Abstract

Electrochromism in copper oxide thin films deposited using spray pyrolysis technique was successfully demonstrated at 5 V and 10 mA. Cathodic and anodic reactions result to reversible transition between copper oxide and copper. XRD patterns confirm the presence of both CuO and Cu2O on the fabricated films and even after electrochemical cycling supporting the reversible switching behavior. The electrochromic efficiency of the system measures 1.2 cm2/C at 1000 nm. High transmittance modulation was observed in the NIR region which ranges from 19% to 71% at 1000 nm. The reflectance modulation covers up to approximately 50% difference between the two optical states (CuxO and Cu) at 1000 nm.
