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


As part of the SPECIFIC-IKC, Sêr Solar, and SPARC II research projects, my research area focuses on solution processed photovoltaic materials and device physics. My PV research group utilizes frequency domain techniques such as Impedance Spectroscopy or Intensity Modulated Photovoltage Spectroscopy (IMVS); or time resolved measurements such as Transient Photovoltage/Photocurrent Decay and photo-CELIV, to characterize carrier transport, recombination and mobility in photovoltaic devices, with a particular interest in quantifying loss mechanisms when increasing device size from lab scale to pilot scale, and in the characterization of degradation mechanisms.

Two new projects will be starting in mid-2018. One will develop ultra-light weight flexible tandem silicon/perovskite solar cells in collaboration with IQE plc - PhD scholarship available now. The second is a collaboration between Materials Engineering and Computer Science to develop the next generation of novel perovskite powered IoT devices - postdoctoral positions to be advertised soon.


I lead SPECIFIC's newest research activity on novel solution processable thermoelectric materials and devices, focusing on organic and hybrid materials.

  • EG-218 Materials for Energy

    The module will 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. At the start of the module, 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 write a UKRI (EPSRC) style funding proposal with each member of the group taking charge of a different section. The students will then form panels to assess each others proposals. The module will be 100% continually assessed throughout the semester

  • EGA114 Chemical Engineering Science

    This module will introduce fundamental principles of thermodynamics, physical chemistry and mass transfer relevant to the course including: gas behaviour; properties of pure substances and mixtures; laws of thermodynamics and their applications to energy and state calculations; phase equilibria; diffusive and convective mass transfer; and mass transfer coefficients

  • 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.
