Summary: Hybrid electrochromic devices combine the advantages of solid-state and liquid-based devices to optimize their performances. In this study, a new redox shuttle, thiolate/disulphide, was combined with a transparent thermally curable vinyl-acetate polymer to create a solid-state electrochromic (EC) device. Compared to a device based on I-/I3-, the EC device based on T-/T2 showed higher transparency and coloration efficiency in the visible region of the solar spectrum. Additionally, it displayed a slower self-bleaching process and only lost 30% of its coloration after 1 hour at open circuit, making it highly suitable for smart windows applications that require energy-saving.

Summary: This study aims to prepare and characterize a novel polymer-free gel electrolyte (PFGE) based on fumed silica, and apply it to TiO2 electrochromic devices (ECD). A series of liquid electrolytes with different molar ratios of lithium chloride (LiCl) and ethylene glycol (EG) were prepared, and their ionic conductivities were measured to determine the highest ionic conductivity composition. The optimized composition was used to prepare PFGE by adding fumed silica as the polymer-free gelling agent. ECDs were then prepared by sandwiching PFGE between TiO2 electrochromic electrode and fluorine-doped tin oxide (FTO) counter-electrode, and notable electrochromic properties were observed.

Summary: Transparent conductors are crucial for optoelectronic and flexible electronic devices, with oxide/metal/oxide (OMO) multilayer films showing promise as an alternative to traditional transparent conductive oxides (TCOs). However, deposition methods like magnetron sputtering or thermal evaporation can lead to device performance deterioration due to ion bombardment or high temperatures. New techniques, such as reactive plasma deposition (RPD) for high-quality MGZO films and ultrathin Ag films prepared by magnetron sputtering, are being explored to improve conductivity and transmittance in OMO structures.

Summary: Over the past few decades, the research on electrochromism has focused on altering the optical transmittance of electrochromic (EC) materials using a small applied voltage. Tungsten oxide (WO3) is commonly used in EC devices (ECDs) to achieve this effect. In this study, WO3 films were produced using a sol-gel spin-coating method, and the influence of various transparent conducting oxides (TCOs) on the construction of ECDs was investigated. The combination of fluorine-doped tin oxide (FTO) and indium-doped tin oxide (ITO) as the TCO and counter electrode, respectively, exhibited the highest coloration efficiency.
