Abstract:

For the synthesis of tungsten-oxide-based electrochromic layers, the effect of the addition of polyethylene glycol (PEG) in different concentrations into peroxopolytungstic acid sol followed by thermal treatment at different temperatures on the performance of electrochromic devices (ECDs) is studied. The modification of the tungsten-oxide-layer sol-gel synthesis under optimal conditions (PEG: WO₃ ratio 1∶2, temperature 450°C) provides a significant improvement of the ECD optical contrast and coloration efficiency due to the formation of a highly developed surface of the tungsten oxide layer, enhancing its contact with electrolyte while retaining continuity of the electrochromic layer.

Keywords:
