Influence of deposition temperature on electrochromic properties of sputtered W03 thin films
Junqiang Wang,John Bell +1 more
TL;DR: In this article, the influence of deposition temperature on the electrochromic properties of reactively sputtered WO3 films has been investigated, and it was shown that the resistance of the films during the electrochemical process increases with increasing substrate temperature.

The kinetic behaviour of ion transport in WO3 based films produced by sputter and sol–gel deposition:: Part I. The simulation model
TL;DR: In this article, a new simulation model for charge injection and extraction in electrochromic WO 3 films under conditions of constant current during the charge injection process was developed, which was applied to the constant current coloration and bleaching of electro chromic films, and values for the diffusion coefficient and other model parameters were obtained by fitting the model to experimental data.

The kinetic behaviour of ion injection in WO3 based films produced by sputter and sol–gel deposition: Part II. Diffusion coefficients
Junqiang Wang,John Bell +1 more
TL;DR: In this paper, the use of AC impedance spectroscopy for kinetic study of the ion intercalation into WO 3 films is reviewed, and methods for extracting the diffusion coefficient of ion diffusion process from AC impedance Spectroscopy data are described.

Degradation mechanisms in electrochromic devices based on sol-gel deposited thin films
Anthony T. Baker,S.G Bosi,John Bell,John Bell,Douglas R. MacFarlane,B.G. Monsma,Igor Lvovich Skryabin,Junqiang Wang +7 more
TL;DR: In this paper, the authors describe the device fabrication techniques and some initial results on the degradation of devices based on sol-gel-deposition electrodes, and show that while the tungsten oxide electrodes can be cycled many hundreds of times in liquid electrolytes, degradation appears in the TiO 2 electrode.

Junqiang Wang,John Bell,Igor Lvovich Skryabin +2 more
- 14 Oct 1997
TL;DR: In this article, the authors used a model based on constant current charge injection into electrochromic WO3 electrodes to calculate voltage-time curves, concentration profiles and surface concentration of lithium for the electro chromic process at WO 3 electrodes.
