Jenny Nelson (United Kingdom) is a Professor of Physics at Imperial College London, where she has researched novel varieties of material for use in solar cells since 1989. Her current research is focussed on understanding the properties of molecular and hybrid semiconductor materials and their application to solar energy conversion. This work combines fundamental electrical, spectroscopic and structural studies of molecular electronic materials with numerical modelling and device studies, with the aim of optimising the performance of solar cells and other devices based on molecular and hybrid materials. She also works with the Grantham Institute for Climate Change at Imperial to explore the mitigation potential of renewable energy technologies. She is an ISI Highly Cited Researcher in Materials Science and has published over 250 articles in peer reviewed journals, several book chapters and a book on the physics of solar cells. She holds a number of awards including the 2016 Institute of Physics Faraday medal and was elected as a Fellow of the Royal Society in 2014.
