Imagine if the picture window in your living room could double as a giant thermostat or big screen TV. A discovery by researchers at the University of British Columbia has brought us one step closer to this becoming a reality.
Researchers at UBC Okanagan found that coating small pieces of glass with extremely thin layers of metal like silver makes it possible to enhance the amount of light coming through the glass. This, coupled with the fact that metals naturally conduct electricity, may make it possible to add advanced technologies to windowpanes and other glass objects.
鈥淓ngineers are constantly trying to expand the scope of materials that they can use for display technologies, and having thin, inexpensive, see-through components that conduct electricity will be huge,鈥 said UBCO associate professor and lead investigator Kenneth Chau.
鈥淚 think one of the most important implications of this research is the potential to integrate electronic capabilities into windows and make them smart.鈥
The next phase of this research, added Chau, will be to incorporate their invention onto windows with an aim to selectively filter light and heat waves depending on the season or time of day.
The theory underlying the research was developed by Chau and collaborator Lo茂c Markley, an assistant professor of engineering at UBC. Chau and Markley questioned what would happen if they reversed the practice of applying glass over metal鈥攁 typical method used in the creation of low-e window coatings.
鈥淚t鈥檚 been known for quite a while that you could put glass on metal to make metal more transparent, but people have never put metal on top of glass to make glass more transparent,鈥 said Markley. 鈥淚t鈥檚 counter-intuitive to think that metal could be used to enhance light transmission, but we saw that this was actually possible, and our experiments are the first to prove it.鈥
Chau and Markley鈥檚 research was published this week in the Nature Publishing Group鈥檚 open access journal Scientific Reports.
