Jenny Nelson, Imperial College London
Professor Jenny Nelson has made several theoretical contributions to the field of photovoltaics (PV) materials and devices research. Her work has concerned the efficiency of solar to electric power conversion and routes reduce the cost reductions of solar cell manufacture. Her work is known both in the UK and overseas. In her early work she was responsible for developing the theoretical and computational tools for the characterisation and design of the quantum well (QW) solar cell.

As an EPSRC Advanced Fellow she focused on the development of radically lower cost PV materials, addressing an outstanding problem in the emerging dye-sensitised solar cell (DSSC) technology. She helped to show that electronic disorder in the nanocrystalline TiO2 electrode is a major factor controlling charge transport and recombination dynamics, and how these processes influence device performance.

Since 2000 she has focused on the application of solution processable, organic semiconductors as PV materials. Here she has worked to relate the electrical properties of molecular semiconductors to their chemical and physical structure, a critical contribution because mobility limits the efficiency of organic PV devices, and has also addressed the relationship between the structural, electronic and spectroscopic properties of materials and the resulting device performance. Her work has attracted collaborations with industrial and academic partners.

Trystan Watson, Swansea University
Trystan started his academic career with a Chemistry degree at Swansea University spending a year out as an analytical chemist at 3M. He then transferred to the College of Engineering to carry out a Doctorate in Steel Technology. As part of this doctorate he used scanning electrochemical techniques to characterise corrosion phenomena such as Filiform corrosion on packaging substrates. He also co-invented a novel packaging coating to inhibit corrosion during high temperature heat treatments.

Trystan then moved to Corus Strip Products as a product development engineer as well as a theme leader for the process technology group in the engineering doctorate scheme. It was there that he became a chartered engineer with the Institute of Materials Minerals and Mining.

In 2007 Trystan returned to academia to take up a post doctoral research position on the development of dye-sensitized solar cells on metal substrates. In this time he has published work in a range of areas from fast sintering, induced scattering, in-situ monitoring of dye uptake and corrosion testing of novel substrates as well as UV photodegradation of the devices in long term testing. He is the co-inventor of a sintering method capable of reducing the titania sintering step from 30 minutes to 12 seconds. His current research activities are in the scaling of thin film photovoltaics including CZTS and organolead halide perovskites.

Trystan is married with two daughters and a son and spends most of his home life wrapped around their fingers.

Trystan is a senior lecturer in Photovoltaics at SPECIFIC.
