چکیده

A new multilayer electrochromic device has been constructed according to the following pattern: glass1/ITO/WO3/gel electrolyte/BP/ITO/glass2, where ITO is a transparent conducting film made of indium and tin oxide and with the surface resistance equal 8–10Ω/cm. The electrochromic devices obtained in the research are characterized by great (considerable) transmittance variation between coloration and bleaching state (25–40% at applied voltage of 1.5 to 3V), and also high coloration efficiency (above 100 cm/C). Selfconsistent energy bands, dielectric permittivity and optical parameters are calculated using a full-potential linear muffin-tin orbital method. The numerical solution of the Debye-Smoluchowski equations is developed for simulating recombination probability of Li ions in amorphous electrolyte.

تأثیر ماندگاری محلول بر خواص نوری و الکتروکرومیکی لایه‌های‌ نازک 3WO برای ساخت پنجره‌های هوشمند

This paper proposes a suitable method for increasing effective surface area of electrodeposited WO3 thin films. This is done because effective surface area improves optical and electrochromic properties in smart windows. Therefore, we investigated precursor aging atperoxytungstate precursor (0, 24, 48 and 72 h). Experiments showed by increasing aging time of the precursor solution, larger aggre...

Improving Electrochromic Properties of WO3 Thin Film with Gold Nanoparticle Additive

In this research, WO3 and Au-WO3 thin films were prepared at different temperatures using the sol gel method. The effect of gold nanoparticles (GNPs) on the electrochromic properties of WO3 was also studied. 2.5 nm GNP was synthesized through sodium citrate reduction of gold chloride in an aqueous solution. These films were characterized by XRD, SEM, TEM, and spectrophotometer analyses. The fil...

Correlation between crystal structure and optical properties of copper- doped ZnO thin films

ZnO and Cu doped[1] (CZO) thin films were prepared by radio frequency sputtering. The structural and optical properties of thin films were investigated using X-ray diffraction (XRD), atomic force microscopy (AFM), optical spectrophotometer, and photoluminescence (PL) techniques. ZnO thin films showed crystalline and micro-stress defects in the crystal lattice. Annealing of CZO thin films increa...

Tungsten trioxide (WO3) thin films were coated onto fluorine tin oxide coated glass substrates, using electrodeposition technique via aqueous solution of peroxotungstic acid. WO3 films were evaluated as a function of annealing temperature (60°C, 100°C, 250°C and 400°C). The films were analyzed by field emission Scanning Electron Microscopy (SEM), UV-visible spectrometer and cyclic voltammogram....
