Electrochromic Device Based on Adsorbable Viologens

Electrochromic device with Prussian blue and HPC-based electrolyte

Given the importance of the development of electrochromic devices (ECDs) for technological applications small devices with Prussian blue (PB)/hydroxypropyl cellulose (HPC) electrolyte/CeO2TiO2 configuration were assembled and characterized. The films of PB were obtained galvanostaticaly by applying 0.45 mA for 300 s. The cyclic voltammetry, in 1 mol L 1 KCl solution, of these films showed a red...

High performing smart electrochromic device based on honeycomb nanostructured h-WO3 thin films: hydrothermal assisted synthesis.

Herein, we report honeycomb nanostructured single crystalline hexagonal WO(3) (h-WO(3)) thin films in order to improve electrochromic performance. In the present investigation, honeycomb nanostructured WO(3) with different unit size and nanowire array with highly nanocrystalline frameworks have been synthesized via a hydrothermal technique. The influence of hydrothermal reaction time on the hon...

Ultrafast switching of an electrochromic device based on layered double hydroxide/Prussian blue multilayered films.

Electrochromic materials are the most important and essential components in an electrochromic device. Herein, we fabricated high-performance electrochromic films based on exfoliated layered double hydroxide (LDH) nanosheets and Prussian blue (PB) nanoparticles via the layer-by-layer assembly technique. X-ray diffraction and UV-vis absorption spectroscopy indicate a periodic layered structure wi...

Development of Flexible Electrochromic Device with Thin Film Configuration

Low-voltage electrochromic device for photovoltaic-powered smart windows

We report the properties of an all-solid-state electrochromic ~EC! device that can be switched over a useful range of optical transmissions with voltages below 1 V. This switching voltage is smaller than required by other solid-state EC devices reported to date. We attribute the lower-than-normal switching voltage to the use of a thermally evaporated MgF2 thin film as the lithium ion conducting...
