Claes-Göran Sture Granqvist (born 25 December 1946, Helsingborg, Sweden)[1] is a materials physicist[2] and Professor of Solid State Physics at Uppsala University in Sweden.[3]
Granqvist is considered a pioneer and expert in photochromic materials[4] and energy-efficient building materials such as glass,[2]
paint,[5] and wood.[6]
In 1975, Granqvist was a Postdoctoral associate at Cornell University, USA. In the period of 1976–89, he held various research positions at Chalmers University of Technology.
From 1989–93 he was a Full Professor of Experimental Physics at Gothenburg University.
Since 1993, he is Full Professor of Solid State Physics[10] and the Head of the Division of Solid State Physics at the Department of Engineering Sciences, The Ångström Laboratory, Uppsala University. In the period 1997–2006 he was the Vice Rector/Senior Advisor for External and International Affairs at Uppsala University.[1]
Granqvist has been involved in the development of several technology companies, including Radicool and Coat AB (formed 1986). In May 2002, he and others at Uppsala University won the Venture Cup competition for best university spin-off business plan. This enabled Granqvist to found ChromoGenics in 2003[11] with Greger Gregard and other researchers. Granqvist continues to be a member of the board of the company.[12]
Granqvist introduced the term "smart window" in the 1980s, brainstorming ideas with scientists from Lawrence Berkeley National Laboratory in California to make building materials more energy efficient. Granqvist used the term to describe a responsive window capable of dynamically changing its tint.[2]
After initially examining thermochromic, photochromic and electrochromic materials, he focused on electrochromic materials.[11]
He has developed electrochromic glass for ‘‘intelligent windows’’ by using coatings of tungsten-doped vanadium dioxide to detect and change with environmental conditions.[14][2]
Granqvist's work as both a researcher and teacher has significantly driven Sweden's development of electrochromic materials.[11]
As of 2021, Granqvist has an h-index of 70 and has been cited at least 28,400 times for 600 papers.[15]
He had published at research papers in mostly refereed journals and over 30 books, and has given invited conference presentations at about 250 international conferences and chaired about 30 international meetings.
