Sir Richard Friend

Sir Richard H. Friend is the Cavendish Professor of Physics and a Fellow of St. John’s College at the University of Cambridge. His pioneering research of semiconducting polymers demonstrated how plastics could be appropriately processed for use as electronic devices. The revolution in technology this sparked has already been applied in commercial products, such as cell phone screens, and researchers around the world are actively working to develop new low-cost, thin, and flexible displays and solar cells.

Friend has over 800 publications in scientific journals, more than 40 patents, and has received numerous honours and awards for his work. He research interests focus on the development and characterisation of polymer light-emitting diodes, thin-film field-effect transistors, time-resolved optical spectroscopy, photovoltaics, and molecular conductors and magnets.
