Etude electrochrome des couches minces de trioxyde de molybdene.

摘要

Electrochromic materials are those in which it is possible to modulate the transmission or reflection properties under the action of a current or an electric field. This renders these materials very interesting, notably for industrial applications in the manufacturing of intelligent windows.;Molybdenum oxide (MoO3) is a transition metal oxide that offers good optical and electrochromic properties, making it a very good candidate for the manufacturing of electrochromic devices. In this work, we have studied the electrochromic (EC) and photochromic (PC) properties of thin films of molybdenum oxide with three different type of structures, deposited by the thermal evaporation method. The electrochromic study has been performed by a dry lithiation method, therefore by insertion of lithium ions (Li +). The photochromic study has been performed with an ultraviolet lamp. An electrochromic device was manufactured, consisting of an electrochromic layer (EC) of molybdenum oxide in conjunction with a counter electrode (CE) of vanadium pentoxide (V2O5), both these layers being deposited on indium tin oxide (ITO) coated glass.
