Abstract

As the technology was readily available here at BYU, we decided to make our own electrochromic material to meet our specifications. After a literature review we found a study done by Wang et al. [1] which suggests a preparation method using a thin film of vanadium dioxide to coat glass. Vanadium dioxide is a fascinating material for its property of undergoing a phase transition from a semiconductor to a metal at a temperature of around 68°C [2]. This change in state is accompanied with a change in its optical properties. It can reversibly change from a state of reflectance to a state of transmittance. For this material, the change of state is controlled by temperature (thermochromic) rather than by voltage (electrochromic).
