Dr Chris Groves, BEng PhD FHEA
(email at email@example.com)
Chris Groves is Lecturer in Organic Electronics in the School of Engineering and Computing Sciences at Durham University. He graduated with a 1st class honours degree in Electronic Engineering from Sheffield University in 2001, winning the Mappin Medal for graduating with highest honours. Thereafter he undertook a PhD in advanced optical recievers at the same University, for which Bookham Technologies (formerly Marconi) provided a CASE sponsorship, which was completed in 2004. He changed research field to organic electronics, specifically photovoltaics, by undertaking postdoctoral positions at the Cavendish Laboratory in Cambridge University working on computational modeling, and then at the Department of Chemistry in the University of Washington, Seattle working on scanning probe measurements. He took up his post at Durham University in 2009.
Organic materials offer the opportunity to dramatically reduce the cost of electronic devices because the active materials can be printed, much like a newspaper. One of the most important applications of this technology is in gathering solar energy through photovoltaics. Although organic photovoltaics are improving rapidly, it is still relatively difficult to understand why one set of devices work whilst others do not. Dr Groves uses modelling and experimental techniques to improve this understanding. In particular he concentrates his efforts on understanding the links between the structure of a solar cell and its performance using Monte Carlo charge transport models. Dr Groves is author of more than 30 journal articles and conference proceedings in addition to gaining over £250,000 in research funding as principle investigator, including funding from the EPSRC and Royal Society.
