Why do grid-structured Wo 3 films improve electrochromic performance?

The improved electrochromic performance of grid-structured WO 3 films is mainly attributed to thegrooves and channels inside the WO 3 films controls the ions insertion and extraction kinetics leading to an enhanced charge transfer reaction, also, the enhanced charge transfer reaction accelerated the degradation of WO 3.

What are the advantages of grid-structured Wo 3 films?

Compared to the classical plane WO 3 films, the grid-structured WO 3 films showed an obvious enhancement in theoptical modulation rate and CE value of ~ 50% and 20%, respectively, at the wavelength of 550 nm. Furthermore, the response time of the grid-structured WO 3 films is shortened by over 50% than that of the plane ones.

How are WO 3 thin films measured?

Cyclic voltammetry (CV), chronoamperometry (CA) andelectrochemical impedance spectroscopy measurements of WO 3 thin films were performed in a three-electrode cell system assembled with electrochemical workstation, 1.0 M LiClO 4 Propylene carbonate (PC) as electrolyte, Ag/AgCl as reference electrode and Pt foil as counter electrode.

What is the discharge capacity of a film deposited at 375 °C?

The capacities of the film labeled as a, b, c, and d correspond to the film deposited at 175, 600, 575, and 375 °C, respectively. The film with a poor crystallinity obviously possessed the lowest discharge capacity of only about 20 µAh cm −2 µm −1.

What are the volume strain energies of films with orientation 003 & 014?

On the other hand, the volume strain energies of the films with orientation (003), (014), and (110) are 126.2, 78.4, and 76.1 J m −3, respectively, due mainly to lattice misfit. [272, 273]
