Abstract
The present invention has as its subject an electrochromic pane including two glass sheets (1, 2), each coated with a transparent electrically conducting film (3, 4) and separated by an electrode of electrochromic material (5), an electrolyte (6) and a counter-electrode (7). The electrically conducting films (3, 4) are, on the one hand, connected by current supply leads (8, 9) to an electrical supply system generating a potential difference (U.sub.1) according to a desired modification to the coloration of the electrochromic material and, on the other hand, are connected to each other at least at a portion of their periphery by an electrically conducting material (11).
Claims16
An electrochromic pane comprising:
- first and second glass sheets, each coated with a transparent electrically conducting film;
- a first electrode of electrochromic material formed on the first glass sheet;
- a counter-electrode of electrochromic material formed on the second glass sheet;
- an electrolyte formed between the first electrode and the counter-electrode;
- electrical supply leads for connecting the electrically conducting films to an electrical supply system generating a potential difference (U.sub.1) as a function of a desired modification of a coloration state of at least one of the first electrode and the counter-electrode;
- and
- an electron conducting material connecting the electrically conducting films to each other at least at a portion of their periphery for creating a controlled short-circuit between the electrically conducting films, wherein the electron conducting material is filled between the first and second glass sheets by contacting the conducting films.
