Abstract:
Optoelectronic devices – electronic devices that produce, detect, or control light – are ubiquitous in our daily lives. They are present in everything from LED display technology and fibre-optic commnications to solar cells and x-ray detectors for medical imaging. But in large part, optoelectronic devices are still built around inorganic materials – things like the crystalline silicon found in most photovoltaic technology, or the erdium-doped glasses found in optical fiber amplifiers. In this talk, I will present some of our research group’s recent efforts to produce optoelectronic devices based on two different types of solution-processable materials: conjugated polymers and lead halide perovskites. In particular, the talk will highlight our recent work in the area of perovskite solar cells and photodetectors.

Dr. Kelly is an Associate Professor of Chemistry at the University of Saskatchewan and a Tier II Canada Research Chair in Photovoltaics. He received his BSc in Chemistry from Memorial University in 2005 and his PhD from the University of British Columbia in 2009. From 2009 – 2011 he held an NSERC post-doctoral fellowship at the University of California, San Diego, after which he began his independent career at the University of Saskatchewan. His interdisciplinary research group is focused on improving the performance and lifetime of optoelectronic devices, with an emphasis on new solar cell technologies. To this end, he and his research group explore novel approaches to the synthesis, processing, and characterization of both organic electronic materials and lead halide perovskites.
