How Do Smart Glass Windows Work

Photochromic glass contains small molecules of silver halide, suspended in the glass itself. When these are exposed to sunlight, a reaction takes place, and electrons in the glass combine with the molecules to create elemental silver; as silver isn’t transparent (it’s, well, silver), this causes the glass to darken.

Does smart glass require electricity?

Smart Glass operates on 110 Volts AC power. It consists of five layers and it use small electrical charge that is approximately 3 to 5 watts per square meter. Smart Glass (electrochromic) uses voltage (12-36 W) and causes lithium-ions to transfer layers and making the glass tint.
