Dr Yongtao Qu

Senior Lecturer

Department: Mathematics, Physics and Electrical Engineering


I received my BSc degree in Materials Chemistry and MSc degree in Inorganic Chemistry in 2008 and 2011 respectively. I then joined Northumbria University in 2012 and awarded a PhD degree in Physics in 2016 for my work in thin film solar cells from nanoparticle inks. My current research interest is to explore and understand the interfaces between the materials within the solar cells over a full range of length scales (atom to device), from the investigation of atomic ordering in the absorber to the improvement of PV devices via reduced back contact barrier using alternative nanoparticle fabrication strategy. I am directly contributing as the Centre manager to the running of the EPSRC Centre for Doctoral Training in Renewable Energy Northeast Universities (ReNU), partnering with Durham and Newcastle Universities and 36 industrial partners, as well as being a partner on the North East Centre for Energy Materials.
