Prof. Jenny Nelson
Jenny Nelson is a Professor of Physics at Imperial College London, where she has researched novel varieties of material for use in solar energy conversion since 1989. She studied Physics at the universities of Cambridge (BA, 1983) and Bristol (PhD, 1988) before starting research into nanostructured materials for novel solar cells at Imperial College London in 1989, as the first Greenpeace Fellow. Her current research is focussed on understanding the properties of molecular and hybrid semiconductor materials and their application to solar cells. This work combines fundamental electrical, spectroscopic and structural studies of molecular electronic materials with numerical modelling and device studies, with the aim of optimising device performance. She also works with the Grantham Institute for Climate Change at Imperial to explore the mitigation potential of renewable energy technologies, and currently leads the Institute’s Mitigation team. She was awarded the Institute of Physics Joule Prize in 2009 and the Royal Society Armoureres’ and Brasiers’ Company Prize in 2012 and was selected as a RISE Leader by the UK Engineering and Physical Sciences Research Council in 2014. She is an ISI Highly Cited Researcher (2014 and 2015) and has published over 250 articles in peer reviewed journals, several book chapters and a book on The Physics of Solar Cells. She was elected as a Fellow of the Royal Society, and as Fellow of the Institute of Physics, in 2014.

Dr. Juan Cabanillas-Gonzalez

Juan Cabanillas-Gonzalez completed his Physics PhD in 2004 at Imperial College London being supervised by Prof. Donal Bradley, one of the worldwide leading scientists in the field of organic optoelectronics. His doctoral work comprised the study of charge transfer and energy transfer interactions in disorder mixtures of semiconducting polymers, (10.1103/PhysRevB.71.014211 and 10.1021/cm0496669 respectively). In 2003 he moved to Politecnico di Milano to work as post-doc with femtosecond time-resolved spectroscopy. There he would made contributions on understanding the process of charge photogeneration in conjugated polymers (10.1103/PhysRevB.71.155207, 10.1002/adma.201102015), picosecond charge transport under electric fields monitored with pump-probe spectroscopy (10.1103/PhysRevLett.96.106601) and monitoring of local electric fields in field effect transistors under operation conditions (10.1002/adfm.200801264, 10.1016/j.orgel.2011.09.023). Since 2010 he works as Ramon y Cajal fellow and Senior Scientist at IMDEA Nanoscience in Madrid. His research nowadays is focused on understanding the relations between polymer chemical structure and emission / optical gain properties for the design of efficient optically pumped lasers, (10.1002/adma.201301703). He is corresponding author of articles in prestigious journals such as Physical Review Letters, Advanced Materials or Advanced Functional Materials. ResearchID code: M-1026-2014.
