Where are electrochromic materials used?

Electrochromic materials are used to control the flow of light. These applications are utilized as smart windows or mirrors. Applications are in anti-glare car rear-view mirrors [101], smart sunglasses, and in devices for optical information and storage. Several classes of organic electrochromic materials are known.

What is an electrochromic display?

The term ‘Electrochromism’ refers to the phenomenon whereby a material undergoes a physical color change in response to an electrical stimulus. Electrochromic displays are produced by printing thin layers of these materials with high-performance electrolytes into a flexible ‘electrochromic stack’.

What is an electrochromic roof?

This unique glass is often used in construction thanks to its ability to block light very quickly. The technology is quite simple. According to ExplainThatStuff, electrochromic glass features up to five layers with a separator in the middle.

What is ion storage layer?

Generally, the ion storage layer that is located on the counter electrode is used as a charge storage film and this film is in a reduced (oxidized) state as the electrochromic film is oxidized (reduced). Therefore, the ion storage layer is an important component to achieve improved electrochromic performance.

What is Mercedes Magic Sky Control?

MAGIC SKY CONTROL®, obviously, due to its name, concerns the roof of a Mercedes-Benz vehicle. Taking and evolving the Panorama roof, MAGIC SKY CONTROL® is designed to prevent heat and radiation from entering your car by blocking thermal energy and UV and infrared ray absorption.

What is an electrochromic material?

Electrochromic materials are able to vary their coloration and transparency to solar radiation, in a reversible manner, when they are subjected to a small electric field (1–5 V). The main materials with electrochromic properties are metal oxides of transition, in particular WO 3, MoO 3, IrO 2, NiO, and V 2 O 5.

What are electrochromic windows and how do they work?

Electrochromic materials, also called switchable materials, are usually used in the form of thin film devices. Electrochromic windows, or smart windows, have finally reached maturity and promise to be the next major advance in energy-efficient window technology.

How reliable are organic electrochromics?

Originally, organic electrochromics tended to suffer from problems with secondary reactions during switching, but recently more stable organic systems have been developed. However, their reliability in harsh environments is questionable, and protective encapsulation may be required. Table 1.
