Biography Summary

Dr. Yuning Li is a Chemical Engineering Associate Professor and a researcher in the Waterloo Institute of Nanotechnology at the University of Waterloo. He is the Editorial Board Member for Advances in Nanoparticles and AIMS Environmental Science, the Associate Editor of Martials Focus, as well as the Editorial Board Member for Organic Photonics and Photovoltaics.

His research group studies optoelectronic materials that are suitable for the mass production of electronics using printing technologies. There is an emphasis on the development of printable electronic materials used in thin film transistors (for flexible displays, smart labels, chemo-/bio-sensors, themoelectrics, and memory devices) and photovoltaics (for solar cells and photodetectors).

The group developed several new p-type, n-type, and ambipolar polymer semiconductors with high mobility up to ~7 cm2/V.s in thin film transistors, which are useful for a range of applications..

Professor Li has invented and co-invented many metal nanoparticle-based conductive inks; one of which has been commercialized by Xerox (the “Silver Bullet” ink). Nanoparticle-based conductive inks are useful for printed organic electronics, since nanoparticles of < ~100 nm can be merged into conductive films at a low temperature of
