Biography:

Dan Credgington received his PhD from UCL in 2010, where he worked on nano-scale patterning and characterisation of conjugated organic molecules. He subsequently joined Imperial College London as a post-doc working on methods to measure the impact of recombination on the performance of organic solar cells, and the link between morphology and device function. In 2012, he joined the Cavendish Optoelectronics group, in collaboration with the commercial OLED developer CDT. In 2014 he took up a Royal Society University Research Fellowship focussing on understanding the behaviour of excitons within modern organic LEDs, and how they can be controlled. Within the wider Optoelectronics group his interests encompass organic and hybrid heterojunction solar cells and new electrode materials for organic devices. He is the Energy Materials theme coordinator for the Cambridge NanoDTC, a Cambridge Nanoforum fellow and an Official Fellow and College Lecturer at Emmanuel College.

Research Interests

Our group works on flexible light emitting diodes and lasers made from solution-processable semiconductors. These have huge potential to succeed current lighting and display technologies and can be assembled as easily as printing ink on a newspaper. Our research is highly applied, and covers the physics of organic and hybrid light emitting materials, control of exciton spin in working devices and in-situ measurements of charge and exciton recombination in thin films. We are also collaborating with groups in Materials Science on the development of new scalable electrode materials for flexible electronics.

 Dan is currently taking on students with an interest in solution-processed LEDs, lasers and remote phosphors. Those with previous experience of magnetic and/or spectroscopic characterisation of optoelectronic devices, or in developing techniques for in-situ device analysis are particularly encouraged.
