Abstract
The present application discloses a method for preparing an electrochromic device. The method includes placing an edge protection material on a first and second substrates, placing a first and second interlayers respectively within the edge protection material on the first and second substrates, wherein the edge protection material surrounds edges of the first and second interlayers, and interposing an electrochromic film between the first and second interlayers. The edge protection material prevents chemicals in the first and second interlayers from entering into the electrochromic film.

An electrochromic device comprising:
- a first portion comprising:
- a first substrate;
- and
- a first interlayer disposed on the first substrate;
- a second portion disposed on the first portion, the second portion comprising:
- a second substrate;
- and
- a second interlayer disposed on the second substrate;
- an electrochromic film disposed between the first interlayer and the second interlayer;
- and
- an edge protection seal disposed between the first substrate and the second substrate and around the first interlayer and the second interlayer, wherein
- the first interlayer is narrower than the first substrate,
- the second interlayer is narrower than the second substrate,
- the edge protection seal covers a portion of inner surface of the first substrate that does not overlap with the first interlayer,
- the edge protection seal further covers side surfaces of the first interlayer and the second interlayer, without covering side surfaces of the first substrate and the second substrate, and
- the edge protection seal is electrically conductive and functioning as electrodes of the electrochromic film.
