Student Hosted Colloquia: Professor Ted Sargent, University of Toronto, Sapp Center Lecture Hall, 4:30pm (Host: Ian Smith)

About the Seminar: Tremendous progress in the cost-effective conversion of solar and wind energy into electrical power brings about a new challenge: the massive (seasonal-scale) storage of energy. We focus on using computational materials science, spectroscopies including ultrafast and synchrotron, and advances in materials chemistry, to create new catalysts for CO2 reduction and oxygen evolution. I will discuss recent advances including a new high-activity OER catalyst [1] and a low-overpotential CO2 reduction catalyst based on field-induced reagent concentration [2]. I will also touch on related materials design problems in optoelectronics, including the design of composite organic-inorganic materials for photon-to-electron [3] and electron-to-photon [4] conversion.[1] B.

Rogers Sr. Department of Electrical and Computer Engineering at the University of Toronto. He holds the Canada Research Chair in Nanotechnology and also serves as Vice President - International for the University of Toronto. He is founder and CTO of InVisage Technologies Inc. of Menlo Park, and a co-founder of Xagenic Inc. of Toronto. He is a Fellow of the Royal Society of Canada; a Fellow of the AAAS "...for distinguished contributions to the development of solar cells and light sensors based on solution-processed semiconductors;" and a Fellow of the IEEE "... for contributions to colloidal quantum dot optoelectronic devices." He is Fellow of the Canadian Academy of Engineering for “…ground-breaking research in nanotechnology, applying novel quantum-tuned materials to the realization of full-spectrum solar cells and ultra sensitive light detectors. The impact of his work has been felt in industry through his formation of two start-up companies."He received the B.Sc.Eng. (Engineering Physics) from Queen's University in 1995 and the Ph.D. in Electrical and Computer Engineering (Photonics) from the University of Toronto in 1998. ** This seminar is sponsored by Dow
