Abstract

This article covers the background and related science associated with a thermochromic window. A thermochromic window is a device that changes its reflectance and transmission properties at a specific critical temperature. At this temperature the material undergoes a semiconductor-to-metal transition—at low temperature the window will let in all of the sun's energy while above the critical temperature it will reflect the infrared portion of the sun's energy. Hence a thermochromic window could be used to significantly reduce air conditioning costs, which has consequential positive benefit in reducing electricity consumption and hence green house gas emissions. This article details the underlying science in making a new thin-film thermochromic coating by chemical vapor deposition; it describes the underlying physical chemistry associated with the semiconductor-to-metal transition and shows how substitutional doping within a crystal lattice can be used to lower the thermochromic switching temperature.
