Claes-Goran Granqvist is Senior Professor of Solid State Physics at the Ångstrom Laboratory, Uppsala University, Sweden, and has held his position since 1993. During 1989–1993, he was Professor of Experimental Physics at Gothenburg University, Sweden. Much of Granqvist’s research is concerned with materials—especially functional thin films—for energy efficiency and solar energy utilization in the built environment. Electrochromics-based and thermochromics-based “smart windows” are two examples. Granqvist has published more than 550 scientific articles and about 30 books and conference proceedings. He has given more than 250 invited talks, mainly on energy related issues, and he has organized about 40 international conferences. Granqvist is a member of the Royal Swedish Academy of Sciences and the Royal Swedish Academy of Engineering Sciences. He has received several prizes and awards, most recently the 2015 Jan Czochralski Award. Granqvist is one of the founders of ChromoGenics AB, a company with some 20 employees, for producing electrochromic foils devised for glass lamination.

Electrochromic and Thermochromic Thin Films and Devices: Towards a New Paradigm for Glazings

About forty per cent of the World’s primary energy is used for heating, cooling, lighting and ventilating buildings. New nanotechnologies are able to decrease the use of energy significantly at the same time as the comfort and amenities of the building are improved. This talk surveys a number of options, mostly based on work in the speaker’s laboratory. Foci lie on windows and glass facades with electrochromic and thermochromic properties. Functional principles, thin film preparation and properties, new plasmonic nanomaterials, and technological prospects are discussed.
