This module starts with short practical sessions (3 x 3 hours) where the students will be introduced to lab-scale manufacture of energy materials devices - namely dye-sensitised solar cells. This will introduce the students to many of the manufacturing methods that are used for a range of lab scale energy technologies. For the remainder of the module, we will then move to the lecture theatre and group-work environment to introduce the concept of the Energy Trilema, i.e issues related to energy security, energy equity, and environmental sustainability. Materials developed and used for energy generation and storage are critical to all aspects of the Trilema and the large amounts of UKRI funding available reflect the challenges faced by Materials Scientists in their respective fields. The module is student led. After the practical session, students will have an opportunity to choose the energy sector that most interests them. They will then conduct an individual literature search to find a particular filed of materials research that is critically important to their chosen energy sector and more importantly, the Energy Trilema. In groups the students will then decide which field to base their assessment on. In groups the students are required to produce a poster, based on a research paper of their choice. They will then present their poster to a panel. Self and peer assessment will be used throughout and guest lecturers will give their perspectives on energy materials research. The module will be 100% continually assessed throughout the semester

  • EG-286 Materials Practicals 2a: Microstructure Development in Alloy Systems

    This module is concerned with the microscopic examination, measurement and interpretation of the microstructures of metals. This involves the development skills in the microstructural characterisation of metals and the development of sound microstructural measurement methodologies. This is then reinforced by logical reasoning based on an understanding of binary phase diagrams of the nature of the phase transformations occurring in metals and of the influence of processing on microstructure. This module also details the mathematical descriptions necessary for the solution of a variety of critical engineering problems, with an emphasis on materials processing.

  • EGSM12 Applied Instrumental & Analytical Techniques

    The various research groups based in the department of Materials Engineering hosts a truly World-class suite of materials and coatings characterisation and analysis equipment. The module is designed to give an overview of all the techniques available to students during their postgraduate research.
