Outreach

A recording of the webinar for the public on The history, present and future of renewable energy 5 June 1430-1600 CEST, 1330-1500 BST can be seen here. This webinar is given by the Horizon 2020 Innovative Training Network, ITN MAking pErovskiteS TRuly explOitable which I coordinate.
Solar Commission Report
I chair the Solar Commission whose aim is to show how the UK’s extensive innovation and industrial capabilities can be harnessed to enable the UK to play a leadership role in what will undoubtedly be one of the key energy generation technologies of the coming decades. This report was launched at the House of Lords Tues 9 July 2019.
TEDX talk
This 16 minute talk was given at the University of Bath in 2014 where I describe my research on new organic light emitting diodes, photovoltaic devices and novel solar photovoltaic cells.

Solar cells

Solar cells are devices that produce electricity from the sun's energy through the creation and subsequent dissociation of an exciton. The way in which they work is similar to natural photosynthesis.

What types are there?

There are several solar cell technologies and in each, the light-active component and other cell materials are different.

Protein/Enzyme simulation

The relationship between the structure of a protein and its function is vital to understanding how molecules give rise to biological effects. The flexibility and dynamics of proteins in many cases drives their functional activity. A modelling tool was created by Dr Stephen Wells, Bath Chemical Engineering that we further developed, see Tom McManus' PhD Thesis, University of Bath 2019 . It is based on the Framework Rigidity Algorithm, FRODA, and has been combined with complementary modelling methods developed by Dr Marc Van der Kamp, Bristol Biochemistry .

We studied the enzyme citrate synthase shown below responsible for catalysing the first reaction of the citric acid cycle. The temperature variation of its rigidity influences extremophiles, organisms who thrive in different temperature regimes. See T J McManus et al Phys Bio 17


The software is being used by Dr Chris Pudney, Bath Biology & Biochemistry who develops experimental approaches to rapidly test proteins for their native function based on accurate detection of their dynamics and flexibility, termed the dynamic profile. There are industrial applications and potential for use in a clinical setting.

Organic Materials and Devices

We're all taught at school that plastic is an insulator, but some carbon-based small molecules and polymers do conduct electricity. Unlike silicon-based electronics, organic electronics are relatively low performance but cheap and flexible. And when they conduct, they can light up, click here for my article on lighting based on organic light emitting diodes (OLEDs), be used in displays, or convert light to current in photovoltaics.

to access the press release on the Horizon2020 research project Extmos, EXTended Model of Organic Semiconductors, that I coordinate. The motivation for my research on flexible and printable electronics is discussed with Enrico Da Como. A 3 minute video has been filmed on the Extmos research that can be seen on that website and can also be found by clicking here.

What devices are there?


  • Organic Field Effect Transistors used in smart packaging, brand protection, security, smartcards, distribution tagging and Radio Frequency Identification Devices, interactive media, disposable electronics, and (flexible) display backplanes.
  • Display Devices Incorporation of flexible electronics in textiles can be used in phototherapy,

    clothing for the public services.
  • Organic devices are being developed that can restore or replace functions of the human body through managing the interface between electronic devices and cells, tissues and organs.

    At the University of Bath, I work with the Molecular Optolectronics group headed by Dr Enrico Da Como.
